Carbon atom Project
Denisse Gayosso-Lucano BIO 1140

As industrialization and urbanization increased in America, plants, animals and humans became endangered by the rise in temperatures and carbon levels. It was then that Carla, a carbon atom was born at the Sahara desert. At night, Carla and her friends went outside to watch the stars peacefully. It had never occurred to them that the night would bring a sudden kidnap. All of Carla’s friends and Carla were attached to two oxygen atoms. Unfortunately, Carla fainted during the kidnap so when she woke up, she took the surprise of no longer being carbon but carbon dioxide. Carla then turned around and saw that her friends were equally shocked. When all of them tried to come up with an explanation of what had just occurred, they felt a strong pull. This pull came from Cactus pear Opuntia Ficus-indica. Opuntia was ready to perform photosynthesis and nothing was going to stop her from using the friends of Carla and Carla. Without hope, Carla and her friends were unable to escape the cactus desires.
Photosynthesis in Opuntia does not work the same way as in C3 plants because Opuntia is a CAM plant. Opuntia lives in a deserted region where it is hot and dry. Thus, Opuntia wants to conserve as much water as it can. To achieve this, the C4 pathway and the Calvin cycle take place at two temporal parts. In the mesophyll cell, at the C4 pathway carbon dioxide is hydrated to form bicarbonate ion, which reacts with enzyme, phosphoenolpyruvate, to produce the four-carbon compound, oxaloacetate. This process occurs at night when the stomata of the cactus are open and CO2 (Carla) was diffused in. Oxaloacetate is then reduced to malate, which is stored as malic acid in the vacuole. However, during the daytime malic acid is turned back into malate and is broken down to pyruvate and CO2. Exhausted, Carla complains on the purpose for traveling to different locations. Poor Carla, she doesn’t know that she is not even half way through her journey

    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…

    As stated in the intro photosynthesis, “is the process is where plants use “light energy from the sun that is converted into carbon dioxide and water to glucose sugar and oxygen gas through a series of reactions.” ("Chemical Formula Basic Chemistry - Writing Chemical Formula To Balancing Chemical Equations", 2014) All of this information is complied in an equation that helps understand the process, carbon dioxide + water = light energy => glucose + oxygen. The carbon dioxide can be found in the air, water comes from the earth and the energy comes from the sun. Chloroplasts trap the light energy, water then enters the leaves from the earth, and the carbon dioxide enters from the stomata. All of these combined produce glucose and oxygen, which then leaves the leaf and is stored in the plant tissue.…

    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…

    In plant cells, during photosynthesis, enzymes are used in chloroplast to catalyse the processes. In light-dependent stage, ATP synthase enzyme is used to generate ATP molecules, they can be used in light-independent stage. Another enzyme, RuBisCo , catalyse the formation of glycerate-3-phosphate in Calvin cycle. The ATP generated in light-dependent stage and NADPH then react with glycerate-3-phosphate to produce triose phosphate, useful 6C sugar therefore is formed, for the growth of plants.…

    Background Information (Activity A): In photosynthesis, plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds. It is an endergonic and anaerobic reaction. Critical to the process is chlorophyll, the primary photosynthetic pigment in chloroplasts. The chemical equation for photosynthesis is: 36 ATP + 6CO2 + 6H2O C6H12O6 + O2 (From: "LabBench for Lab 4." LabBench. PHS School, n.d.

    Photosynthesis is essential for almost all living things on earth. It is clear that all life forms depend on sunlight for energy to live, to grow, to move, to gather food and to reproduce. Without the sun there would be no life as we know it and because animals have no method for harnessing energy directly from the sun, they rely on the production of carbohydrates in plants. Apart from absorption of heat, photosynthesis is the only way in which the natural environment can absorb soloar energy and use it to convert it into energy. In the process of photosynthesis, chlorophyll absorbs the energy from the suns rays to convert into oxygen and carbohydrates which is crucial for all animals to survive. These carbohydrates are considered to be high energy compounds because when they react (respiration or combustion) they release large amounts of energy.…

    The Light Independent Reactions, also known as the Calvin Cycle and or the “dark cycle”, ATP and NADPH produce high energy sugars. To begin the cycle, six CO2 molecules enter from the atmosphere and combine with six 5-carbon molecules to form twelve 3-carbon molecules. Next, these are converted into higher energy forms using ATP and high energy electrons from NADPH. Lastly, two of the twelve 3-carbon molecules are removed from the cycle, used by the plant for metabolism and growth; the remaining ten are converted back into six 5-carbon molecules, which ultimately begin the next cycle.…

    Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. It produces sugar and other organic compounds such as lipids and proteins. The sugars are then used to provide energy for the organism. Light reaction is the series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments; such as chlorophyll, to be converted into chemical energy in the form of ATP and NADPH. Light reactions occur mostly in the thylakoid stacks of the grana. The light-independent reactions, is a light-independent series of reactions which occur in the stroma of the chloroplasts, when the products of the light reaction, ATP and NADPH, are used to make carbohydrates from carbon dioxide ( Light intensity and Wavelength). The light-dependent reaction, in this case would be the ATP Energy from light is like a forcing of electrons to flow from water to NADP in the chloroplast. The electrons retain energy in the NADPH. Some of the NADPH is used to synthesize ATP. NADPH and ATP are the products of the light reactions of photosynthesis.…
