Q. Most of the biological energy is supplied by mitochondria through

A) Breaking of proteins
B) Reduction of $NADP^{+}$
C) Breaking of sugars
D) Oxidising TCA (tricarboxylic acid) substrate
Explanation

In TCA cycle TCA substrate oxidise by releasing $NADH\ + \ H^{+}$, which produces three ATP molecules. So, one glucose molecule through TCA produces $6\ NADH\ + \ H^{+}$. So 18 ATP produced through electron transport chain. 2 $FADH_{2}$ of Kreb’s cycle produced 4 ATP
