Hint: The breaking of a glucose molecule into three-carbon compounds either by releasing or consuming ATP.

Complete answer:
Glycolysis is the metabolic pathway which means lysis or breakdown of sugar or glucose molecules.
Glycolysis is the pathway in which one molecule of glucose is converted into two molecules of pyruvate or pyruvic acid through different series of steps.

Additional information
1) Glycolysis is an anaerobic pathway consisting of ten steps.
2) It takes place in the cytoplasm and can take place without oxygen.
3) It is also called the Embden Meyerhof Parnas (EMP) Pathway.
4) The net end products of glycolysis are two pyruvate molecules, two molecules of reduced coenzyme NADH, and two ATP.
5) Glycolysis is the first main metabolic pathway of cellular respiration to produce energy in the form of ATP.
6) There are two distinct phases in which a six-carbon ring of glucose is cleaved into two three-carbon sugars of pyruvate through a series of enzymatic reactions.
7) It occurs in both eukaryotic and prokaryotic cells.
8) Glycolysis is important in the cell because glucose is the main source of fuel or energy for tissues in the body.

So, the correct answer is Pyruvic acid.

Note: The pyruvate of glycolysis enters the Krebs cycle for further energy production. Kreb cycle is the series of chemical reactions in most aerobic organisms to release stored energy.
