MCAT Question of the Day


  • Q:

    The steps of the net enzymatic reaction Substrate (S) ↔ Product (P) can be written as follows, where E represents the enzyme:

    E + S ↔ ES ↔ EP ↔ E + P

    In most enzymatic reactions, the rate-limiting step is the binding of the substrate to the enzyme. This suggests the rate law of the overall reaction S ↔ P can be written as:


     

    A

    rate = k[E][S]

    B

    rate = k[ES]

    C

    rate = k[E][P]

    D

    The answer cannot be determined from the given information.
