Which molecule can be made from acetyl CoA molecules?
Pyruvate
Which molecule is common to catabolism of fat and glucose?
Catabolism is the breakdown of molecules into smaller units. The molecule that is common to the catabolism of fat and glucose is known as acetyl CoA.
How many molecules of acetyl-CoA are produced in the catabolism of one molecule of stearic acid?
9
What are the products of acetyl CoA formation from a molecule of pyruvate?
You gain 1 NADH and acetyl CoA during the conversion of 1 pyruvate to acetyl CoA.
How many acetyl CoA molecules may be obtained from oxidation of a 16-carbon fatty acid?
A fatty acid that contains 20 carbons will yield 10 molecules of acetyl-CoA. Acetyl-CoA is also referred to as acetyl coenzyme A.
Which molecule can be made from acetyl CoA molecules?
Pyruvate
How many Acetyl coenzyme A molecules are generated from one molecule of glucose?
2: Two molecules of acetyl CoA molecules are produced by one glucose molecule, since each full round of the citric acid cycle yields one, and it takes 2 full completions because glucose yields two pyruvates. (:

How many molecules of acetyl-CoA are produced in the catabolism of one molecule of stearic acid?
9
What is the name of the molecule that pyruvates are changed into during pyruvates processing?
Acetyl CoA
What number of carbon atoms are in acetyl CoA?
23. 2 are from the acetyl group and 21 are from coenzyme A.
What are the products of acetyl CoA formation from a molecule of pyruvate?
You gain 1 NADH and acetyl CoA during the conversion of 1 pyruvate to acetyl CoA.
Calculate the number of acetyl-SCoA molecules generated by complete B-oxidation of a 12-carbon activated fatty acid?
The answer is 5. An acetyl group (containing two C atoms) is split off the original fatty acyl-SCoA with each repetition of the beta-oxidation spiral. Therefore, the first repetition of the beta-oxidation yields one acetyl-SCoA molecule and a fatty acyl-SCoA molecule that is two carbon atoms shorter than the initial fatty acyl-SCoA. There will be five acetyl-SCoA molecules produced by the fifth repetition.
How many co2 molecules are generated from each pyruvate that enter the mitochondrion?
In the decarboxylation of Pyruvate to form Acetyl CoA, one Carbon atom is lost as co2. Acetyl CoA can then be used in the citric acid cycle in which another two co2 molecules are produced. It is important to note however, that neither Pyruvate nor Acetyl CoA will necessarily follow this pathway, since they are also required for various other processes.
How many acetyl CoA molecules may be obtained from oxidation of a 16-carbon fatty acid?
A fatty acid that contains 20 carbons will yield 10 molecules of acetyl-CoA. Acetyl-CoA is also referred to as acetyl coenzyme A.
What are the Products of the Krebs cycle per molecule of pyruvate?
For one molecule of Pyruvate (pyruvic acid) the Krebs cycle produces 2 molecules of carbon dioxide (CO2), 3 molecules of NADH, one molecule of FADH2, and one molecule of ATP.Also, the change from pyruvate to acetyl CoA produces one NADH and one carbon dioxide molecule; CoA is recycled in and out of the cycle.
What is acetyl CoA and what does it combine?
Its a molecule and it combines carbon.
