Oxidative phosphorylation pogil answers pdf

    • What is oxidative phosphorylation?

      This energyis used to phsophorylate ADP. This coupling of ATP synthesis to NADH/FADH2 oxidation is called oxidative phosphorylation. Oxidative phosphorylation is responsible for 90 % of total ATP synthesis in the cell. The chemiosmotic theory explains the mechanism of oxidative phosphorylation.

    • How many ATP molecules are produced during oxidative phosphorylation?

      Under ideal conditions each NADH molecule will result in three ATP molecules, and each FADH molecule will result in two ATP molecules during oxidative phosphorylation. Calculate the total number of ATP molecules that might be produced in this phase of cellular respiration from one glucose molecule. 14.

    • Do uncouplers inhibit oxidative phosphorylation?

      Uncouplers inhibit oxidative phosphorylation. They ‘uncouple’ the ETC from oxidative phosphorylation. The ETC remains intact and electrons are transferred to O 2 to generate H 2O. However, uncouplers carry protons across the mitochondrial membrane making it ‘leaky’ for H+. The pH and electrical gradient is not generated and ATP is not synthesized.

    • How is glycerol 3 phosphate oxidated back to DHAP?

      The oxidation of glycerol 3-phosphate back to DHAP is catalyzed by a mitochondrial membrane bound isoenzyme of glycerol-3-phosphate dehydrogenase. The oxidation is coupled to reduction of a FAD prosthetic group of the mitochondrial enzyme to FADH2. Reduced FADH2 transfers it electrons to CoQ via the ETC.

      Oxidative phosphorylation is the process by which energy from electron transport chain is used to make ATP, and is the culmination of energy yielding metabolism in aerobic organisms. Oxidative phosphorylation involves the reduction of O2 to H2O with electrons donated by NADH and FADH2, and equally occurs in light or darkness.
