Summary Introduction

Introduction:

Signal transduction pathway involves three steps that are reception, transduction, and response. Reception includes binding of the signal molecule on the receptors present on plasma membrane; transduction involves activation of several molecules present in the cell, which finally leads to activation of the target molecule. Response appears when the target protein brings about the required change. Transduction step involves a cascade of reactions in which the activation of one molecule catalyzes the activation of other molecule.
