Answer:
The correct answer will be- Protons pumped by the NADH through inner mitochondrial membrane is greater than the protons pumped by the FADH₂.
Explanation:
During the cellular respiration, the electron donors like NADH and FADH₂ are produced which donates the electrons during the electron transport chain.
The NADH molecule contains high energy electron which transmits the electron to complex I. This releases a large amount of energy utilized to pump H⁺ ions from matrix to intermembrane space.
Similarly, the FADH₂ contains low energy electrons as compared to the NADH so fewer protons are pumped to intermembrane space.
Since NADH pumps a large number of protons that is 10 protons whereas FADH₂ pumps only 6 protons and four protons are required to form the ATP therefore, NADH produces about 2.5 ATP whereas FADH₂ forms 1.5 ATP.
Thus, Protons pumped by the NADH through the inner mitochondrial membrane is greater than the protons pumped by the FADH₂ is the correct answer.
Muscles require a large amount of energy to function. This is provided primarily by mitochondria in cells that consume a lot of energy. We therefore find more of these powerhouses of the cell in muscle cells than in other cell types with a lower metabolic rate.

Answer:
A. INACTIVE PRECURSOR OF THE ENZYME PEPSIN THAT DIGESTS PROTEINS IN THE STOMACH.
Explanation:
Pepsinogen is the inactive precursor of pepsin produced by the chief cells of the stomach lining. The stomach walls are lined by majorly two types of cells; the chief and the parietal cells. Chief cells secretes pepisinogen and parietal cells secrete hydrochloric acid in the stomach lining. The chief cells upon the signals of increased protein substance in the stomach produces pepsinogen which upon it release, it is activated to the active enzyme Pepsin by the hydrochloric acid from the parietal cell. Hydrochloric acid provides the acidic environment needed for the action of pepsin in the stomach. The pepsin begins the digestion of proteins into small amino acids in the stomach,
