The following points highlight the five main types of receptors found in animals. The types are: 1. Intracellular Receptors 2. Cell Surface Receptors 3. G-Protein Coupled Receptors 4. Ion-Channel Receptors 5. Tyrosine Kinase Linked Receptors. Type # 1. Intracellular Receptors: Steroid hormones, thyroxin and retinoids are lipophilic and are transported by carrier proteins in the […]
