Question

Quizplus · Accepted Answer

Lipids store the most chemical energy per unit of weight. This is because lipids have more carbon-hydrogen bonds and fewer oxygen atoms compared to carbohydrates and proteins, which makes them more reduced and capable of releasing more energy when oxidized. Lipids contain 9 calories per gram, whereas carbohydrates and proteins only contain 4 calories per gram. Nucleic acids do not store energy in the same way as lipids, carbohydrates, and proteins.
