[Cell Respiration]



Glycolysis is the first step of reactions that break glucose apart to liberate the energy it holds in its C-H bonds.

Glycolysis occurs in the cell cytoplasm.

As a set of reactions, Glycolysis does not need the presence of oxygen.

Glycolysis occurs in both aerobic (with oxygen) and anerobic (does not need oxygen) respiration!

Summary of Glycolysis
1. One glucose (6C) converted into 2 pyruvates (3C).
2. Net yield of 2 ATP for use by cell.
3. 2 NADH are made. (These carry energy & Hydrogen to Electron Transport.)
