What is the role of coenzyme a?
a) it gets broken down to make atp
b) it gets attached to a two carbon molecule
c) it is an enzyme that breaks down pyruvate
d) it is an enzyme that will break down acetyl
e) none of the above

B) It gets attached to a two carbon molecule

Explanation:

Oxidative decarboxylation of pyruvate in the mitochondrial matrix produces two carbon molecule. This two carbon molecule is attached to CoA and acetyl CoA is formed. Coenzyme A (CoA) gets attached to the acetyl group via its thiol group and serves as acyl carrier for the first reaction of Kreb's cycle.

The acetyl CoA then enters the Kreb's cycle and is completely broken down into CO2 and H2O.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
