Photosynthesis

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll

Front

What are the two main stages of photosynthesis?

Back

Light reactions and the Calvin cycle

Front

Where do the light reactions of photosynthesis occur?

Back

In the thylakoid membranes of chloroplasts

Front

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

Back

Oxygen

Front

What is the role of NADP+ in photosynthesis?

Back

NADP+ acts as an electron carrier, becoming reduced to NADPH during the light reactions.

Front

What is the main purpose of the Calvin cycle?

Back

To convert carbon dioxide into glucose using ATP and NADPH.

Front

What is chemiosmosis in the context of photosynthesis?

Back

Chemiosmosis is the process by which ATP is produced as hydrogen ions flow back across the thylakoid membrane through ATP synthase.

Front

What is the significance of the stroma in photosynthesis?

Back

The stroma is the site of the Calvin cycle, where carbon fixation occurs.

Front

What is an endergonic reaction?

Back

An endergonic reaction is a chemical reaction that requires an input of energy to proceed.
