Photosynthesis Lab Report
Photosynthesis is a process that allows organisms to trap sunlight energy and convert it directly into potential chemical energy. Enzymes are required in order for the biochemical reactions to occur because they act as a catalyst to convert energy from sunlight into chemical potential energy. Two consecutive steps allow the photosynthesis process to take place. These steps are light-independent reactions, and light dependent reactions. The occurrences of Light-independent reactions happen in the STROMA of the chloroplasts. The substances consumed during this reaction are ATP and NADPH. The occurrences of light-dependent reactions happen within the THYLAKOIDS of the chloroplasts. The substances consumed during this reaction is light, which is absorbed by chlorophyll molecules, which then produces hydrogen ions, electrons, oxygen gas, ATP and NADPH. “The light-dependent reactions drive the light-independent reactions, which means the products of the light-dependent reactions, ATP and NADPH, are required for the light-independent reactions to proceed.” (Photosynthesis Lab background) …show more content…
However, organisms such as plants, certain bacteria (cyanobacteria), and algae can carry out photosynthesis as well. The three domains that are able to carry out some type of photosynthesis would therefore be, Eukarya, Bacteria and Archaea. These organisms are known as photoautotrophs, which are autotrophs that use carbon and sunlight to synthesize chemical energy in the form of carbohydrates. (5 | Photosynthesis) The objective of the photosynthesis lab is to evaluate the process and the significance of photosynthesis, define the light compensation point, observe the effect of light intensity and wavelength on the photosynthetic rate of a Spinach leaf, and identify the pigments found in the chloroplasts of spinach leaves by using a Thin Layer Chromatography

    What is the Best Possible Set of Conditions for the Maximum Production of ATP?

    The process of photosynthesis occurs when six carbon dioxide molecules (CO2), six water molecules (H2O), and light energy are added together and result in glucose (C6H12O6) and six oxygen (O2) molecules. There are two stages to this process; light reactions and dark reactions. Light reactions start with chloroplast which absorbs the light. Inside the chloroplast are thylakoids that contain pigments which absorb certain wavelengths of light. Each cluster of pigments is called a photosystem. Photosystem I and II obtain some of the light’s energy. Light first enters chlorophyll A in photosystem II and the electrons inside become excited enough to leave it. Some of the electrons, which just left, enter a chain of reactions called the electron transport chain and it produces ATP. The electrons that couldn’t fit into the ETC move onto photosystem I. Those electrons then get excited by light energy and enter the ETC where they add a hydrogen atom to NADP to form NADPH.…

    Spinach Lab Report

    More specifically, however, this experiment focused on the photo part of photosynthesis, or the light dependent reactions in chloroplasts. Light dependent reactions require the presence of light to function, so that this light can be taken to create ATP and to reduce NADP+ to NADPH. Consequently, light dependent reactions shut down in the absence of light, thereby stopping the production of ATP and NADPH (Sadava et al. 2012). With this information, an experimental hypothesis can be formed that the presence of light will cause the redox activity of the spinach chloroplasts to increase, while the absence of light will cause this activity to decrease. One possible null hypothesis could be that there will be no significant difference in redox activity between spinach chloroplasts that are under light and in the dark. Therefore, the alternative hypothesis must be that there will be a difference in this activity between the two groups of chloroplasts. To test these hypotheses, chloroplasts were extracted from spinach leaves in order to create enriched chloroplasts, which were a vital…

    Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage, where energy from sunlight is captures in Photosystem 2 and then 1, the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP, by the ATP Synthase. The equation for this reaction is 6CO2 + 6H2O  C6H12O6+6O2 or, carbon dioxide +water sugars + oxygen . This reaction takes place on the thylakoid membrane of the chloroplast and uses energy from sunlight to produce compounds like ATP and NADPH. The second stage of photosynthesis is the Calvin Cycle, which takes place in the stoma of the chloroplast. This stage is light-independent or it does not need energy from sunlight. During this reaction ATP and NADPH from Stage 1are used to produce high energy sugars. The reaction is 3CO2 + 6NADPH + 5H2O + 9ATP  G3P + 2H+ + 6NADP+ + 9ADP + 8Pi . Additionally, the three limiting factors of photosynthesis are the light intensity, carbon dioxide concentration, and the temperature. Lastly, the items used in this particular experiment were baking soda to provide CO2, a light to excite the electrons in stage 1, distilled…

