Enzymes bind to a substrate and a chemical reaction, resulting in a desirable product. Enzymes increase the rate of nearly all chemical reactions in living cells.

Catalyze

Explanation:

Catalysis is defined as the acceleration the of the rate of a chemical reaction, enzymes are natural catalysts that can make more efficient, faster reactions by using less energy and generating less waste.

I hope you find this information useful and interesting! Good luck!

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
