Importance of Glycolysis
Glycolysis is the first step in the breakdown of glucose to extract energy for cellular metabolism.
The Energy-Requiring Steps of Glycolysis
In the first half of glycolysis, energy in the form of two ATP molecules is required to transform glucose into two three-carbon molecules.
The Energy-Releasing Steps of Glycolysis
In the second half of glycolysis, energy is released in the form of 4 ATP molecules and 2 NADH molecules.
Outcomes of Glycolysis
One glucose molecule produces four ATP, two NADH, and two pyruvate molecules during glycolysis.
