Questions: 101 of 113 Concepts completed Multiple Choice Question How does type 1 diabetes mellitus differ from type 2 diabetes mellitus? Type 1 diabetes mellitus results from a lack of insulin, and type 2 diabetes mellitus results from an inability to respond to insulin. Type 1 diabetes mellitus results from too much insulin, and type 2 diabetes mellitus results from an inability to respond to insulin. Type 1 diabetes mellitus results from an inability to respond to insulin, and type 2 diabetes mellitus results from too much insulin. Type 1 diabetes mellitus results from an inability to respond to insulin, and type 2 diabetes mellitus results from a lack of insulin.

The answer is the first one: Type 1 diabetes mellitus results from a lack of insulin, and type 2 diabetes mellitus results from an inability to respond to insulin.

Explanation for each option:

1. Type 1 diabetes mellitus results from a lack of insulin, and type 2 diabetes mellitus results from an inability to respond to insulin.

   • This is correct. Type 1 diabetes is characterized by the body's inability to produce insulin due to autoimmune destruction of the insulin-producing beta cells in the pancreas. Type 2 diabetes, on the other hand, is primarily due to insulin resistance, where the body's cells do not respond effectively to insulin, often accompanied by a relative insulin deficiency.

2. Type 1 diabetes mellitus results from too much insulin, and type 2 diabetes mellitus results from an inability to respond to insulin.

   • This is incorrect. Type 1 diabetes is not caused by too much insulin; it is caused by a lack of insulin production.

3. Type 1 diabetes mellitus results from an inability to respond to insulin, and type 2 diabetes mellitus results from too much insulin.

   • This is incorrect. Type 1 diabetes is not due to an inability to respond to insulin; it is due to a lack of insulin production. Type 2 diabetes is not caused by too much insulin; it is characterized by insulin resistance.

4. Type 1 diabetes mellitus results from an inability to respond to insulin, and type 2 diabetes mellitus results from a lack of insulin.

   • This is incorrect. Type 1 diabetes is not due to an inability to respond to insulin; it is due to a lack of insulin production. While type 2 diabetes can eventually lead to a lack of insulin as the disease progresses, it primarily starts with insulin resistance.

In summary, the key difference is that type 1 diabetes is due to a lack of insulin production, while type 2 diabetes is due to insulin resistance.
