Transcript of Carbohydrate (starch)
Second stop: The Liver!
We are potatoes entering the body through the mouth
and will be going on several stops. Potatoes are a good
source of carbohydrates (starch)! Carbohydates are organic
molecules in which hydrogen, oxygen and carbon join
together in the ratio of Cx(H2O)y. Carbohydrates are sugars that provide the body with energy. The body breaks down carbohydrates quickly and efficiently.
We enter the body as potatoes and start
off in the mouth! The mouth chemically digests Carbohydrates.
Chemical digestion is a process that breaks down large food parts into small moleclues
Carbohyradtes are the main source
of energy for the human body. As we are munched
and crunched by the stong teeth, the saliva helps
the broken down potato sild down the throat.
The first stop is the bloodstream! when humans eat starch
an enzyme occurs. In the saliva and intestines, it breaks
the bonds between the repeating glucose units,That is called
amylase. That allows the sugar to be absorbed into the
bloodstream. The body then distributes glucose to the areas
where energy is needed. The body depends on the bloodstream to deliver a constant supply of this fuel.
The second stop is the liver!
When Carbohydrates enter the body they are broken down into energy. If the body does not need the energy it is stored in the liver. Once the body distributes glucoes to the areas that need it, the excess glucose bonds together and form glycogen molecules. Animals store it in the muscle tissue or the liver and is used for a "instant" energy source.
The Nervous System!
Nerve cells function upon glucose.when insufficient carbs get eaten it can
take up to a fast three weeks or more for the cells of the central nervous
system to adapt their metabolic apparatus to use ketone bodies to take
place of glucose. (Ketone bodies are substances synthesized by the liver as a stop in the metabolism of fats.)
The nerve cells gain their needed amount of functional energy from the metabolites
The third stop:
Carbohydrates are a main source of energy, they provide fuel for our muscular system. Our body works more efficiently with Carbohydrate intake. People who engage more in physical acitivity have larger stores os glycogen in their muscles. This is why it is important to increase our exercise to help our storage of muscle glycogen.
certain foods in the body can not digest like sugar, starches, and fibers in charbohydrates, because of a shortage of digestive enzymes. So the undigested foods pass into the colon. In the colon that is where the body produces hydrogen, carbon dioxide, and in some people, methane. In time the gases have to exit the body and that would result in a fart/ pass of gas.
What else do carbohydrates do for the body?
-Protects our muscles
-Provides nutrients for bacteria in the intesinal tract to digest food
-Helps the body absorb calcium
- Can help lower cholesteral
