Is blood sugar regulated by negative or positive feedback?
Understand the Problem
The question is asking whether the regulation of blood sugar levels in the body is controlled by negative feedback mechanisms or positive feedback mechanisms. This involves understanding how the body maintains homeostasis in response to changes in blood sugar levels.
Answer
negative feedback
The final answer is negative feedback
Answer for screen readers
The final answer is negative feedback
More Information
The regulation of blood sugar levels by insulin via negative feedback is crucial for maintaining homeostasis. Pancreatic beta cells play a significant role in monitoring and responding to blood glucose levels by releasing insulin when levels are high and reducing insulin when levels are low.
Tips
A common mistake is confusing negative feedback with positive feedback. Negative feedback helps stabilize a system, while positive feedback amplifies changes.
