Bile,pH and Temperature, Enzyme Activity Flashcards
Pattern between temp and enzyme activity
As the temperature increases, the enzyme activity also increases
What is optimum temperature
Temperature at which the reaction is highest
Beyond the optimum
Beyond the optimum temperature, rate of reaction drops rapidly.
pH
Potential of Hydrogen
on the pH scale if is below 7
It is an acid
If the PH is 8+
It is an alkaline
How does the pH affect the way an enzyme works
The pH can affect the shape of the enzyme
As of the shape of the enzyme changing shape….
It changes the shape of the active shape
Does the pH interfere with bonds
Yes
Bile
How does it work
Step 1
It is made in the liver
Step 2
Stored in the gall bladder
Step 3
Alkaline to neutralise hydraulic acid from stomach
Step 4
Emulsifies fat to form small droplets
Emulsification
When a large drop of oil turns into small droplets as of bile
How does bile help
As of the bile turning it into small droplets it increases the surface area
What is it broken down by
Lipase
What does alkaline bile do
Neutralises the acid to give a high pH for the enzymes from the pancreas and small intestine to work well
Is bile an enzyme
No as it does not break down fat molecules. Instead it emulsifies it
