Q8. What is a negative feedback loop? Give an example. What is a set point? What are effectors? Explain the glucagon-insulin feedback loop.

Background

Topic: Feedback Mechanisms in Homeostasis

This question tests your understanding of how the body regulates internal conditions using feedback loops.

Key Terms:

• Negative Feedback Loop: A process that reverses a change to maintain homeostasis.

• Set Point: The ideal value for a physiological parameter.

• Effectors: Organs or cells that act to restore homeostasis.

• Glucagon-Insulin Feedback Loop: Mechanism regulating blood glucose levels.

Step-by-Step Guidance

1. Define negative feedback and consider how it works to maintain stability.

2. Think of a common example, such as temperature regulation or blood glucose control.

3. Identify the set point (e.g., normal blood glucose level) and the effectors (e.g., pancreas, liver).

4. Outline the steps in the glucagon-insulin feedback loop: insulin lowers blood glucose, glucagon raises it.

Q9. What is a positive feedback loop? Give an example.

Background

Topic: Positive Feedback Mechanisms

This question tests your understanding of processes that amplify changes rather than reverse them.

Key Terms:

• Positive Feedback Loop: A process that increases the change from the set point.

Step-by-Step Guidance

1. Define positive feedback and consider how it differs from negative feedback.

2. Think of examples, such as blood clotting or childbirth.

3. Reflect on why positive feedback is less common and usually occurs in specific situations.
