Molecular oxygen

The fate of pyruvate produced during glycolysis depends primarily on the availability of molecular oxygen.

What is glycolysis?

  • Glycolysis is a cytoplasmic mechanism that converts glucose into two molecules with three carbons each and releases energy.
  • Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose.
  • This reaction uses adenosine triphosphate (ATP), and the end result, glucose-6-P, inhibits hexokinase.

What happens during glycolysis?

  • The process by which glucose is broken down to provide energy is known as glycolysis.
  • It generates two pyruvate molecules, ATP, NADH, and water.

Importance of glycolysis:

  • Because it is the metabolic process by which glucose produces cellular energy, glycolysis is significant.
  • The most crucial source of energy for all living things is glucose.
  • Most cells in the human body prefer glucose as a fuel because red blood cells cannot use anything else.
