What Is Insulin-dependent Diabetes?
When you eat,your body takes the sugar from food and turns it into fuel.______(46)Your body uses glucose for energy,so it can do everything from breathing air to playing a video game.But glucose can't be used by the body on its own-it needs a hormone called insulin to bring it into the cells of the body.
Most people get the insulin they need from the pancreas,a large organ near the stomach?The pancreas makes insulin;insulin brings glucose into the cells;and the body gets the energy it needs.When a person has insulin一dependent diabetes,it's because the pancreas is not making insulin.So someone could be eating lots of food and getting all the glucose he needs,but without insulin,there is no way for the body to use the glucose for energy.______(47)

When a kid is diagnosed with juvenile(insulin-dependent)diabetes,he will have that type of diabetes for his whole life.It won't ever change to non-insulin-dependent diabetes when he gets older.
Scientists now think that a person who has juvenile diabetes was born with a certain gene or genes that made the person more likely to get the illness.______(49)
Many scientists believe that along with having certain genes,something else outside the person's body, like a viral infection,is necessary to set the diabetes in motion by affecting the cells in the pancreas that make insulin.
But the person must have the gene(or genes)for diabetes to start' out with一this means you can't get diabetes just from catching a flu,virus,or cold.And this type of diabetes isn't caused by eating too many sugary foods,either.Diabetes can take a long time to develop in a person's body-sometimes months or years?Another important thing to remember is that diabetes is not contagious.______(50)
______(46)
A.Genes are something that you inherit from your parents,and they are in your body even before you're born.
B.This sugar-fuel is called glucose?
C.It may be possible to beat insulin resistance through lifestyle changes.
D.You can't catch diabetes from people who have it,no matter how close you sit to them or if you kiss them.
E.The glucose can't get into the cells of the body without insulin.
F.When a person has this kind of diabetes,the pancreas usually can still make insulin,but the person's body needs more than the pancreas can make?
