Which one of the following types of phosphorylation occurs in electron transport chain, when NADH transfer electrons to coenzyme Q in inner mitochondrial membrane?

Correct answer: C. Oxidative Phosphorylation

  • A. Cyclic Phosphorylation
  • B. Non-cyclic Phosphorylation
  • C. Oxidative Phosphorylation
  • D. Substrate level Phosphorylation

Explanation

ATP generation in the mitochondria's electron transport chain, where electrons move through complexes, ultimately combining with oxygen to form water is called oxidative phosphorylation.

About Bioenergetics

Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
