Step 1: Understand what enzymes are. Enzymes are proteins that help speed up chemical reactions in the body.
Step 2: Learn about factors that affect enzyme activity. These include temperature, pH (acidity or alkalinity), and substrate concentration (the amount of substance the enzyme acts on).
Step 3: Identify the factor that does NOT affect enzyme activity. In this case, it is the color of the enzyme.
Step 4: Conclude that while temperature, pH, and substrate concentration can change how well an enzyme works, the color of the enzyme has no impact on its function.
