Photosynthesis AP Biology

Front

What is the primary goal of photosynthesis?

Back

To convert light energy into glucose energy.

Front

Which factor has the least effect on the rate of photosynthesis?

Back

Increasing the amount of O2 from 20% to 30% in the air.

Front

Why does cyclic photophosphorylation occur during the light reactions?

Back

Because the Calvin cycle runs out of ATP.

Front

What reactants do plants use for the light reactions of photosynthesis?

Back

Water and NADP+.

Front

What is the effect of increased CO2 levels in the air on photosynthesis?

Back

It would most likely increase photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

Light reactions and the Calvin cycle.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to drive the photosynthetic process.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is photorespiration and how does it affect photosynthesis?

Back

Photorespiration is a process that consumes O2 and releases CO2, reducing the efficiency of photosynthesis.

Front

What is the significance of the stomata in photosynthesis?

Back

Stomata are openings on the leaf surface that allow CO2 to enter and O2 to exit.
