  1. Enzymes substrate • Enzymes are special proteins that are involved in chemical reactions. • Catalysts are used to speed up chemical reactions (some enzymes are catalysts) • Catalysts do not get used up! Active site Enzyme-substrate complex enzyme product enzyme

  2. Optimal temperature for typical human enzyme Optimal temperature for enzymes of heat tolerant bacteria Rate of Reaction Rate of Reaction 0 20 35 50 65 80 95 110 Temperature and pH • Enzymes work best at a certain temperature and pH. • High temperatures and extreme pH can alter an enzymes function. Temperature Optimal pH for pepsin Optimal pH for trypsin pH
