ATP and Photosynthesis: Practice Test

Front

How many G3P molecules make one molecule of glucose?

Back

2 G3P molecules are required to make one molecule of glucose.

Front

What results in the storage of energy in terms of the ATP/ADP cycle?

Back

The addition of a phosphate group to ADP forms ATP, storing energy.

Front

During which reaction of photosynthesis is water split to replace the electrons on chlorophyll?

Back

Water is split during the Light Dependent reactions.

Front

Which bond of the ATP molecule is broken to release energy?

Back

The bond between the second and third phosphate groups (Bond A) is broken to release energy.

Front

What happens to the remaining (5) G3P molecules in the last step of the Calvin Cycle?

Back

They are reshuffled to make RuBP by adding ATP.

Front

What is ATP?

Back

ATP (Adenosine Triphosphate) is the energy currency of the cell.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants convert light energy into chemical energy.

Front

What are the two main stages of photosynthesis?

Back

The two main stages are the Light Dependent reactions and the Light Independent reactions (Calvin Cycle).

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, which is used to split water and energize electrons.

Front

What is G3P?

Back

G3P (Glyceraldehyde-3-phosphate) is a three-carbon sugar produced in the Calvin Cycle.
