Question

Quizplus · Accepted Answer

Glucose is the most commonly used source of energy by cells. It is a simple sugar that can be easily broken down through cellular respiration to produce ATP, the main energy currency of the cell. Fatty acids and proteins can also be used for energy, but glucose is the preferred choice as it is more efficient and produces fewer harmful byproducts. Sucrose is a type of carbohydrate that needs to be broken down into glucose and fructose before it can be used as an energy source by cells.
