AP Photosynthesis and Cellular Respiration

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 events occurs in the light reactions of photosynthesis?

• NADP+ is produced
• ATP is consumed to yield ADP
• carbon dioxide is fixed in organic molecules
• light is absorbed and funneled to reaction-center chlorophyll a

Which of the following is directly associated with Photosystem I?

• harvesting light energy to make ATP

• receiving electrons from the the first ETC

• generation of molecular oxygen

• extraction of hydrogen electrons from the splitting of water

In photosynthetic cells, chemiosmosis, or creating ATP by the movement of H+ moving through ATP synthase 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
• produce carbon dioxide for use in the light reactions of photosynthesis
• produce oxygen by oxidizing water
• produce simple sugars from carbon dioxide

Where do the enzymatic reactions of the Calvin cycle take place?

• stroma of the chloroplast
• thylakoid membranes
• matrix of the mitochondria
• thylakoid space

Reactions that consume CO2 take place in

• the light reactions of photosynthesis only
• the calvin cycle only
• the light reactions and the calvin cycle
• the calvin cycle and the citric acid cycle
