The proteins of the electron transport chain are located in the mitochondrial inner membrane. (Option B)

  • The mitochondria is a double membraned organelle in the cell which is the final site of metabolism for the production of energy in the form of ATP.
  • At the end of the Citric Acid Cycle/TCA cycle in the mitochondrial matrix, six molecules of NADH and two FADH2 are produced. Totally, 6+2+2 NADH from glycolysis and TCA combined, and 2 FADH2 enter the etecton transport chain.
  • Proteins in the ETC called cytochromes undergo redox reactions to convert the NADH and FADH2 molecules into ATP by maintaining a transmembrane proton gradient.
  • At the end of the ETC, 38 ATP molecules are produced.
