Ch.4 Photosynthesis test

Front

What supplies the electrons during photolysis?

Back

Water supplies the electrons during photolysis.

Front

How many molecules of ATP are needed for each 'turn' of the Calvin cycle?

Back

Eighteen ATP molecules are needed for each turn of the Calvin cycle.

Front

Which molecule acts as the final electron acceptor in the light-dependent reactions?

Back

NADP+ acts as the final electron acceptor in the light-dependent reactions.

Front

Where do the light-independent reactions occur?

Back

The light-independent reactions occur in the stroma of the chloroplast.

Front

What is an electron carrier?

Back

An electron carrier is a compound that can accept and transfer high-energy electrons.

Front

What is the primary function of chlorophyll in photosynthesis?

Back

The primary function of chlorophyll is to absorb light energy for photosynthesis.

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 the role of water in photosynthesis?

Back

Water provides electrons and protons for the light-dependent reactions and is a source of oxygen.

Front

What is produced during the light-dependent reactions?

Back

The light-dependent reactions produce ATP, NADPH, and oxygen.

Front

What is the main product of the Calvin cycle?

Back

The main product of the Calvin cycle is glucose.
