36. Which of the following statement regarding glycolysis is true?
 1. Hexokinase undergo a distinct conformational change when it binds glucose.
 2. The phosphorylation of glucose to glucose 6-phosphate is an exergonic reaction that iscoupled to the endergonic hydrolysis of ATP.
 3. The binding of glucose to hexokinase is an example of induced-fit binding of a substrateto the active site of an enzyme.
 4. The phosphorylation of fructose 6-phosphate to fructose-1,6-bisphosphate is thecommitted step in glycolysis because it is the most strongly exergonic step in thepathway.
