Definition:
The breakdown of glucose by enzymes, releasing energy and pyruvic acid.
Step 1:
Hexokinase breaks a phosphate off of an ATP, this ATP becomes ADP. This phosphate is added to the sixth Carbon of Glucose, which is Glucose-6-phosphate.
Step 2:
phosphoglucoisomerase isomerizes the Glucose-6-phosphate to turn it into Fructose-6-phosphate.
Step 3:
Phosphofructokinase breaks a phosphate off of another ATP. Phosphate attaches to sugar molecule and is now Fructose-1,6-biphosphate.
Stage 4:
Adolase splits this molecule UNEVENLY.
Stage 5:
Makes Glyceraldehyde-3-phosphate(G3P) and Dihydroxyacetone phosphate(DHP). DHP very unstable and is converted into G3P by isomerase immediately.
Stage 6:
Both G3P's: Glyceraldehyde-3-phosphate. Dehydrogenase rips hydrogens off of 3GPs and the 2 hydrogens are added to both NADs(NADs are reduced). There are now two 1,3-biphosphoglycerate.
Stage 7:
Phosphoglyceromutase removes a phosphate from each 1,3-biphosphoglycerate. These are added to ADPs, making 2 ATPs. Makes 2 3-phosphoglycerate.
Stage 8:
Phosphoglyceromutase shifts phosphate. Now there are two 2-phosphoglycerate.
Stage 9:
Enolase removes 2 H2O to make 2 Phosphoenolypurate(PEP)
Stage 10:
Pyruvatekinase removes phosphate from each making 2 ATPs. Molecules are now Pyruvate(CH3)
