Enzymes & Digestion

• enzymes are affected by temperature if the temperature is too high it will denature. 37 degrees is the peak temperature
• Changes in the environment can cause a protein to denature. Denaturation means a protein loses its shape
• denaturing means that it can no longer bind to its substrate as effectively as the active site would change shape
• The optimal temperature allows more frequent and succesful collisions since they have a higher kinetic energy.
• enzymes are affected by ph levels with the average level being 7.35 but other specific enzymes can tolerate higher and lower levels
• the ph level in the stomach would have a higher ph due to the acidic nature.
• The higher the concentration of enzymes, the more likely it is that a substrate will collide with an enzyme
• Lock and Key

  Each enzymes have a complemantry shape that allows it to fuse and become an enzyme-substrate. The active site is were the reaction takes place
• enzyme=lock

  substrate=key
• rate= change in amount of reactants/ time
• Increase temp too much causes denaturation which means the enzyme loses its structure and becomes useless
• Enzymes are biological catalysts
• Enzymes reduce the activation energy (Ea) of a chemical reaction
