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.
