Question
Chapter 1.5, Problem 4QC
Summary Introduction
To review:
The differences between positive and negative feedback loops.
Introduction:
Feedback loops play an important role in maintaining homeostasis. They are activated in response to changes in the regulated variable, and affect the same variable to bring it to its normal value. There are two types of loops, which are negative feedback loops and positive feedback loops.
