Saturated fatty acids store more energy than unsaturated fatty acids. Based on your knowledge of aerobic respiration, you draw this conclusion because saturated fatty acids
A) lack phosphate.
B) are deaminated.
C) contain more ATP.
D) are more highly reduced.
E) contain more ester linkages.

Question

Quizplus · Accepted Answer

Saturated fatty acids are more highly reduced compared to unsaturated fatty acids, meaning they have more hydrogen atoms per carbon atom. This results in a higher potential energy content, as each bond broken during aerobic respiration releases energy. Unsaturated fats have one or more double bonds, which means they have fewer hydrogen atoms for each carbon atom, thus storing less energy.
