Question

If one gram of each of the following were eaten as food, identify which would yield the most energy within the cell

Answer 1

The answer would be Triglyceride.

Triglycerides is a main constituent of body fat. One gram of fat will yield more than double the amount of energy that a carbohydrate and protein will yield, which means that triglyceride is the answer. (credit to the dude/girl that also answered the question)
