Q. Biological oxidation in Krebs’ cycle involves
A) $O_{2}$
B) $CO_{2}$
C) $O_{3}$
D) N$O_{2}$
Explanation
Krebs’ cycle takes place in matrix of mitochondria. Largest amount of phosphate bond energy is produced in Krebs’ cycle due to oxidation by $O_{2}$. We get 6C$O_{2}$, 8NAD$H_{2}$, 2FAD$H_{2}$ and 2ATP molecules in Krebs’ cycle.
