What are digestive juices?
juices that are produced in many parts of the digestive system that contains enzymes.
An example of digestive juices found in digestive parts?
Found in the small intestine that contain enzymes that break large-insoluble-starch molecules into small-soluble-glucose molecule.
the molecules has to be same size or smaller than glucose for it to be absorbed by the small intestine.
Enzymes work best at which temperature?
37 c
What is the purpose of a model in science?
To help us understand how complicated things happen.
What does the Visking tubing represent in the model?
The inside of the small intestine.
What does the water around the tubing represent?
The blood in the body.
What can pass through the Visking tubing?
Only small, soluble molecules.
Why can only small molecules pass through the tubing?
Because the tubing has microscopic holes that block large molecules.
What process does this model help demonstrate?
The absorption of digested food from the small intestine into the blood.
at what temperature does the model intestine work best?
Why?
37 degrees
because enzymes have a temperature that they work best at
all enzymes Ph is the same.
True or false
False
Where is enzymes found in the mouth
saliva
Name 3 places where enzymes can be found
mouth
stomach
small intestine
what does enzymes help break down in the mouth
starch
Enzymes work properly at what ph in the mouth?
Ph 7
what is the ph of the mouth
7
What happens to the enzymes when the food reaches the stomach
they stop working because of hydrochloric acid in the stomach
How does stomach digest proteins
it contain digestive juices that contains enzymes
Enzymes in the small intestine help break down what?
Protein
starch
fat
What is amylase?
an enzyme found in the small intestine that breaks down starch
enzymes are also found in supplements that are good for health.
True or false
true
Enzymes work is complicated.
What do we do to think about them?
Use models
What does a model represent?
the known fact about something
