The oxidation - reduction substances which take part in respiratory chain are following EXCEPT:

Correct answer: D. Cytochrome f

  • A. Coenzyme Q
  • B. Molecular oxygen
  • C. Cytochromes b, c, a and a3
  • D. Cytochrome f

Explanation

Cytochrome f is a protein involved in photosynthesis and is not part of the respiratory chain. It functions as an electron carrier in the electron transport chain of photosystem I in photosynthetic organisms, such as cyanobacteria and algae.

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.
