enzymes

• What factors in relation to enzyme functioning in effects enzyme productio?

  Temperature and pH
• How does temperature affect the rate of enzyme-controlled reactions?

  • Rate increases with temperature due to higher kinetic energy
  • Rate drops after about 37°C due to enzyme denaturation
  • Enzymes denature around 45°C, causing permanent damage
• At what temperature does the rate of enzyme-controlled reactions start to drop rapidly?

  About 37°C
• What happens to enzymes at high temperatures?

  High temperatures break bonds holding enzymes together, changing the active site shape
• What is the term used when an enzyme can no longer bind to its substrate due to shape change?

  Denatured
• What is the optimum temperature for enzymes mentioned in the video?

  37°C
• What is the relationship between pH and enzyme activity?

  • pH affects enzyme activity similarly to temperature
  • Extreme pH levels can denature enzymes
  • Optimal pH varies by enzyme; most human enzymes work best at pH 7
• What is the optimal pH for most enzymes in the human body?

  About 7
• What is the optimal pH for enzymes that work in the stomach?

  About 2
• What happens to the active site of an enzyme when the pH is too high or too low?

  The active site changes shape, affecting substrate binding
