Photosynthesis A

Which of the following are products of the light reactions of photosynthesis that are utilized in the Calvin cycle?

• CO2 and glucose
• H2O and O2
• electrons and H+
• ATP and NADPH

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

Which of the following is directly associated with Photosystem I?

• harvesting light energy to make ATP
• receiving electrons from the thylakoid membrane ETC
• generation of molecular oxygen
• extraction of hydrogen electrons from the splitting of water

In photosynthetic cells, synthesis of ATP by chemiosmosis occurs during

• photosynthesis only
• cellular respiration only
• both photosynthesis and cellular respiration
• photophosphorylation only

What is the primary function of the Calvin cycle?

• regenerate ATP for use in the light reactions of photosynthesis
