[AI-generated answer — Explain Bot]

To determine which type of biomolecule provides the greatest energy per gram through oxidation, we need to compare the energy yields of protein, lipid, carbohydrate, and nucleic acid.

The energy yield of a biomolecule can be measured in terms of the number of calories it provides per gram during oxidation. This value, known as the caloric value or energy density, varies depending on the specific biomolecule.

Here are the approximate energy yields (in calories per gram) for each type of biomolecule:

a. Protein: 4 calories per gram
b. Lipid (fat): 9 calories per gram
c. Carbohydrate: 4 calories per gram
d. Nucleic acid: negligible energy release during oxidation

Based on these values, we can see that lipids (fats) provide the greatest energy per gram during oxidation, with 9 calories per gram. Lipids have the highest energy density compared to proteins and carbohydrates, making them an efficient source of energy storage in organisms. Proteins and carbohydrates both provide 4 calories per gram during oxidation.

Therefore, the correct answer is:

b. Lipid (fat)
