The starting molecule for glycolysis is glucose. Glucose is a simple sugar that enters the glycolysis pathway to be broken down into smaller molecules, generating energy through a series of chemical reactions.
Two molecules of ATP are needed to start the process of glycolysis. These ATP molecules are used to prime the glucose molecule for further breakdown and energy production.
Glucose is the substance needed to begin glycolysis. Glycolysis is the first step in the process of cellular respiration and it breaks down glucose into pyruvate to produce ATP.
The molecule needed to start glycolysis is glucose. Glucose is a simple sugar that serves as the initial substrate for the glycolytic pathway, which then breaks down glucose into smaller molecules to produce energy in the form of ATP.
One molecule of adenosine triphosphate (ATP) is typically needed to jump start glycolysis by phosphorylating glucose to form glucose-6-phosphate. This step primes glucose for further breakdown in glycolysis.

Glucose is the substance needed to begin glycolysis. Glycolysis is the first step in the process of cellular respiration and it breaks down glucose into pyruvate to produce ATP.
The starting products of glycolysis are glucose and 2 ATP molecules.
Glycolysis: A cell can harvest energy from food by cellular respiration. Both start with the same first step: the process of glycolysis which is the breakdown or splitting of glucose (6 carbons) into two 3-carbon molecules called pyruvic acid. The energy from other sugars, such as fructose, is also harvested using this process. Glycolysis is probably the oldest known way of producing ATP. There is evidence that the process of glycolysis predates the existence of O2 in the Earth's atmosphere and organelles in cells: * Glycolysis does not need oxygen as part of any of its chemical reactions. It serves as a first step in a variety of both aerobic and anaerobic energy-harvesting reactions. * Glycolysis happens in the cytoplasm of cells, not in some specialized organelle. * Glycolysis is the one metabolic pathway found in all living organisms.

Glucose-->Pyruvate(2x)
During glycolysis, the conversion of glucose to pyruvate generates a total of 4 ATP molecules. However, it requires 2 ATP molecules to initiate the process, resulting in a net gain of only 2 ATP molecules. This occurs because energy is both consumed and produced at various steps of the glycolytic pathway.
