which are true regarding metabolism?
□ it includes reactions where new molecules are synthesized.
□ it includes reactions where molecules are broken down.
□ it consists entirely of endergonic reactions that require an input of energy.
□ it only takes place in muscle cells.
□ it can be defined as the sum of all of the chemical reactions in the body.

Explanation:

Metabolism is the sum of all chemical reactions in the body. It has two main types: anabolism (synthesis of new molecules) and catabolism (break - down of molecules). It includes both endergonic (energy - requiring) and exergonic (energy - releasing) reactions and occurs in all cells, not just muscle cells.

Answer:

It includes reactions where new molecules are synthesized.
It includes reactions where molecules are broken down.
It can be defined as the sum of all of the chemical reactions in the body.
