Which is true of the metabolic pathway shown here? enzyme 1 enzyme 2 enzyme 3 a > b > c > d?

Answer;

B is the product of enzyme 1 and the substrate for enzyme 2.

Explanation;

-Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy.

-The molecules upon which enzymes may act are called substrates and the enzyme converts the substrates into different molecules known as products.

the fossil record provides evidence of a common ancestor to many species.
