Step-by-step explanation:
There are 4 main types of macromolecules: lipids, proteins, carbohydrates, and nucleic acids.
If you are looking for some quick energy, the best choice is carbohydrates. Carbohydrates are the easiest for the body to break down and turn into ATP/energy.
There are also different types of carbohydrates. If you want a more specific answer, monosaccharides is the best answer. They are the simplest sugars. Also, glucose is a monosaccharide, and it shows up directly in the cellular respiration formula. If glucose is consumed, the body doesn't have to break it down before starting respiration.
