Biology II Honors Photosynthesis NEW

Front

Where do the light-dependent reactions occur in photosynthesis?

Back

The light-dependent reactions occur in the thylakoid membrane.

Front

Where do the light-independent reactions (Calvin cycle) take place?

Back

The light-independent reactions take place in the stroma.

Front

What are the main reactants used in the light reactions of photosynthesis?

Back

Water and NADP+.

Front

What is the purpose of the H+ concentration gradient in photosynthesis?

Back

The H+ concentration gradient is used to generate ATP.

Front

What are photosystems primarily made of?

Back

Photosystems are made of chlorophyll.

Front

What is the main goal of photosynthesis?

Back

The main goal of photosynthesis is to convert light energy into glucose energy.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is essential for the light-dependent reactions.

Front

What is produced as a byproduct of the light-dependent reactions?

Back

Oxygen gas (O2) is produced as a byproduct.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent reaction that converts carbon dioxide into glucose using ATP and NADPH.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to help convert carbon dioxide into glucose.
