The net gain of energy from one molecule of glucose during aerobic respiration in prokaryotes is

Explanation

During aerobic respiration in prokaryotes, one molecule of glucose is completely oxidized through glycolysis, the citric acid cycle, and oxidative phosphorylation, resulting in a net gain of approximately 38 ATP. Glycolysis generates 2 ATP, the citric acid cycle contributes additional ATP, and the majority of ATP is produced during oxidative phosphorylation. Options A and C incorrectly represent partial processes or incorrect net gains, while Option D overestimates the ATP yield.
