What would happen if enzymes didn't regulate chemical traffic through pathways of metabolism?

Metabolic processes will become uncontrolled.

Explanation:

Enzymes play very essential role in metabolic processes. They transfer electrons from one molecule to another and assist as cell in regulating the extent of anabolic and catabolic processes taking place with in a cell. Thus, if enzymes stops functioning or stop regulating the chemical traffic through pathways of metabolism then the metabolic processes will either not start and in case if they already started, then will not inhibit and remain in the stage of continuation.

b - the respond is innate and varies over time.

good luck!
