Photosynthesis

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

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 thylakoid membrane ETC

• generation of molecular oxygen

• extraction of hydrogen electrons from the splitting of water

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

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

• produce carbon dioxide for use in the light reactions of photosynthesis

• produce oxygen by oxidizing water

• produce simple sugars from carbon dioxide

Which of the following is the correct equation for PHOTOSYNTHESIS?

• CO₂ + light + H₂O --> O₂ + Sugar

• CO₂ + sugar + H₂O --> O₂ + light

• _O2 + light + H₂O --> CO₂ + Sugar

• CO₂ + O₂ + H₂O --> Light+ Sugar
