Question
Which of the following best describes the nature of enzymes?ANon-protein, non-specific biological catalystsBNon-protein, specific biological catalystsCProtein, non-specific biological catalystsDProtein, specific biological catalysts
Solution
The best description for the nature of enzymes is D: Protein, specific biological catalysts.
Here's why:
Enzymes are biological catalysts, which means they speed up chemical reactions in living organisms. They are made up of proteins, which contradicts options A and B.
Furthermore, enzymes are specific because they can only catalyze certain reactions. Each enzyme has a unique shape that fits the molecule(s) it acts on, like a lock and key. This specificity contradicts option C.
Therefore, the correct answer is D: Protein, specific biological catalysts.
