23. 2 are from the acetyl group and 21 are from coenzyme A.
23 carbon atoms are present in Acetyl-CoA, but there are only 2 in the acetyl group which are "relevant" to most reactions.
The molecular formula of acetyl CoA isC23H38N7O17P3S and it has 23 carbon atoms in one molecule
One in -C=O group

Its a molecule and it combines carbon.
In eukaryotic cells, acetyl CoA is produced in the mitochondria from molecules derived from sugars and fats.
Acetyl CoA
Pyruvate is converted to acetyl-CoA before entering the Krebs cycle.
Acetyl CoA is the compound that enters the Kreb's cycle.
Acetyl CoA
Its a molecule and it combines carbon.
In eukaryotic cells, acetyl CoA is produced in the mitochondria from molecules derived from sugars and fats.
A fatty acid that contains 20 carbons will yield 10 molecules of acetyl-CoA. Acetyl-CoA is also referred to as acetyl coenzyme A.
It is true that the compound that joins with a 4-carbon molecule in the krebs cycle is called acetyl-CoA. It is also known as Acetyl coenzyme A.
Acetyl CoA
It splits into a two-carbon acetyl group, which is added to Coenzyme A to make Acetyl-CoA, and a CO2.
Pyruvate is converted to acetyl-CoA before entering the Krebs cycle.
Acetyl CoA is the compound that enters the Kreb's cycle.
Krebs cycle
If by "first carbon" you mean the first CO2 released in the cycle then the answer is, from OAA. NOT from acetyl CoA.
You gain 1 NADH and acetyl CoA during the conversion of 1 pyruvate to acetyl CoA.
