Cb1 f and g

• Enzymes are biological catalysts that speed up reactions in the body
• Enzymes have an active site where substrates bind to form a complex
• Factors affecting enzyme activity:

  • Temperature
  • pH
  • Substrate concentration
  • Presence of inhibitors or activators
• Denaturation occurs when enzymes lose their shape and function due to extreme temperature or pH
• Substrates are the molecules that enzymes act upon to produce a product
