Question

the reactions of human metabolism utilize the______energy that is stored in carbohydrates, lipids, proteins, and alcohol. multiple choice nuclear mechanical chemical heat

Explanation:

Carbohydrates, lipids, proteins, and alcohol store energy in chemical bonds. Human metabolism breaks these bonds to release energy. Nuclear energy involves atomic nuclei (not relevant here). Mechanical energy is related to motion (not stored in these molecules). Heat is a form of energy release but not the stored form. Chemical energy is the energy stored in chemical bonds of substances like carbohydrates, lipids, proteins, and alcohol, which is utilized in metabolic reactions.

Answer:

chemical
