After glucose-6-p what does it convert to?
|
|
Glucose
|
|
|
Pyruvate
|
|
|
Enolase
|
|
|
Fructose-6-p
|
Explanation:
Detailed explanation-1: -Glucose-6-phosphate (G6P) is changed into fructose-6-phosphate (F6P) by phosphoglucoisomerase (phosphoglucose isomerase) in the second step. This reaction also requires Mg2+. F6P can enter the glycolytic pathway from the next point.
Detailed explanation-2: -When Glucose-6-phosphate is converted to Fructose-6-phosphate, this process is known as isomerization. In this reaction, one molecule is converted to another molecule which exactly has the same atoms.
Detailed explanation-3: -The great majority of glucose is converted to fructose 6-phosphate upon entering a cell.
