|
Name two shapes of proteins |
Conjugated, Globular or fiborus |
|
|
List the five main functions of proteins |
receptors, enzymes, antibodies, structural and hormones. |
|
|
What is an enzyme? |
A biological catalyst and can be found in all living cells |
|
|
Are enzymes living or non- living? |
Non-living |
|
|
What are the features of an enzyme? |
They are specific to a certain substrate and they have an active site that complements the substrate. |
|
|
What happens to an enzyme after being used? |
It remains unchanged and can be used again |
|
|
Name two type of enzyme reactions. |
Degradation and synthesis. |
|
|
What is a degradation reaction? |
When an enzyme breaks down a substrate into its product. |
|
|
What is a synthesis reaction? |
When an enzyme builds up a substrate into its product. |
|
|

|
|
What does HPCOW stand for? |
....................................Catalase................................. Hydrogen Peroxide-----------------> oxygen + water |
|
|
What does PPP stand for? |
..............................Pepsin.......................................... Protein ------------------------------------> Peptides |
|
|
What does FLiFAG stand for? |
......................Lipase.................................................. Fats ------------------------------> Fatty acids + Glycerol |

|
What does G1PPS stand for? |
........................................phosphorylase.................. Glucose -1-phosphate -------------------------> Starch |
|
|
Which enzyme reaction is an example of a synthesis reaction? |
.......................................phosphorylase..................Glucose -1- phosphate -------------------------> Starch |
|
|
What does optimum mean? |
When enzymes work their best
|
|
|
How can enzymes be affected? |
By temperature and pH |
|
|
What will happen if the temperature of the enzyme is too cold? |
it would work slowly |
|
|
What would happen if the temperature of the enzyme was too hot? |
It would denature the enzyme |
|
|
What does denature mean? |
The shape of the enzyme is altered, therefore it is unable to bind with its substrate. |
