Multiple Choice

Which of the following statements best describes the concept of induced fit in enzyme catalysis?

The enzyme and substrate both change shape to fit into each other simultaneously.

The substrate changes shape to fit into the enzyme's active site without altering the enzyme.

The enzyme's active site changes shape to better accommodate the substrate upon binding.

The enzyme's active site is rigid and does not change shape upon substrate binding.

Verified step by step guidance

Understand the concept of enzyme catalysis: Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to proceed.

Familiarize yourself with the 'lock and key' model: This model suggests that the enzyme's active site is a perfect fit for the substrate, much like a key fits into a lock. However, this model does not account for the flexibility of enzymes.

Learn about the 'induced fit' model: This model proposes that the enzyme's active site is flexible and can change shape to better fit the substrate upon binding. This flexibility allows for a more precise interaction between the enzyme and substrate.

Analyze the given statements: Compare each statement to the induced fit model. The correct statement should reflect the idea that the enzyme's active site changes shape to accommodate the substrate.

Identify the correct statement: The statement 'The enzyme's active site changes shape to better accommodate the substrate upon binding' aligns with the induced fit model, as it describes the dynamic adjustment of the enzyme to facilitate catalysis.
