Photosynthesis Review

Front

What is the pigment in chloroplasts that performs photosynthesis?

Back

Chlorophyll is the pigment responsible for capturing light energy in chloroplasts during photosynthesis.

Front

What are the products of the light reactions of photosynthesis that are utilized in the Calvin cycle?

Back

ATP and NADPH are the products of the light reactions that are used in the Calvin cycle.

Front

What is the primary function of the Calvin cycle?

Back

The primary function of the Calvin cycle is to produce simple sugars from carbon dioxide.

Front

What substances are directly involved in chemosynthesis?

Back

Chemosynthesis involves carbon dioxide, hydrogen sulfide, and ammonia.

Front

Can many ecosystems be sustained by chemosynthesis that starts at underwater thermal vents?

Back

True, many ecosystems can be sustained by chemosynthesis at underwater thermal vents.

Front

What is 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 Calvin cycle.

Front

Where do the light reactions of photosynthesis occur?

Back

The light reactions occur in the thylakoid membranes of chloroplasts.

Front

What is the role of water in photosynthesis?

Back

Water is split during the light reactions to provide electrons and protons, and oxygen is released as a byproduct.

Front

What is the significance of ATP and NADPH in photosynthesis?

Back

ATP and NADPH provide the energy and reducing power, respectively, needed for the Calvin cycle to synthesize glucose.
