In order for cells to get energy they must break down sugar called glucose. Glycolysis leads to the formation of ATP, a form of available energy used for cellular activity.
Steps of Glycolysis
2 phosphates are donated to a glucose molecule by 2 ATP molecules
The new 6-carbon sugar diphosphate molecule is split into two 3-carbon sugar phosphate molecules
2 NAD's are reduced and two phosphate groups are added to each 3-carbon sugar phosphate molecule
The phosphates attached to the 3-carbon sugar phosphate molecules are donated to existing ADP molecules in order to form ATP molecules and two 3-carbon pyruvate molecules known as pyruvic acid..
Glycolysis produces a net gain of 2 ATP molecules,
producing more energy than is required for the process to occur.
