Know why it is advantageous to have hexokinase phosphorylate glucose. - Answer-Hexokinase has a random Bi Bi mechanism where the two substrates and two products can bind and leave in any order. HK phosphorylates 6 carbon sugars, prevents sugars from leaving the cell. This step doesn't always have ...
