temp and enzyme activity

    Cards (4)

    • enzymes have optimum temps which they catalyse reactions at a max rate
    • lower temps
      • slow due to less KE
      • lower frequency of successful collisions- subtrate and as
    • denaturation
      • increased KE of enzymes puts strain on its bonds
      • weaker H+ and ionic bonds
      • causes tertiary structure of enzymes to change
      • AS damaged and no longer complementary shape to substrate so no longer binds
    • some chemical reactions in organisms take place faster at higher temps and some at lower temps
      species change distribution in response to changing temps in order to survive
