|
Glycolysis |
This metabolic pathway includes: Occurs in the cytosol of cell Nets 2 molecules of ATP Converts a molecule of glucose into 2 molecules of pyruvate acid and provides hydrogen ions to electron carriers for ETS in the form of 2 NADH molecules |
|
TCA cycle (krebs' or citric cycle) |
This occurs in mitochondrial matrix Produces 2 ATP Provides hydrogen ions for electron carriers for ETS in the form of NADH and FADH2 molecules Produces carbon dioxide as waste |
