Final answer:
The idea that most type 2 diabetics do not produce insulin is false; they produce insulin but the body's cells are resistant to it. This condition leads to high blood glucose levels and cellular starvation despite the presence of insulin.
Step-by-step explanation:
The statement that most type 2 diabetics do not produce insulin is false. In type 2 diabetes, the pancreas typically continues to produce insulin, but the body's cells become resistant to its effects, which is often referred to as insulin resistance. This means that while there is an adequate amount or sometimes even an excess of insulin in the bloodstream, the cells cannot use it effectively to take up glucose. This situation can be described as the patients being "starving in a sea of plenty," because glucose remains in the bloodstream instead of being used as energy by the cells, leading to hyperglycemia (high blood glucose levels) and cellular starvation.
In type 2 diabetes, a negative feedback loop cannot proceed correctly because even though there is enough insulin, the cells cannot respond to it properly. The body's mechanism for lowering blood sugar is compromised, contributing to the problem of glucose homeostasis.
