Question

Does a homeostatic feedback loop only function when there is a change from the set point?

a) Yes, the loop initiates only when the set point is altered.
b) No, continuous adjustment occurs around the set point.
c) Yes, changes trigger the feedback loop response.
d) No, the loop is inactive when the set point is reached.

Answer 1

The correct answer is b) No, continuous adjustment occurs around the set point, as homeostatic feedback loops work to maintain equilibrium within a narrow range through a continuous process.

Step-by-step explanation:

A homeostatic feedback loop functions to maintain the physiological state within a narrow range that is compatible with life, returning the body to homeostasis. Therefore, the correct answer to the question is b) No, continuous adjustment occurs around the set point. This means that while there are fluctuations, the loop is always working to maintain the normal range. A negative feedback loop is one of the primary mechanisms of homeostasis, serving to reduce the excessive response and keep a variable close to the set point. Alternatively, a positive feedback loop pushes an organism's physiology further away from its normal setpoints.
