The answer is D. Just think how hard it would be to see a moth of that colour when just about everything during that time period is grey.
The body converts simple sugars into glucose
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
B. the bond forms when electrons are shared
