Shyanne Cox · Answer 1

Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme

Explanation:

Enzyme are biological catalysts.

So they do alter the path of the reaction where the free energy change (or activation energy) is low then the non enzymatic pathway.

Thus the statement

Enzymes alter the free energy change (ΔG) of the reactions which they catalyze : True

It is known that for enzyme we function they need an optimum temperature and pH condition so the statement

Enzyme function is dependent on the pH and temperature of the reaction environment: true

This is also true that

Enzyme activity can be inhibited if the enzyme is bound by a noncompetitive inhibitor.

The false statement is : Enzyme function is dependent on the three-dimensional structure or conformation of the enzyme
