Reaction of Glycolysis
1.A phosphate group is transferred to glucose from ATP
,forming glucose 6 phosphate
-
- A second phosphate group is added to give fructose 1,6 -disphosphate
4.The 6-carbon sugar fructose is split into 2 different 3-carbon sugar which is dihydroxyacetone phosphate and glyceraldehyde 3-phosphate
- Dihydroxyacetone phosphate is rearrange to form a second molecule of glyceraldehyde 3-phosphate
6.Another phosphate group is added , and 2 hydrogen atoms with their electrons are transferred to NAD, forming 1,3-biphosphoglycerate
- A phosphate group is transferred to ADP, forming ATP,3-phosphoglycerate is produced
8.The remaining phosfate group is moved from the end to the middle carbon atom ,to form phosphoglycerate
-
10.The phosphate group is transferred to ADP forming more ATP producing pyruvic asid.Glycolysis is complete.
GLUCOSE
-
FERMENTATION
-
Result of the need to recycle the limited amount of NAD by passing the electrons of reduced NAD off to other molecules
Important Pathway
HOMOLATIC ACID FERMENTATION
-
Pryruvic acid is directly converted to lactic acid,using electrons from reduced NAD
Lactic Acid is made, produces no gas
-
-
ALCOHOLIC FERMENTATION
Carbon dioxide is released from pyruvic acid to form intermediate acetyldehyde,which is quickly reduced to ethyl alcohol by electrons from reduced NAD
