Enzymes and Digestion
- Digestive enzymes breakdown big molecules into smaller ones
- 1. Starch, protein and
fats are BIG molecules
- 2. Sugars, amino acids, glycerol
and fatty acids are much smaller
molecules
- They can pass through the
walls of the digestive system
easily
- They can pass through the
walls of the digestive system
easily
- 1. Starch, protein and
fats are BIG molecules
- Diagram of convertion of
enzymes
- Bile neutralise the stomach acid:
- Bile is produced
in the liver
- Bile stored in the Gall
Bladder before released
into the Small intestine
- Bile is alkaline
- It neutralise the acid and
makes conditions alkaline
- It neutralise the acid and
makes conditions alkaline
- Enzymes work best in
alkaline condition in Small
intestine
- Bile is produced
in the liver
- Emulsifies
- It emulsifies fats
- Breaks the fat into tiny droplets
- Gives a bigger surface area of
fats for enzymes lipase to work
on.
- Which make it digestion faster
- Which make it digestion faster
- Gives a bigger surface area of
fats for enzymes lipase to work
on.
- Breaks the fat into tiny droplets
- It emulsifies fats
- More on enzymes and digestion
- The breakdown of
food is catalysed by
enzymes
- 1. Enzymes used in the digestive system
- Produced by specialised cell in
the glands and gut lining
- Produced by specialised cell in
the glands and gut lining
- 2. Different enzymes catalyse the
breakdown of different food
molecules
- The breakdown of
food is catalysed by
enzymes
