Definition
| A catalyst is a substance which increases the speed of a reaction without being changed or used up in the reaction. |
|
|
Term
| Describe how enzymes have special shapes to Catalyse Reactions. |
|
Definition
| Every enzyme has a unique shape that fits onto the substance involved in the reaction. For the enzyme to work the substance has to fit its substrate or else the reaction won't be catalysed. |

| What is the Optimum Temperature for Enzymes to work in the human body? |
|
Definition
|
|
Term
| What happens if a reaction gets too hot? |
|
Definition
| The bonds holding the enzyme together break. This destroyes the enzyme's special shape and so the enzyme won't work anymore - it is denatured. |

|
Definition
| 7 (but pepsin works best at 2). |

|
Definition
1. The Salivary Glands
2. The Pancreas
3. The Small Intestine |

Definition
1. The Stomach (Pepsin)
2. The Pancreas
3. The Small Intestine |

Term
What reaction does Protease catalyse? |
|
Definition
| Proteins into Amino Acids. |

Term
What reaction does Lipase catalyse? |
|
Definition
| Lipids into Glycerol and Fatty Acids. |
|
|
Term
| What is the purpose of Bile? |
|
Definition
It neutralises the hydrochloric acid in the stomach making the conditions alkaline for the enzymes to work best.
It also emulsifies fats breaking them into tiny droplets. This gives a bigger surface area for the enzyme Lipase to work on. |
