Photosynthesis - AP Biology

Front

What are the main products of the light reactions of photosynthesis?

Back

ATP and NADPH are the main products of the light reactions.

Front

What is the role of ATP in the Calvin Cycle?

Back

ATP provides the energy needed for the conversion of CO2 into glucose during the Calvin Cycle.

Front

What is the role of NADPH in the Calvin Cycle?

Back

NADPH provides the reducing power (electrons) needed to convert CO2 into glucose during the Calvin Cycle.

Front

What is the function of the proton pump in the thylakoid membrane?

Back

The proton pump helps create a hydrogen ion gradient that is used to produce ATP during the light reactions.

Front

What happens to NADP+ during the light reactions?

Back

NADP+ is reduced to NADPH during the light reactions.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is a series of biochemical reactions that take place in the stroma of chloroplasts, where CO2 is fixed and converted into glucose.

Front

Which molecule is not required for the Calvin Cycle?

Back

H2O is not required for the Calvin Cycle.

Front

What is the significance of the hydrogen ion gradient in photosynthesis?

Back

The hydrogen ion gradient is essential for ATP synthesis during the light reactions.

Front

What is the primary source of energy for photosynthesis?

Back

The primary source of energy for photosynthesis is sunlight.

Front

What is the overall equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.
