AP Bio Photosynthesis

Front

What is the electron transport chain?

Back

A series of electron carrier proteins that transfer electrons during the light reactions of photosynthesis.

Front

What role does ATP Synthase play in photosynthesis?

Back

ATP Synthase is a membrane protein that allows hydrogen ions to escape the thylakoid, facilitating the production of ATP.

Front

Where do the light reactions occur in the chloroplast?

Back

The light reactions occur in the thylakoid membrane.

Front

Where do the dark reactions (Calvin cycle) take place?

Back

The dark reactions take place in the stroma of the chloroplast.

Front

What is released as a by-product of splitting water molecules during photosynthesis?

Back

Oxygen is released as a direct by-product of splitting water molecules.

Front

What would happen if the proton (H+) pump in the thylakoid was not functioning?

Back

If the proton pump was not working, ATP could not be produced during the light reactions.

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light reactions and the dark reactions (Calvin cycle).

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, responsible for capturing light energy.

Front

What is the function of NADP+ in photosynthesis?

Back

NADP+ acts as an electron carrier, accepting electrons during the light reactions to form NADPH.
