Welcome to MooMooMath and Science
In this video, I will look at the movement
of food through the digestive system and the
enzymes along the way.
Enzymes are essential for digestion because
they help speeds up the chemical reaction.
One way an enzyme speeds up a chemical reaction
is by reducing the amount of energy needed
to start the reaction.
As the food moves along the digestive system
enzymes are added along the way.
In the mouth or oral cavity salivary glands
help start digestion.
Lipase is secreted that helps break down lipids
and amylase is secreted and this helps break
down carbohydrates.
From the mouth, the food travels down the
esophagus and into the stomach.
In the stomach, several enzymes are secreted.
Pepsin is the main enzyme in the stomach.
Pepsin breaks down the protein in the food
into smaller particles.
Protein digestion, therefore, first starts
in the stomach, and carbohydrate and lipids,
which start their digestion in the mouth.
As food exits the stomach it enters the first
portion of the small intestine called the
duodenum.
The pancreatic duct is located here and releases
enzymes produced by the pancreas.
This pancreatic juice is a combination of
at least 7 different enzymes
This pancreatic juice breaks down proteins,
glycogen, and starch
Finally, as food travels into the small intestine
additional enzymes are added.
Enzymes whose function is to further break
down the chyme released from the stomach.
You will find the following enzymes in the
small intestine.
Lactase is a significant enzyme that breaks
down lactose that is found in many dairy products.
If you are lactose intolerant you either lack
this enzyme or have a reduced amount.
So there we go.
The flow of food and the enzymes that help
you break down your food.
