Question
What leads to a loss of insulin secretion in a type 1 diabetic?Group of answer choicesDeath of the pancreatic beta cells.Decreased activity of the immune system.Reduced sensitivity of the pancreatic beta cells.Insulin resistance in the muscle cells.
Solution
The loss of insulin secretion in a type 1 diabetic is primarily caused by the death of the pancreatic beta cells. This is the correct answer among the provided choices.
Here's a step-by-step explanation:
-
Type 1 diabetes is an autoimmune condition. This means that the body's immune system mistakenly attacks healthy cells.
-
In the case of type 1 diabetes, the immune system specifically targets and destroys the beta cells in the pancreas. Beta cells are responsible for producing insulin, a hormone that helps regulate blood sugar levels.
-
As the beta cells are destroyed, the pancreas is unable to produce sufficient insulin. This leads to an increase in blood sugar levels, which is a characteristic symptom of diabetes.
-
Therefore, the death of pancreatic beta cells leads to a loss of insulin secretion in a type 1 diabetic.
The other options - decreased activity of the immune system, reduced sensitivity of the pancreatic beta cells, and insulin resistance in the muscle cells - are not the primary causes of type 1 diabetes.
