Detailed explanation-1: -Glucose-6-phosphate is more reactive than glucose, and the addition of the phosphate also traps glucose inside the cell since glucose with a phosphate can’t readily cross the membrane.
Detailed explanation-2: -The addition of the second phosphoryl group to produce fructose 1, 6-bisphosphate is an irreversible step, and so is used to irreversibly target the glucose 6-phosphate breakdown to provide energy for ATP production via glycolysis.
Detailed explanation-3: -The position of the hydroxyl group has a great influence on the properties of compounds for which, alpha glucose is generally more reactive than beta glucose. It has a melting point of 146 °C and a specific rotation of 112.2°.
Detailed explanation-4: -Glycolysis produces only two net molecules of ATP per 1 molecule of glucose. However, in cells lacking mitochondria and/or adequate oxygen supply, glycolysis is the sole process by which such cells can produce ATP from glucose.
