Answer

D

Explanation

(D)
1. In both lactic acid and alcohol fermentation not much energy is released, less that 7 percent of the energy in glucose is released out and not all of it is trapped in high energy bonds.
2. Yeast poison themselves to death when the concentra- tion of alcohol reaches about 13 percent.
3. The complete oxidation of pyruvate by the stepwise removal of all the hydrogen atoms, leaving 3 mol- ecules of `CO_(2)`.
4. During the conversion of pyruvic acid to acetyl `CoA`, 1 molecule of NADH are produced from the metabo- hsm of one molecule of pyruvic acid.
