SHAPE
1. COMPLEMENTARY
  1. ENZYME - SUBSTRATE COMPLEX
    1. PRODUCT
    2. INHIBITION
      1. COMP INHIBITORS ARENT THE MOST EFFECTIVE. LEVEL OF INHIBITION DEPENDS ON CONCENTRATION OF ENZYME AND SUBSTRATE
      2. NON COMP. MOST EFFECTIVE. BIND ELSEWHERE ON ENZYME. LEVEL OF INHIBITION DEPENDS ON THE NUMBER OF INHIBITOR MOLECULES PRESENT
  2. ONLY ONE TYPE OF REACTION IS CATALYSED
2. HYPOTHESISE
  1. LOCK AND KEY
    1. SPECIFIC SHAPE. COMPLEMENTARY. FIT. SUSTRATE IS KEY. ACTIVE SITE IS LOCK.
  2. INDUCED FIT
    1. CHANGE IN SHAPE. MORE CLOSE FIT. OPPOSITELY CHARGED GROUPS ON SUBSTRATE. STRAIN PLACED ON SUBSTRATE. DESTABILISES SUBSTRATE
THEY REDUCE THE AMOUNT OF ACTIVATION ENERGY REQUIRED
1. ACTIVATION ENERGY IS THE AMOUNT OF ENERGY THAT MUST BE APPLIED FOR A REACTION TO TAKE PLACE. DIFFRENT REACTIONS REQUIRE DIFFERENT ACTIVATION ENERGY ENERGIES. ENZYMES DECREASE ACTIVATION ENERGY
DRIVES METABOLIC REACTIONS
1. MALTOSE CAN BE BOILED IN ACID TO BREAK THE GLYCOSIDIC BONDS AND SPLIT WATER MOLECULES THEN VOND THE SPLIT PARTS OF THE WATER MOLECULES ON TO THE SPLIT PARTS OF THE MALTOSE MOLECULES TO FORM TWO GLUCOSE MOLECULES
  1. CLEARLY WE CANT SURVIVE BOILING ACIDS IN OUR CELLS...THATS WHAT ENZYMES ARE THERE FOR
ENZYMES AND TEMPERATURE
1. HEAT = MORE KINETIC ENERGY = MORE FREQUENT COLLISIONS = COLLIDE WITH GREATER FORCE = MORE COLLISIONS EXCEEDING ACT.EN.
  1. INCREASED RATE OF REACTION AND MORE PRODUCTS ARE FORMED
  2. HEAT MAKE THE MOLECULES VIBRATE= STRAIN ON THE BONDS HOLDING EM TOGETHER
    1. IONIC BOND AND HYDROGEN BONDS ARE BROKEN . THEY ARE RESPONSIBLE FOR THE TERTIARY STRUCTURE
      1. STRUCTURE UNRAVELS = ACTIVE SIGHT IS LOST= REACTION SLOWS DOWN
