Embden-Meyerhof-Parnas pathway

Definition

The Embden-Meyerhof-Parnas (EMP) pathway, also known as glycolysis, is a series of enzymatic reactions that convert glucose into pyruvate, generating ATP and NADH in the process. This pathway is fundamental for energy production in both aerobic and anaerobic organisms.

5 Must Know Facts For Your Next Test

1. The EMP pathway occurs in the cytoplasm of cells.
2. It consists of ten steps divided into two phases: the preparatory phase and the payoff phase.
3. During glycolysis, one molecule of glucose is converted into two molecules of pyruvate.
4. The pathway produces a net gain of 2 ATP molecules and 2 NADH molecules per glucose molecule.
5. Glycolysis does not require oxygen and can function under anaerobic conditions.
