How many carbon atoms are fed into the citric acid cycle as a result of the oxidation of one molecule of pyruv

Question

a. 10

b. 8

c. 4

d. 6

e. 2

Answer 1

E. 2

2 carbon atoms are left after pyruvate oxidation, and they, then, enter the citric acid cycle. The 2 carbon atoms are called acetyl group by the way.

Answer 2

I believe for every molecule of puruvate there are 2 carbon atoms in the molecule and one of co-enzyme A. Therefore the answer is 2 carbon atoms are fed into the Krebs Cycle( citric acid cycle) by the oxidation of Pyruvate. LOL dont forget to rate me plzzz 10, xD. Hope this helps.

See the source below how Pyruvate Acid is converted to Pyruvate.

Answer 3

E.

Pyruvic acid is 3C. In the little transition stage that happens after glycolysis and before the citric acid cycle one CO2 is given off from each pyruvic acid. So a 2C molecule enters the cycle.

Answer 4

(a million)3 acetyl coA (2) (3) c) 6 (4)2 oxidative phosphorylation in cellular respiratory (5)a) 4 (6)4 mitochondrial intermembrane area (7)3 alleviation of pyruvate to sort lactate
