Question

write the reaction of glycolysis

Answer 1

The overall reaction of glycolysis which occurs in the cytoplasm is
represented simply as:

C6H12O6 + 2 NAD+ + 2 ADP + 2 P -----> 2 pyruvic acid, (CH3(C=O)COOH + 2 ATP + 2 NADH + 2 H+

At this time, concentrate on the fact that glucose with six carbons is converted into two pyruvic acid molecules with three carbons each. Only a net "visible" 2 ATP are produced from glycolysis. The 2 NADH will be considered separately later.

The major steps of glycolysis are outlined in the graphhic on the left. There are a variety of starting points for glycolysis; although, the most usual ones start with glucose or glycogen to produce glucose-6-phosphate. The starting points for other monosaccharides, galactose and fructose, are also shown.

Answer 2

Reaction of glycolysis
Reaction 1: Phosphate Ester Synthesis
   II      II     2:Isomerisation
   II      II     3:Phosphate ester synthesis
   II      II     4.Split molecule in half
   II      II     5.Isomerisation then ......
Starting with glucose-6-phosphate with 6 carbons, the final result of the glycolysis reactions is two molecules of pyruvic acid, since reaction 5-9 are each carried out twice.
Glycolysis=
C6H12O6 + 2 NAD+ + 2 ADP + 2 P -----> 2 pyruvic acid, (CH3(C=O)COOH + 2 ATP + 2 NADH + 2 H+
