Which organic acid is produced at the end of the TCA cycle?

Step-by-step solution

The TCA (Tricarboxylic Acid) cycle, also known as the Krebs cycle, is a series of chemical reactions used by all aerobic organisms to release stored energy. The cycle begins with the condensation of acetyl-CoA with oxaloacetic acid to form citric acid. Through a series of steps involving oxidation and decarboxylation, various intermediates like -ketoglutaric acid, succinic acid, fumaric acid, and malic acid are formed. In the final step of the cycle, malic acid is oxidized by the enzyme malate dehydrogenase to rege