    Photosynthesis is the process by which green plants, algae and some bacteria absorb light energy and use it to synthesize organic compounds. In green plants, photosynthesis occurs in chloroplasts, that contain the photosynthetic pigments. Photosynthesis occurs by slightly different processes in C3 and C4 plants. Factors which can affect this are the stomata. Plants can regulate the movements of water vapor, O2 and CO2 through the leaf surface. This is accomplished by opening and closing the stomata, usually found on the bottom…

    Abstract: The purpose of this lab is to separate and identify pigments and other molecules within plant cells by a process called chromatography. We will also be measuring the rate of photosynthesis in isolated chloroplasts. Beta carotene, the most abundant carotene in plants, is carried along near the solvent front because it is very soluble in the solvent being used and because it forms no hydrogen bonds with cellulose. Xanthophyll is found further from the solvent font because it is less soluble in the solvent and has been slowed down by hydrogen bonding to the cellulose. Chlorophylls contain oxygen and nitrogen and are bound more tightly to the paper than the other pigments. Chlorophyll a is the primary photosynthetic pigment in plants. A molecule of chlorophyll a is located at the reaction center of the photo systems. The pigments collect light energy and send it to the reaction center. Carotenoids also protect the photosynthetic systems from damaging effects of ultraviolet light.…

    The lung is a spongy organ made up of of irregularly shaped air spaces called Alveoli. The alveoli are lined by a single layer of flat cells and supported by a mesh of fine elastic fibers. The alveoli are surrounded by a rich network of pulmonary capillaries (Couch and Berger, 2004). Our lungs are a network of connected tubes that bring oxygen from the air into our blood, nourishing the trillions of cells that make up our bodies. The lungs also clean the blood of carbon dioxide waste created when cells use oxygen (Natural Geographic, 2012).…

    Cellular Respiration vs. Photosynthesis

    In cellular respiration and photosynthesis, the reactants flow through pathways to become products in very different ways. Respiration is catabolic, breaking glucose down, while photosynthesis is an anabolic reaction, building glucose. When respiration breaks glucose down, energy is released in small increments. The released energy is used to synthesize ATP, NADH, and FADH2. The NADH and FADH2 go through oxidative phosphorylation to produce ATP and H2O. Photosynthesis uses light reactions to provide energy to build glucose. Inside the thylakoids, where the light reactions take place, there are two types of photosystems, II and I. Photosystem II utilizes light…

    Photosynthesis and cellular respiration are often mistaken as the same thing. Although they are similar in many ways, photosynthesis and cellular respiration are the exact opposite of each other. Not figuratively, but literally the reverse (Photosynthesis). They incorporate the others products while adding some outside energy to create a never ending cycle. This brings us to the photochemical and biochemical reactions of photosynthesis and cellular respiration. In an ordinary photochemical reaction, carbon dioxide, water and light energy produce glucose and oxygen. These products transfer to the biochemical reaction, where light…

    Energy transfers which take place in living organisms

    Plants are able to produce ATP during the light dependent reaction of photosynthesis in the thylakoid of the chloroplast. Red and blue wavelengths of light are absorbed by chlorophyll in chloroplasts on Photosystem II. The chloroplasts are protected and contained by a membrane, but they are close to the surface of the cell to catch the maximum amount of light. Their broad length also allows larger wavelengths of light to be absorbed. The energy absorbed is transferred to electrons and excites them to a higher energy level. This leads to the photolysis of water which results in the formation of hydrogen ions, electrons and oxygen gas. The electrons formed during photolysis then replace those excited by the light. The excited electrons are then passed along the electron transport chain in a series of redox reactions from one carrier to the next. The energy released by this passage is used to activate ATPase to combine ADP and Pi to form ATP. This process of converting ADP to ATP using light…

    Energy Transfers

    Photosynthesis is an anabolic process where plants produce sugars from carbon dioxide, light energy and water. The sugars are used for other anabolic reactions e.g. protein synthesis and the energy required for these reactions comes from ATP which is synthesised from chemical energy into ATP during respiration. The ATP used in plants is made from the conversion of light energy from the sun, to chemical energy by plants, into the form of organic molecules during respiration in all cells. The ATP produced can then be used by cells to perform useful work e.g.…

    Photosynthesis: Cellular Respiration

    Photosynthesis is one way plants(plants are the main source of energy for all things)get energy to do things. The reactants of this are water, carbon dioxide, and although light energy is not a reactant, it is necessary once the energy from the seed is gone. Carbon Dioxide needs to be present for photosynthesis to happen. In lab 7.2, we put an elodea in one test tube, and nothing in the other. We blew into the BTB until it turned a yellow/green color, which meant it had carbon dioxide in it. We filled both…
