Explanation

The Krebs cycle is also called the citric acid cycle because citric acid (citrate) is the first intermediate formed in the cycle. It's also known as the TCA (tricarboxylic acid) cycle. It's the central metabolic pathway that generates energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.
