Bio B3 Enzymes

HideShow resource information
Proteins
Long chains of amino acids.
1 of 25
Antibodies
Chemicals produced by the white blood cells to destroy pathogens.
2 of 25
Muscles
Protein fibres that contract to bring about movement
3 of 25
Tendons
Protein tissues that connect muscle to bone.
4 of 25
Enzymes
Biological catalysts that speed up reactions in the body.
5 of 25
Changing the rate of a reaction: Adding a catalyst
Chemicals that increase the rate of the reaction without being actively used up itself.
6 of 25
Changing the rate of a reaction: Increasing the concentration
There will be more particles in the same volume so there is a higher chance of collisions.
7 of 25
Changing the rate of a reaction: Increasing the temperature
There will be more kinetic energy so collisions are more likely.

Enzymes in the mouth
Salivary amylase
9 of 25
Enzymes in the stomach
Pepsin (gastric protease)
10 of 25
Enzymes in the small intestine
Pancreatic amylase, pancreatic protease, pancreatic lipase, bile
11 of 25
pH in the mouth
pH7 - neutral
12 of 25
pH in the stomach
pH2 - acidic (HCl to kill bacteria)
13 of 25
pH in the small intestine
pH9 - alkaline (to neutralise acid from the stomach)
14 of 25
Where is bile made, stored and released?
Made - liver, Stored - gall bladder, Released - small intestine via the bile duct
15 of 25
Products of protein digestion
Proteins (protease) ----> amino acids
16 of 25
Products of starch digestion
Starch (amylase) -----> glucose
17 of 25
Products of fat digestion
Fats (lipase) ----> fatty acids + glycerol
18 of 25
Where is protease made and used?
Made - stomach, small intestine, pancreas ... Used - stomach, small intestine
19 of 25
Where is amylase made and used?
Made - salivary glands, pancreas, small intestine ... Used - mouth, small intestine
20 of 25
Where is lipase made and used?
Made - pancreas, small intestine ... Used - small intestine
21 of 25
Enzymes in industry - protease
Pre-digests proteins in baby foods making it easier for babies to digest it while still giving them the amino acids they need.
22 of 25
Enzymes in industry - carbohydrase
Converts starch into sugar syrup. This is widely used by manufacturers due to its low cost.
23 of 25
Enzymes in industry - isomerase
Converts glucose into fructose which is sweeter in the same quantity. Used in slimming foods as less sugar is required.
24 of 25
Enzymes in industry - biological detergents
Contains protease and lipase that remove stains by breaking down proteins and fats. Requires low temperatures (cheaper) so enzymes aren't denatured.
