codon chart
second base in codon

Explanation:

Step1: Analyze the enzyme - substrate diagram

In an enzyme - substrate interaction, the enzyme is the larger molecule (usually the more stable, larger - looking structure), the substrate is the molecule that binds to the enzyme, and the active site is the region on the enzyme where the substrate binds. Looking at the diagram, the green (or teal) structure (B) is the enzyme (since enzymes are the biological catalysts with a specific 3 - D structure that the substrate binds to). The pink structure (C) is the substrate (the molecule that is going to react with the enzyme). The region A is the active site, which is the part of the enzyme where the substrate binds.

Step2: Assign labels

• For part A: The active site is the region on the enzyme where the substrate binds. So A should be labeled "Active Site".
• For part B: The larger, more stable - looking structure (the green one) is the enzyme. So B should be labeled "Enzyme".
• For part C: The pink structure that is going to bind to the enzyme's active site is the substrate. So C should be labeled "Substrate".

Answer:

• A: Active Site
• B: Enzyme
• C: Substrate
