What is formed during the first step of the TCA cycle? ATP water ADP citric acid oxygen
Bot
During the first step of the Tricarboxylic Acid (TCA) cycle, also known as the Krebs cycle or citric acid cycle, citric acid (also called citrate) is formed. This occurs when acetyl-CoA combines with oxaloacetate, thanks to the enzyme citrate synthase. It is important to note that ATP, water, ADP, and oxygen are not directly formed during this step of the cycle. However, oxygen is a crucial component for the complete oxidation of glucose in the mitochondria, where the TCA cycle occurs.
