Photosynthesis

Front

What pigment absorbs sunlight for photosynthesis?

Back

Chlorophyll is the pigment that absorbs sunlight for photosynthesis.

Front

Why do most plants appear green?

Back

Most plants appear green because chlorophyll reflects green light.

Front

Where do the light-dependent reactions of photosynthesis occur?

Back

The light-dependent reactions occur in the thylakoid membrane.

Front

What substance from the light-dependent reactions is a source of energy for the Calvin Cycle?

Back

NADPH is the substance from the light-dependent reactions that provides energy for the Calvin Cycle.

Front

Which molecule is more like a fully charged battery, ADP or ATP?

Back

ATP is more like a fully charged battery because it has three phosphate groups; breaking and reforming the bonds among them releases energy.

Front

What is the primary function of chlorophyll in photosynthesis?

Back

The primary function of chlorophyll in photosynthesis is to capture light energy.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin Cycle).

Front

What is produced during the light-dependent reactions?

Back

During the light-dependent reactions, ATP and NADPH are produced.

Front

What is the role of water in photosynthesis?

Back

Water provides electrons and protons during the light-dependent reactions and is split to release oxygen.

Front

What is the overall equation for photosynthesis?

Back

The overall equation for photosynthesis is 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
