Glycolysis |
|
| In a complex organism, the harvesting
of energy from food takes place in three stages. Glycolysis is the first
stage of cellular respiration in energy harvesting, occuring in the cytoplasm
of a cell. |
|
| Glycolysis means the "splitting of sugar".
It is a series of enzyme-catalyzed steps that breaks a 6-carbon glucose
into two 3-carbon pyruvates. This process requires 2 ATP to begin. It produces 2 NADH that will be used in the last step of the process (Electron Transport Phosphorylation), and 4 ATP (for a net gain of 2 ATP) to be used as energy. |
