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.
