Final answer:
Glycolysis begins with a six-carbon glucose molecule and ends with two molecules of a three-carbon sugar called pyruvate. Glycolysis consists of two distinct phases: the first part involves making adjustments for the splitting of the glucose molecule, and the second part involves the production of ATP and NADH. energy-conservation.
Step-by-step explanation:
Glycolysis begins with the six-carbon ring-shaped structure of a single glucose molecule and ends with two molecules of a three-carbon sugar called pyruvate. Glycolysis consists of two distinct phases. In the first part of the glycolysis pathway, energy is used to make adjustments so that the six-carbon sugar molecule can be split evenly into two three-carbon pyruvate molecules. In the second part of glycolysis, ATP and NADH are produced.
