Summary Introduction

To explain: The difference between the intracellular receptors and cell surface receptors on the basis of binding to its signal molecule.

Introduction: The receptors are the chemical structures that bind with the signal molecules called ligand. The ligand molecules can be proteins, peptides, and lipids that induce the signal transduction pathway with binding to the receptor molecules. For instance, the ligand acetylcholine binds to the acetylcholine receptor that induces the transmission of nerve impulse between the nerves.
