What do we know about the consumption of an enzyme during a metabolic reaction in the body?

Answer;

Enzymes are not consumed in a chemical reaction

Explanation;

Enzymes are biochemical catalysts that speed up chemical reactions. These biochemical catalysts combine with substrate to form an enzyme-substrate complex where the substrate undergoes catalysis to form a product.During the metabolic reactions enzymes are not consumed or altered with, which means they remain unchanged. They only functions to speed up the reaction or the speed or the rate at which the products are formed from the reactants.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

Ithink is a because if say increased in electronegativity
