Document Summary
If the cell receives a well-formulated question, it will respond in an organized fashion. The nature of the order (what do you want), how are you going to say it, how it gets there, how its received at the other end, interpreting the message properly. Conserved mechanisms essential for; communication is important for a number of activities. The target cell has to respond to the message it receives. The target tissues for steroid hormones do not have receptors on the membrane surface for these hormones, because these hormones are soluble in the lipid bilayer. Chemical messengers 6 classes steroids lipids (not every lipid eicosinoids) peptides or proteins depends on length purines amines gases. Steroids lipid soluble, hydrophilic, lipophilic receptor located inside the cytosol or nucleus. *should be able to recognize a steroid look for 4 rings to know it"s a steroid. Peptides/protein their particularities, depending on their structure they can be active or inactive they don"t readily diffuse across membrane.
