Calvin Cycle Quiz

What is the initial molecule that carbon dioxide attaches to in the Calvin cycle?

• Glyceraldehyde 3-phosphate (G3P)

• ATP

• Ribulose bisphosphate (RuBP)

• Glucose

Which phase of the Calvin cycle involves the use of ATP to convert 3-phosphoglycerate into 1,3-bisphosphoglycerate?

• Reduction Phase

• Carbon Fixation Phase

• Photorespiration

• Regeneration Phase

During the reduction phase, what molecule is formed from 1,3-bisphosphoglycerate?

• Carbon dioxide

• Ribulose bisphosphate (RuBP)

• Glucose

• Glyceraldehyde 3-phosphate (G3P)

How many G3P molecules are used to regenerate RuBP in the Calvin cycle?

• One

• Six

• Three

• Five

What is the primary purpose of the regeneration phase in the Calvin cycle?

• To regenerate RuBP

• To fix carbon dioxide

• To generate ATP

• To produce glucose
