Question

In the Krebs cycle, how is citric acid formed?(2 points) Responses acetyl-CoA joins with a large molecule called oxaloacetic acid acetyl-CoA joins with a large molecule called oxaloacetic acid pyruvic acid molecules are broken down by an acetyl group pyruvic acid molecules are broken down by an acetyl group carbon dioxide bonds with a chain of coenzyme A

Answer 1

In the Krebs cycle, citric acid (also known as citrate) is formed when acetyl-CoA joins with a large molecule called oxaloacetic acid. Therefore, the correct response is:

**Acetyl-CoA joins with a large molecule called oxaloacetic acid.**
