Digestive Enzymes Flashcards
What are large food molecules digested by
They r digested by enzymes into smaller molecules
Where r products of digestion absorbed into
The bloodstream
What does catalyse do
Speeds up chemical reactions
What r enzymes
Large protein molecules and hv a groove on their surface called the active site
What happens at the active site
It’s where substrate attaches to.
Where does the substrate fit
Fits perfectly into the active site
What does the enzyme break the substrate into
Into products
What happens if the substrate doesn’t fit into the active site
The enzyme cannot break down the substrate
What’s the lock and key theory
Where the substrate must fit perfectly into the active site
What r proteins broken down by
By enzymes called protease
What r proteins
Long chains of chemicals called amino acids
What happens when we digest proteins
The protease enzymes convert the protein bck to the individual amino acids which r absorbed into the bloodstream
What happens when amino acids r absorbed by blood cells
They r joined together in diff order to make human proteins
What does starch consist of
A chain of glucose molecules
What r carbohydrates which r broken down by enzymes called
Carbohydrases (in starch it’s called amylase)
What’s produced when starch is digested
Simple sugars
Where is amylase found
In saliva and pancreatic fluid
What do lipid molecules consist of
Glycerol which is attached to 3 molecules of fatty acids
Which enzyme r lipid molecules digested by
Lipase
What does lipase produce
Glycerol
FATTY acids
Where r lipase found
In pancreatic fluid
Nd small intestine
Wheres bile made in
The liver
Wheres bile stored
In gall bladder
What does bile do
Speeds up the digestion of Lipids
