What substances are protein monomers? When proteins and carbohydrates are oxidized, the same amount

What substances are protein monomers? When proteins and carbohydrates are oxidized, the same amount of engheria is released. Why does the body only use proteins as a last resort as a source of energy?

Proteins are organic substances that make up any living cell. These are biopolymers, the monomers of which are amino acids.

The cell uses them as a source of energy in the last place because:

oxidation of carbohydrates is faster;
proteins perform more important functions – transport, structural, enzymatic, regulatory, signaling, contractile, protective.
Proteins are oxidized when they can no longer perform their function or when the supply of carbohydrates and fats is exhausted.
