বহুনির্বাচনি (MCQ)
১. In competitive enzyme inhibition:
ক) Km decreases and Vmax decreases
খ) Km increases and Vmax is unchanged
গ) Km is unchanged and Vmax decreases
ঘ) Both Km and Vmax increase
ঙ) The inhibitor binds an allosteric site

সঠিক উত্তর: খ) Km increases and Vmax is unchanged
ব্যাখ্যা: A competitive inhibitor competes for the active site; raising substrate concentration overcomes it, so Vmax is unchanged while apparent Km rises. Non-competitive inhibition lowers Vmax with Km unchanged.
