A)glucose
B)glycogen
C)alanine
D)stearic acid
E)all of the above would have identical energy yields

Question

Quizplus · Accepted Answer

Stearic acid, being a long-chain saturated fatty acid, has the most reduced form of carbon among the options. This means it has more hydrogen-carbon bonds available to be oxidized, which yields the largest amount of energy per gram when metabolized compared to glucose (a simple sugar), glycogen (a polysaccharide form of glucose storage), and alanine (an amino acid).
