  1. Question 1

    Q1. A particular enzyme has a Km of 0.1 mM and a Vmax of 100 μmol/min. What is the substrate concentration at which the enzyme reaches half of its maximum velocity?

    • A) 0.01 mM
    • B) 0.1 mM
    • C) 1 mM
    • D) 10 mM

    Answer: 0.1 mM

    Explanation: Km is the substrate concentration at which enzyme reaches half of Vmax, most tempting wrong is 0.01 mM
