Question
Chapter 32.1, Problem 4CYL
Summary Introduction
To explain:
Definition of positive feedback and explain why it rare in living organism.
Introduction:
Humans and other mammals are the most advanced form of life on the planet earth. They have several advanced mechanisms in their body, mechanisms that prevent alteration in the working conditions of the body even at the cellular level. The main focus of these mechanisms is on preventing the denaturation of enzymes which catalyze all the biological reactions in the body.
