Question

which substances can be metabolized to yield energy that human cells use to perform work? proteins fats carbohydrates vitamins alcohol minerals yield energy do not yield energy

Explanation:

Proteins, fats, carbohydrates, and alcohol can be metabolized to yield energy. Proteins are broken down into amino acids, fats into fatty acids and glycerol, carbohydrates into simple sugars (like glucose), and alcohol (ethanol) through specific metabolic pathways. Vitamins and minerals are essential for various bodily functions but do not directly provide energy when metabolized.

Answer:

Yield Energy: Proteins, Fats, Carbohydrates, Alcohol
Do Not Yield Energy: Vitamins, Minerals
