Question

the graphs below show reaction vs temperature and the rate of reaction vs ph for an enzyme. which statement provides the correct interpretation of the graphs? a the enzyme works best at a certain temperature and is not affected by changes in ph. b the enzyme works best at a certain ph and is not affected by changes in temperature. c the enzyme works best within specific ranges of temperature and ph. d the enzyme works well no matter how the temperature or ph changes.

Explanation:

Step1: Analyze enzyme - environment relationship

Enzymes are biological catalysts. Their activity is affected by environmental factors like temperature and pH. Each enzyme has an optimal temperature and pH range where it functions best.

Step2: Evaluate each option

• Option A: Enzymes are affected by both temperature and pH. So, this option is incorrect.
• Option B: Enzymes are affected by temperature. So, this option is incorrect.
• Option C: Enzymes work best within specific ranges of temperature and pH. This is correct as enzymes have optimal conditions for activity.
• Option D: Enzymes are affected by temperature and pH changes. So, this option is incorrect.

Answer:

C. The enzyme works best within specific ranges of temperature and pH.
