Brainliestt ! 1. how does an enzyme inhibitor work? 2. how many valence electrons does carbon have? why is this important?

1.  The binding of an inhibitor can stop a substrate from entering the enzyme's active site and/or hinder the enzyme from catalyzing its reaction. Inhibitor binding is either reversible or irreversible. Irreversible inhibitors usually react with the enzyme and change it chemically (e.g. via covalent bond formation).

2. Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds.

hope this helps

the form of energy changes and the total energy increases0l
