Question 3

Which of the following statements correctly describe(s) the metabolic relationships between photosynthesis and aerobic respiration in a photosynthetic plant cell?

  1. Oxygen (O2O_2O2​) produced during the photolysis of water in the thylakoids can be utilized as the terminal electron acceptor in oxidative phosphorylation within the mitochondria.
  2. Reduced NADP (NADPHNADPHNADPH) produced during the light-dependent stage of photosynthesis can be directly oxidized by the mitochondrial electron transport chain to generate ATP.
  3. Carbon dioxide (CO2CO_2CO2​) released during decarboxylation reactions in the mitochondrial matrix can be used as a substrate for carbon fixation in the chloroplast stroma.
