In a metabolic pathway, substrate Z is broken down to form products Y and X. Y is further broken down into products V and W. How many enzymes are required for this metabolic pathway?

There are 2 enzimes required for this metabolic pathway.

Explanation:

In living beings, enzymes act specifically on a substrate with which they have affinity.

In the aforementioned problem, there is an enzymatic reaction on two substrates to form products, therefore, there are 2 enzymes acting on said substrates.
