Question

Quizplus · Accepted Answer

Triacylglycerol, also known as fat, is the largest reserve of potential metabolic energy in humans. It provides more than twice the amount of energy per gram compared to carbohydrates (glucose and glycogen) or protein. While liver and muscle glycogen stores can provide energy for a few hours of activity, the fat stores in adipose tissue can provide energy for weeks or months.
