Detailed explanation-1: -The key enzymes involved are: (A) pyruvate dehydrogenase; (B) citrate synthase; (C) isocitrate dehydrogenase; (D) -ketoglutarate dehydrogenase and succinyl-CoA synthetase; (E) succinic dehydrogenase; (F) fumarase; (G) malate dehydrogenase.
Detailed explanation-2: -Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome. They also divide independently of the cell in which they reside, meaning mitochondrial replication is not coupled to cell division.
Detailed explanation-3: -Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
