Photosynthesis and the Calvin Cycle Quiz

What is the primary function of the Calvin cycle in photosynthesis?

• To release oxygen as a byproduct

• To fix carbon dioxide into a stable form

• To convert light energy into chemical energy

• To absorb water and nutrients

Why is the term 'light-independent reactions' misleading when referring to the Calvin cycle?

• Because it produces light as a byproduct

• Because it depends on the products of light-dependent reactions

• Because it does not require any energy

• Because it occurs only in the presence of light

Where does the Calvin cycle take place within the chloroplast?

• In the thylakoid membrane

• In the stroma

• In the outer membrane

• In the cytoplasm

What molecule is regenerated at the end of each Calvin cycle to allow the process to continue?

• Glucose

• ATP

• NADPH

• Ribulose bisphosphate (RuBP)

How many carbon dioxide molecules are incorporated into the Calvin cycle during each turn?

• Two

• Four

• One

• Three
