Detailed explanation-1: -The mitochondrial matrix contains a large variety of enzymes, including those that convert pyruvate and fatty acids to acetyl CoA and those that oxidize this acetyl CoA to CO2through the citric acid cycle. Large amounts of NADH (and FADH2) are produced by these oxidation reactions.
Detailed explanation-2: -Electron Transport System (ETS) and Oxidative Phosphorylation.
Detailed explanation-3: -Option C: The inner membrane is highly convoluted to increase the surface area for ATP production. It has a series of infoldings called cristae. This statement is also correct about mitochondria.
Detailed explanation-4: -The mitochondria DNA is circular and devoid of histone proteins, unlike the DNA present in the nucleus which is linear and is wound around a histone protein core. The mitochondrial DNA is a double-stranded molecule. Was this answer helpful?
