Detailed explanation-1: -Krebs cycle or TCA cycle takes place in the matrix of mitochondria under aerobic condition. Step 1: The first step is the condensation of acetyl CoA with 4-carbon compound oxaloacetate to form 6C citrate, coenzyme A is released. The reaction is catalysed by citrate synthase.
Detailed explanation-2: -The first step is a condensation step, combining the two-carbon acetyl group (from acetyl CoA) with a four-carbon oxaloacetate molecule to form a six-carbon molecule of citrate.
Detailed explanation-3: -The TCA cycle is also known as the Krebs Cycle (named for its discoverer, Hans Adolf Krebs) and the citric acid cycle (named after the intermediate citric acid, or citrate). The TCA cycle metabolizes acetate derived from carbohydrates, proteins, and fats to form adenosine triphosphate (ATP), the body’s energy currency.
