Because enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They also perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin.
SUBSTRATE
ENZYME
Dad, why is this enzyme necessary in the process?
SUBSTRATE
ENZYME
I think we're missing something
I think it's how are we going to fit the subtrate
SUBSTRATE
ENZYME
Thanks son, I remember now, we need vitamins or minerals in order to fit the substrate
What are those anyways, dad?
Vitamins and Minerals fall under two categories: The cofactors and coenzymes. Cofactors are non-protein chemical compounds or metallic ions that are required for an enzyme's role as a catalysts while coenzymes are organic molecules cofactors
SUBSTRATE
ENZYME
Ohh, so cofactors/coenzymes are necessary for some enzymes
