- Under what environmental conditions does photorespiration “outcompete" that of the CC? Specifically, what mechanism is responsible for committing the cell to photorespiration and what type of plant does not have any "safeguards" to ensure that the CC is performed rather than photorespiration?Which of the following scenarios happens during the light-dependent reaction of photosynthesis? Oxygen gas is produced in the thylakoid lumen by the oxidation of water by photosystem I. Ferrodoxin and NADP+ reductase participates in the reduction of NADP+ to NADPH. Carbon dioxide enters the plants via stomata. Rubisco attaches three molecules of ribulose bisphosphate (RuBP) to one molecule of carbon dioxide.Plants have evolved by developing mechanisms that promote entry of CO, into the Calvin Cycle (CC) to limit photorespiration when environmental conditions tend to favor the latter. This is because photorespiration 1) is energetically inefficient (consuming more ATP than the CC alone) and 2) it does not produce any sugars that can be "fed" into cellular respiration to produce lots more ATP. A) Under what environmental conditions does photorespiration "outcompete" that of the CC? Specifically, what mechanism is responsible for committing the cell to photorespiration and what type of plant does not have any "safeguards" to ensure that the CC is performed rather than photorespiration? B) Describe the mechanisms employed by two types of plants to minimize photorespiration and ensure that the CC is carried out even when environmental conditions are not in their favor. Be sure to identify 1) the type of plant, 2) its natural environment and how it affects the plant's ability to perform the CC,…

- How do C4 plants minimize photorespiration? Multiple Choice Stomata are only opened at night, storing carbon dioxide in the stroma. During the day, the carbon dioxide is released for photosynthesis. Carbon dioxide is fixed twice in different cells. The Calvin cycle occurs in the bundle sheath cells where oxygen concentrations are lower. Carbon dioxide is fixed twice in different cells so that carbon dioxide does not come into contact with rubisco. Stomata are only opened at night, storing oxygen in malate. During the day, the oxygen is released for photosynthesis. Stomata are only opened at night, storing carbon dioxide in malate. During the day, the carbon dioxide is released for photosynthesis.Explain the chemical pathway used to fix carbon dioxide in C3 plants in preparation for the Calvin cycle.
