Enzymes

  • Globular proteins
  • biological catalysts whcih speed up reactions
  • have an active site, where substrates attach
  • form a enzyme-substrate complex

What is the active site?
region on the enzyme the substrate binds to
1 of 6
What do enzymes do?
reduce activation energy
2 of 6
What is effect of temperature of enzyme activity?
increases it to a point(optimum temp) where it then denatures
3 of 6
What is the effect of pH on enzyme activity?
enzyme works best in its optimum pH range
4 of 6
What is the effect of competitive inhibitors on enzymes?
binds to the active site temporarily and lowers reaction rate
5 of 6
What is the effect of non-competitive inhibitors on enzymes?
binds to the enzyme permanently, irreversible
