Without an inhibitor an enzyme has Vmax = 100 µmol min⁻¹ and Km = 2.0 mM. With an inhibitor at 6.0 mM it has Vmax = 100 µmol min⁻¹ and an apparent Km of 5.0 mM. The inhibitor binds reversibly. Which description is correct?

Without an inhibitor an enzyme has $V_{\max} = 100\ \mu\text{mol min}^{-1}$ and $K_m = 2.0\ \text{mM}$ . With an inhibitor at $6.0\ \text{mM}$ it has $V_{\max} = 100\ \mu\text{mol min}^{-1}$ and an apparent $K_m$ of $5.0\ \text{mM}$ . The inhibitor binds reversibly. Which description is correct?

← An enzyme obeys Michaelis-Menten kinetics. Its initial rate is 30 µmol min⁻¹ at a substrate concentration of 3 mM, and 40 µmol min⁻¹ at 6 mM. Which pair of constants fits both measurements?A culture of *Escherichia coli* is diluted by a factor of 10⁶ and 0.1 mL of the dilution is spread on an agar plate, which gives 85 colonies. The cells in the culture double every 30 min and have been growing exponentially for the last 120 min at least. What was the number of viable cells per mL in the culture 120 min earlier? →
