Describe how enzymes affect chemical reactions and explain why this makes enzymes important to living thing

Answer; and explanation;

-Enzymes are proteins that control the speed of chemical reactions in the body. Without enzymes, these reactions would take place too slowly to keep one alive. Some enzymes, like the ones in the gut, break down large molecules into smaller ones.

Enzymes are catalysts for chemical reactions in living things. Enzymes, like other catalysts, lower the activation energy and increase the rate of chemical reactions.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
