Using a real-world analogy, how can the proportional decrease in apparent Km and Vmax by uncompetitive inhibitors be explained?

• A. Like a teacher (inhibitor) who only helps students (substrates) already working with a tutor (enzyme), slowing down the overall learning (reaction rate).
• B. Like a race where more competitors (substrates) lead to a faster finish (reaction rate).
• C. Like a traffic jam where more cars (substrates) lead to faster travel (reaction rate).
• D. Like a chef (enzyme) who can cook faster with more ingredients (substrates).

Answer: (A)
