Question

Why is kreb cycle(a step in aerobic respiration)is called terminal oxidation

Answer 1

Krebs cycle is an important series of biochemical reactions in cellular respiration. It is called as terminal oxidation because the substrate Acetyl coenzyme A is present in highly reduced form in the beginning. ( Many H atoms.) Through the course of Krebs cycle all the Hydrogen atoms are oxidized and energy is released. The final products being CO₂ and H₂O along with energy in several molecular forms.
