Correct Answer � C
Explanation
|
|
Ans.C. Van der Waals forces arise from attractions between transient dipoles generated by the rapid movement of electrons of all neutral atoms. Significantly weaker than hydrogen bonds but potentially extremely numerous, van der Waals forces decrease as the sixth power of the distance separating atoms. Thus, they act over very short distances, typically 2 to 4 Å.
Van der Waals force is very weak. So not involved in the formation of the enzyme-substrate complex.
