How many carbons are there in an acetyl coA?
A
2
B
3
C
4
D
6
Explanation: 

Detailed explanation-1: -Thus, each molecule of Acetyl CoA has two carbon atoms.

Detailed explanation-2: -Description. Acetyl Coenzyme A is the condensation product of coenzyme A and acetic acid which participates in the biosynthesis of fatty acids and sterols, in the oxidation of fatty acids and in the metabolism of many amino acids.

Detailed explanation-3: -The 3-carbon pyruvate molecule made in glycolysis loses a carbon to produce a new, 2-carbon molecule called acetyl CoA.

Detailed explanation-4: -Amino acids: Acetyl-CoA is generated during the catabolism of isoleucine, leucine, and threonine. Lysine and tryptophan each generate two acetyl-CoA molecules. Metabolism of cysteine, alanine, and tryptophan generates pyruvate, which may be converted into acetyl-CoA.

Detailed explanation-5: -Each Acetyl CoA consists of 2 carbon atoms.
