Multiple Choice
Generally, what is the result of the negative feedback process in biological systems?
A
Stabilization of a physiological variable near a set point
B
Amplification of the original stimulus
C
Initiation of a new metabolic pathway
D
Disruption of homeostasis
Verified step by step guidance1
Understand the concept of negative feedback: Negative feedback is a regulatory mechanism in biological systems where a change in a physiological variable triggers a response that counteracts the initial change, helping to maintain homeostasis.
Identify the role of negative feedback in maintaining homeostasis: Negative feedback works to stabilize physiological variables, such as body temperature, blood glucose levels, or blood pressure, near a set point.
Eliminate incorrect options: Amplification of the original stimulus is characteristic of positive feedback, not negative feedback. Initiation of a new metabolic pathway and disruption of homeostasis are not outcomes of negative feedback.
Focus on the correct option: The stabilization of a physiological variable near a set point aligns with the purpose of negative feedback, as it helps maintain balance in the system.
Conclude that the correct answer is 'Stabilization of a physiological variable near a set point,' as this is the primary result of the negative feedback process in biological systems.
