Presentation Transcript

  1. ENZYME

  2. Enzymes are proteins that are used by the cell to speed up and regulate metabolic reactions. Enzymes are biological catalysts that remain unchanged by the reaction. Enzymes

  3. The substrate is temporarily bound to its enzyme at the active site. The enzyme may change shape slightly to accommodate the substrate. Enzymes

  4. ENZYMES ARE VERY PICKY!!!! ENZYMES ARE VERY PICKY. TEMPERATURE IF IT GETS TOO HOT, TOO COLD – THEY CHANGE SHAPE pH IF IT BECOMES TOO ACIDIC – THEY CHANGE SHAPE IF

  5.  a sad enzyme 

  6. How could we speed up this reaction? • Was the bench (enzyme) changed by the reaction? • Would this bench work on ants or elephants? • What if we burned the bench? It would not work – the shape has been changed. • Would 12 M H2SO4 (sulfuric acid) destroy the bench? Would lye (a base) destroy the bench? Yes, these substances could burn holes in the bench. So acids and bases can definitely affect enzyme function.

  7. LUCIFERASE enzyme creates light

  8. LACTASE

  9. AMYLASE breaks down starches
