Photosynthesis Review

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

What is the primary function of cyclic electron flow?

• to produce additional NADPH
• to produce additional ATP
• to produce additional oxygen
• to produce additional carbon dioxide

In a plant cell, where are ATP synthase complexes located?

• thylakoid membranes only
• inner mitochondrial membranes only
• thylakoid membrane and inner mitochondrial membranes
• thylakoid membrane and plasma membranes

Where are the molecules of the electron transport chain associated with photophosphorylation located in plant cells?

• thylakoid membanes of chloroplasts
• stroma of chloroplasts
• matrix of mitochondria
• outer membrane of chloroplasts

What is the primary function of the Calvin cycle?

• regenerate ATP for use in the light reactions of photosynthesis
