Document Summary
Thus when substrate molecules bind to this region, they are brought into close proximity with each other. This enables collisions interactions between the substrate molecules to be more frequent and more active than if they were flowing around freely in the reaction mixture. G* is the minimum amount of energy required to bring all the molecules in. 1 mol of reactant to the transition state or activation complex where the probability is high that complex would break down to form products. Enzyme displays absolute specificity for glucose (i. e. , will act only on glucose as substrate: hexokinase will phosphorylate all hexose to form the corresponding sugar products. Hexokinase exhibits group specificity because it acts on a group of closely related molecules (in this case hexose sugars) Stereospecific enzyme act on only one member of a set of optical isomers of some compound. E. g. , may act on d-amino acids or l-amino acids but not both.
