Which of the following describes the mechanism of an enzyme? a. enzymes reduce the activation energy of the transition state. b. enzymes require a metal to coordinate with the reactants. c. enzymes always function at low ph. d. enzymes modify the products to shift the equilibrium.

The correct answer is A.Enzymes reduce the activation energy of the transition state. I just did it. Enzymes are catalysts and will lower activation energy.

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!

if you need further assistance, let me know: )
