The overall process of glycolysis results in the production of Multiple Choice 1 molecule of pyruvate and 2 molecules of ATP. 2 molecules of pyruvate and 1 molecule of ATP. 1 molecule of pyruvate and 1 molecule of ATP. 2 molecules of pyruvate and 2 molecules of ATP.

2 molecules of pyruvate and 2 molecules of ATP

Explanation:

Glycolysis is a chemical reaction which occurs in the cytosol of the cell oxidizing the glucose molecule to produce ATP energy. The glycolysis reaction proceeds by the enzyme-catalyzed reaction in ten steps and is the first stage of the cellular respiration. The process of glycolysis converts the glycolysis into 2 pyruvate molecules.

The glycolysis steps are divided into two phases: the energy-requiring phase and energy-releasing phase. The energy-requiring phase requires 2 ATP whereas energy-releasing phase 4 ATP molecule and since 2 ATP are consumed therefore 2 ATP is the net gain.

Thus, 2 molecules of pyruvate and 2 molecules of ATP is correct.
