If you are in Biology this is probably a good thing to know.
Glycolysis is the stage of respiration that does not require oxygen to make ATP, Adenosine Tri-phosphate, the energy source for every organism on this Earth.
Steps:
1. Glucose enters the mitochondria by having ATP bond it to a phosphate molecule, this is called phosphorolization. The glucose becomes glucose phosphate and the ATP becomes ADP, adenosine di-phosphate, Then an enzyme changes it to Fructose Phosphate. Another ATP molecule changes the Fructose Phosphate into Fructose Diphosphate by giving it a phosphate molecule. This phase is called the active energy phase.
2.Fructose Diphospate is extremely unstable and splits in half as soon as it is formed becoming two molecules of PGAL,Phosphoglyceraldahyde, the PGAL is then phosphorolized by a free phosphate molecule releasing two hydrogens that are picked up by an NAD molecule. The NAD becomes NADH2 and is used in a later process. PGAL becomes DPGA, Diphospoglyceric Acid.
3. DPGA breaks down releasing enough energy to phosporolize one ADP molecule to create an ATP molecule. DPGA then becomes PGA.
4.PGA then loses a water molecule and becomes a PEP molucule,Phosphonel pyruvate, a highly entergetic molecule that phosphorolizes another ADP molecule and then regains its water and becomes Pyruvi Acid.
This reaction happens with both of the PGAL molecules produced by Fructose Diphosphate spliting
The products of this process are:
2 pyruvic Acids
2 NADH2
4 ATP molecules
