Question

Can you guys help me, please

Why is it necessary for living organisms to have enzymes to speed up chemical reactions?

Answer 1

Digestive enzymes speedup reactions that break down large molecules of carbohydrates, proteins, and fats into smaller molecules the body can use. Without digestive enzymes, animals would not be able to break down food molecules quickly enough to provide the energy and nutrients they need to survive.

Answer 2

enzymes are biocatalysts made up of proteins which increases the rate of bio chemical reaction by lowering down the activation energy

Step-by-step explanation:

since activation energy of the chemical reaction gets lowered by enzymes as a result it speed up the process of metabolism in living organism
