Calvin cycle

CAM plants reduce water loss by only opening their stomata at night.

How do CAM plants reduce water loss?

Carbon Fixation

The incorporation of C02 into organic compounds.

The Calvin cycle takes gaseous CO2 and converts it into glucose to store energy captured during the light reactions.

What is the overall purpose of the Calvin Cycle? How does it connect with the light reactions of photosynthesis?

Light plateaus because the maximum number of excited electrons has been reached. If electrons cannot become excited, the rate of photosynthesis cannot increase. Carbon dioxide plateaus because the maximum number of enzymes is being used.

Why do some of the reaction plateau?

Stomata

Small openings on the underside of leaves which allows CO2 to enter and O2 to leave.

Light, which increases photosynthesis until it plateaus by exciting more electrons, carbon dioxide, which increases photosynthesis until it plateaus by increasing the rate of the Calvin cycle, and Temperature, which increases photosynthesis before the stomata closes at a certain temperature and decreases after that by accelerating enzymes and stopping enzymes from working respectively.

What are the 3 factors that affect the rate of photosynthesis? How does each affect photosynthesis and why?

Reactants: CO2, ATP, NADPH Products: 3-PGA, G3P, carbohydrates (glucose), RuBP

What are the reactants and the products of the Calvin cycle?
