Which of the following statements about β-oxidation of fatty acids is CORRECT? A. Thiolytic cleavage releases acetyl-CoA and a free fatty acid in the final step of the cycle.
B. Both dehydrogenation reactions use FAD as the electron acceptor.
C. Both dehydrogenation reactions produce a C=C double bond.
D. Fatty acids of any length are oxidized by exactly the same enzymes.
E. All fatty acids must be activated to acyl-CoAs before entering the pathway.

C

Explanation:

since the dehydrogenation reacts n produces a c=C w a bond that is doubled lol

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: )
