What are proteins made of?
Long chains of amino acids
1 of 26
What would happen if the shape of an enzyme was to change?
It would become denatured
2 of 26
Complete this sentence: Proteins are polymers, They are built up...
In cells when monomers called amino acids join together
3 of 26
What can proteins act as?
Structural components of tissues such as muscles, Hormones, Antibodies and Catalysts
4 of 26
What are catalysts?
They increase the rate of chemical reactions.
5 of 26
What are enzymes?
Biological catalysts and are made of proteins
6 of 26
How do enzymes work?
On the enzyme there is an active site where the substrate molecule will fit to form the reaction
7 of 26
Complete this sentence: The substrate has a....
Complementary shape that fits the active site
8 of 26
How do enzymes become denatured?
Temperature and PH
9 of 26
What temperature do enzymes like to work?
Enzymes are more likely to find a substrate at 37 degrees
10 of 26
Why are peoples bodys temperature 37 degrees?
It is an enzymes optimum temperature
11 of 26
How does PH affect enzymes?
All enzymes work in different ph's
12 of 26
How do enzymes break down starch
With amalayse into glucose
13 of 26
How do enzymes breaj down protiens
With protease into amino acids
14 of 26
How do enzymes break down lipids
With lipase into fatty acids and glycerol
15 of 26
Where is amalyase produced?
In the salivary glands, pancreas and small intestine so it catalyses the breakdown in the mouth and small intestine
16 of 26
Where is protease produced and where does it work?
In the stomach, pancreas and small intestine so it catalyses the breakdown in the stomach and small intestine
17 of 26
Where is lipase produced and where does it work?
In the pancreas and small intestine so it catalyses the breakdown in the small intestine
18 of 26
What other substances are involved in digestion?
Stomach acids and bile
19 of 26
What is stomach acid?
Hydrochloric acid
20 of 26
Why does stomach acid help with digestion?
Because it makes the stomach acidic which is the best conditions for the enxymes in the stomach to work in
21 of 26
What does bile do?
Makes the food from the stomach which is acidic more alkali which is the conditions enxymes work best in the small intestine
22 of 26
Where is bile produced and stored?
It is produced in the liver and stored in the gall bladder
23 of 26
How does industry use enzymes?
Baby food, biologic detergents, sugar syrup and fructose syrup
24 of 26
What are the advantages of using enzymes in industry?
They work at low temperatures, work at low pressues, efficent and are often cheaper to run
25 of 26
What are the disadvantages of using enzymes in industry?
Can be denatured by high temperatures, sensitive to change in ph
