In step 4 of glycolysis, fructose-1,6-bisphosphate is split into two three carbon products. One product has an aldehyde function; the other has a ketone function. Step 5 isomerizes the ketone to the aldehyde

Circle the aldehyde group.

Steps 1 through 5 represent the first half of glycolysis. How many molecules of glyceraldehyde-3-phosphate are produced per glucose in the first half of glycolysis?

Expert Solution

Ans. #1.

#2. In step 4, 1 glucose molecule splits into 1 molecule each of G-3-P and DHAP. Since G-3-P is continuously consumed in further steps of glycolysis, DHAP is isomerized into G-3-P, too.

Therefore, 1 molecule of glucose forms a total of 2 (two) G-3-P molecules (1 G-3-P + 1 DHAP isomerized to G-3-P) in first phase of glycolysis.
