AP Biology Photosynthesis Flashcard

Front

What is the electron transport chain?

Back

A series of protein complexes and other molecules that transfer electrons through a membrane within mitochondria or chloroplasts, leading to the production of ATP.

Front

What is regeneration in the Calvin Cycle?

Back

The process where energy and sugar interact to form the molecule RuBP, allowing the cycle to start again.

Front

What is the function of NADP+ in photosynthesis?

Back

NADP+ acts as an electron carrier, transporting electrons from the light reactions to the Calvin Cycle.

Front

What is the Calvin Cycle?

Back

A series of biochemical reactions that take place in the stroma of chloroplasts, where carbon dioxide is fixed and converted into glucose.

Front

How are cellular respiration and photosynthesis related?

Back

The energy captured in photosynthesis is used to power cellular respiration, creating a cycle of energy transformation.

Front

What is the role of rubisco in photosynthesis?

Back

Rubisco is an enzyme that catalyzes the first step of the Calvin Cycle, incorporating CO2 into RuBP.

Front

What are thylakoids?

Back

Membrane-bound compartments inside chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is ATP and its role in photosynthesis?

Back

Adenosine triphosphate (ATP) is the energy currency of the cell, produced during the light reactions and used in the Calvin Cycle.

Front

What is the significance of light in photosynthesis?

Back

Light provides the energy needed to drive the light-dependent reactions, leading to the production of ATP and NADPH.

Front

What is photolysis?

Back

The process of splitting water molecules using light energy during the light-dependent reactions of photosynthesis.
