Question

Catabolism generally starts with what kind of molecules?

Answer 1

Catabolism generally starts with larger molecules such as carbohydrates, lipids, and proteins, which are broken down into smaller molecules.

Step-by-step explanation:

Catabolism generally starts with larger molecules such as carbohydrates, lipids, and proteins, which are broken down into smaller molecules. These smaller molecules can then be used by the body to assemble structures and substances needed for life. For example, carbohydrates can be broken down into simple sugars, fats can be broken down into fatty acids and glycerol, and proteins can be broken down into amino acids.
