Factors that affect enzymes

• What factors affect the functioning of enzymes?

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

  Higher temperature increases reaction rate initially
• Why does the rate of reaction drop after 37°C?

  High temperatures break bonds in enzymes
• At what temperature does enzyme denaturation occur in this context?

  Around 45°C
• What is the optimum temperature for enzyme activity mentioned in the video?

  37°C
• Do different enzymes have the same optimal temperature?

  No, different enzymes have different optimal temperatures
• What does pH measure?

  Acidity
• How does pH affect enzyme activity?

  Extreme pH levels can denature enzymes
• What happens to the active site of an enzyme when pH changes?

  It changes shape, affecting substrate binding
• What is the optimal pH for most enzymes in the human body?

  Around 7 (neutral)
• What is the optimal pH for enzymes in the stomach?

  Around 2
• What are the effects of temperature and pH on enzymes?

  • Temperature increases reaction rate until denaturation
  • Optimal temperature is around 37°C
  • pH affects enzyme shape and activity
  • Optimal pH varies (around 7 for most, 2 for stomach)
