Answer:
To store the energy released during redox reactions in form of NADH and FADH2 to maximize the ATP production from overall process of aerobic cellular respiration.
Step-by-step explanation:
Kreb's cycle is the second stage of aerobic cellular respiration in which pyruvate enters as acetyl-CoA. The function of the Krebs cycle is complex oxidation of acetyl-CoA into CO2 and to store the released energy in the form of reducing powers NADH and FADH2.
Oxidation of NADH and FADH2 during oxidative phosphorylation generates proton motive force which drives the synthesis of a large number of ATPs.
