Final answer:
Enzymes help with the digestion of food by breaking down large molecules into smaller ones. Enzyme function is regulated by cofactors and coenzymes, which are supplied through the diet. Vitamins act as coenzymes for certain enzymes.
Step-by-step explanation:
Enzymes play an important role in the digestion of food. They help break down large molecules of carbohydrates, proteins, and fats into smaller molecules that can be used by the body. Without enzymes, animals would not be able to process food quickly enough to obtain the energy and nutrients they need to survive.
Enzyme function is also regulated by the abundance of cofactors and coenzymes, which are supplied by the diet. For example, vitamins act as coenzymes for certain enzymes, allowing them to function correctly.
