Question

Which of the following statements is NOT correct about glycolysis?

• A. Glycolysis takes place within the cytoplasm
• B. Glycolysis uses two ATP but forms four ATP, resulting in a net gain of two ATP molecules
• C. During glycolysis, two NADH are produced as substrate oxidation occurs
• D. Glycolysis begins with glucose and ends with four pyruvate molecules

Answer 1

The correct option is B

Glycolysis uses two ATP but forms four ATP, resulting in a net gain of two ATP molecules

Glycolysis is the first step of cellular respiration which takes place in the cytoplasm. In this process, glucose is broken down to form pyruvate. Pyruvate enters Krebs cycle for further breakdown.
