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…

1 Two critical ingredients required for cellular respiration are glucose and oxygen. Cellular Respiration, process in which cells produce the energy they need to survive. In cellular respiration, cells use oxygen to break down the sugar glucose and store its energy in molecules of adenosine triphosphate (ATP). Cellular respiration is critical for the survival of most organisms because the energy in glucose cannot be used by cells until it is stored in ATP. Cells use ATP to power virtually all of their activities—to grow, divide, replace worn out cell parts, and execute many other tasks. Cellular respiration provides the energy required for an amoeba to glide toward food, the Venus fly trap to capture its prey, or the ballet dancer to execute…

The volume of a single drop of three different liquids was determined by indirect measurement. This was done by counting the number of drops of the liquid that it took to fill a 10 ml graduated cylinder. The overall volume (10 ml) could then be divided by total amount of drops of each liquid which yields the volume of a single drop.…

Glucose, or any carbon-based molecule, can be burned in oxygen (oxidized) to produce carbon dioxide and water. Combustion reactions release large amounts of energy. However, the energy release is uncontrolled. An organism would not be able to handle all that energy at once to do the work of the cell. Cellular respiration is essentially the same reaction as combustion, but the oxidation of glucose occurs in several controlled steps. The same amount of energy is ultimately released, but it is gradually released in small, controlled amounts. High potential energy molecules of ATP are produced while the carbon atoms are used to form various other molecules of lower potential energy. Each of these steps is catalyzed by an enzyme specific to that step. Model 1 illustrates the ideal circumstances for cellular respiration. In some situations, however, one glucose molecule may not result in 38 ATP molecules being…

The carbon cycle is a biogeochemical cycle that displays how carbon circulates throughout the environment. Many components affect this process such as photosynthesis and cellular respiration. Photosynthesis uses the carbon dioxide that is in the atmosphere to transform it into sugar and oxygen; cellular respiration puts carbon dioxide in the air. Both of these processes were studied during the experiment. In the experiment, the tube with both the elodea and the snail had the same level of carbon dioxide in both the light and dark tube. This occurred because the snail performed cellular respiration, and the elodea performed both photosynthesis and cellular respiration. In the light, the solution was a yellow green, and in the dark, the solution was a yellow green. From this experiment, there is some carbon dioxide present when an organism that performs both cellular respiration and photosynthesis and another organism that performs only cellular respiration are paired together.…
