Read the following statements carefully: A. Glycolysis is also known as the EMP pathway and is the only process in respiration for anaerobic organisms. B. The enzyme pyruvate dehydrogenase requires Mg ²⁺ for the oxidative decarboxylation of pyruvate. C. The TCA cycle starts with the condensation of an acetyl group with citric acid to yield oxaloacetic acid. D. The formation of ATP through the electron transport syste

Options

  1. AFour
  2. BThree
  3. CTwo
  4. DOne

Correct answer

B. Three

Step-by-step solution

Statement A is correct: The scheme of glycolysis was given by Embden, Meyerhof, and Parnas (EMP pathway) and it is the only respiration process in anaerobic organisms. Statement B is correct: The oxidative decarboxylation of pyruvate to acetyl CoA is catalysed by pyruvate dehydrogenase, which requires Mg ²⁺ along with NAD ⁺ and CoA. Statement C is incorrect: The TCA cycle starts with the condensation of an acetyl group with oxaloacetic acid (OAA) and water to yield citric acid, not the reverse. Statement D is corre
