Questions and Answers

Which component is responsible for the reduction of NADP to NADPH2 in photosynthesis?

  • Protons (H+)
  • Cyclic electron flow
  • NADH
  • Electrons from split water molecules (correct)

    • What is the main difference concerning the reaction centers in cyclic and non-cyclic photophosphorylation?

  • Cyclic photophosphorylation uses P700 while non-cyclic photophosphorylation uses P680 (correct)
  • Both use the same reaction center, P700
  • Both use the same reaction center, P680
  • Cyclic photophosphorylation uses P680 while non-cyclic photophosphorylation uses P700

    • Which type of photophosphorylation involves both photosystem I and II, and results in the production of both ATP and NADPH molecules?

  • Cyclic photophosphorylation
  • Neither cyclic nor non-cyclic photophosphorylation
  • Non-cyclic photophosphorylation (correct)
  • Both cyclic and non-cyclic photophosphorylation
