Question

In glycolysis, for each molecule of glucose oxidized to pyruvate A. 2 molecules of ATP are used and 2 molecule of ATP are produced. B. 2 molecules of ATP are used and 4 molecules of ATP are produced. C. 4 molecules of ATP are used and 2 molecules of ATP are produced. D. 2 molecules of ATP are used and 6 molecules of ATP are produced. E. 6 molecules of ATP are used and 6 molecules of ATP are produced.

Answer 1

Answer;

B. 2 molecules of ATP are used and 4 molecules of ATP are produced.

Explanation;

• Glycolysis is the first phase of ecllular respiration that converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.
• One glucose molecule produces four ATP, two NADH, and two pyruvate molecules during glycolysis.
• The net products of this process are two molecules of ATP, since four molecules of ATP are produced and 2 ATP molecul;es are used, and two molecules of NADH.
