Final answer:
Type 1 diabetes is an autoimmune disease that affects the feedback loop involved in glucose homeostasis. The beta cells of the pancreas are attacked by the immune system, leading to a lack of insulin production. Treatment for type 1 diabetes involves insulin replacement through injections or infusion.
Step-by-step explanation:
Type 1 diabetes is an autoimmune disease in which the immune system attacks the insulin-secreting beta cells of the pancreas. This affects the feedback loop involving glucose homeostasis, as the beta cells are responsible for producing insulin, which helps to regulate blood glucose levels. Without insulin, glucose cannot enter cells to be used as energy, leading to high blood glucose levels. Type 1 diabetes is treated with insulin injections or infusion to replace the missing insulin.
