Diabetes results when either insulin cannot be produced or does not function properly. Consequently, diabetes can produce complications such as blindness, heart disease, and kidney disease. To help manage diabetes, a patient can get insulin injections. How do insulin injections promote a negative feedback loop to help maintain blood glucose production? a. Insulin injections allow transport and storage of glucose to increase blood glucose levels after consuming a large or high-glucose meal. b. Insulin injections allow only storage of glucose to decrease blood glucose levels after consuming a large or high-glucose meal. c. Insulin injections allow transport and storage of glucose to increase blood glucose levels before consuming a meal. d. Insulin injections allow transport and storage of glucose to decrease blood glucose levels after consuming a large or high-glucose meal.

Key Concepts

Diabetes Mellitus

Diabetes is a metabolic disorder characterized by either inadequate insulin production or improper insulin function. This impairment leads to chronic imbalances in blood glucose levels, potentially causing complications such as vision loss, cardiovascular disease, and kidney damage.

Negative Feedback Mechanism

This is a control process where a system responds to a change by initiating responses that counteract or reverse that change, thereby maintaining homeostasis in a biological system. In glucose regulation, a rise in blood glucose levels triggers responses that lower glucose back toward a set level.

Insulin Function

Insulin is a hormone that plays a crucial role in reducing blood glucose levels by promoting the uptake of glucose into cells and facilitating its conversion to glycogen for storage. Its action is central to the regulation of blood sugar in the body.

Blood Glucose Homeostasis

This concept pertains to the maintenance of steady levels of glucose in the bloodstream despite fluctuations due to factors like meals or fasting. The coordination of hormonal signals, including insulin and glucagon, ensures that glucose remains within a narrow range, which is essential for energy balance and overall metabolic health.

Exogenous Insulin Administration

This refers to the practice of supplying insulin from an external source, typically via injection, to manage diabetes. It helps to mimic the natural regulatory role of insulin, promoting the uptake and storage of glucose to maintain blood glucose levels within a healthy range through negative feedback.
