Choose INCORRECT statement from the following

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. The rates of enzymatically catalyzed reactions are typically 106 to 1012 times greater than those of the corresponding uncatalyzed reactions

  2. The catalytic activities of many enzymes vary in response to the concentrations of substances other than their substrates.

  3. When the reaction involves two molecules, such as the association reaction P + Là PL, it is called second order, and its rate constant (ka) has units of M-2 s-1

  4. When the reaction involves one molecule, such as the dissociation reaction PL à P + L, the reaction is first order and the rate constant (kd) has units of (s-1).
