Biology Photosynthesis

Where does the Calvin cycle take place?

• stroma of the chloroplast

• thylakoid membrane

• outer membrane of the chloroplast

• interior of the thylakoid membrane

When oxygen is released as a result of photosynthesis, it is a direct by-product of

• reducing NADP+

• splitting water molecules

• chemiosmosis

• electron transfer in photosystem II and I

What is the primary function of the Calvin cycle?

• regenerate ATP for use in the light reactions of photosynthesis
• produce carbon dioxide for use in the light reactions of photosynthesis
• produce oxygen by oxidizing water
• produce simple sugars from carbon dioxide
