What is the effect of pH on enzyme activity?
  1. Enzymes work best at any pH
  2. Each enzyme has an optimal pH range
  3. pH has no effect on enzyme activity
  4. All enzymes are active at neutral pH only

Questions & Step-by-Step Solutions

What is the effect of pH on enzyme activity?
  • Step 1: Understand that enzymes are proteins that help speed up chemical reactions in the body.
  • Step 2: Know that each enzyme works best at a specific pH level, called the optimal pH.
  • Step 3: Realize that if the pH is too high or too low (not in the optimal range), the enzyme's activity can decrease.
  • Step 4: Learn that extreme pH levels can cause the enzyme to change shape, a process called denaturation, which stops it from working.
