AP Biology Photosynthesis

Front

What is the goal of photosynthesis?

Back

The goal of photosynthesis is to convert light energy into glucose energy.

Front

What is produced during the light reactions of photosynthesis?

Back

The light reactions produce NADPH and ATP.

Front

What are the reactants used in the light reactions of photosynthesis?

Back

The reactants used in the light reactions are water and NADP+.

Front

What is the primary function of the light reactions?

Back

The primary function of the light reactions is to produce NADPH and ATP.

Front

What is released as a by-product of photosynthesis?

Back

Oxygen is released as a by-product of photosynthesis.

Front

What is the role of water in photosynthesis?

Back

Water is split to provide electrons and protons, releasing oxygen in the process.

Front

What is ATP and why is it important in photosynthesis?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, produced during the light reactions.

Front

What is NADPH and its role in photosynthesis?

Back

NADPH is an electron carrier that provides reducing power for the Calvin cycle.

Front

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

Back

The hydrogen ion gradient is used to generate ATP through chemiosmosis.

Front

What is chemiosmosis in the context of photosynthesis?

Back

Chemiosmosis is the process of using a hydrogen ion gradient to synthesize ATP.
