Chapter 14: Signal Transduction Mechanisms: Messengers and Receptors Signal Transduction Mechanisms: II. Messengers and Receptors In the second major means of intercellular communication the signal is transmitted by regulatory chemical messengers Receptors are located on receiving cells that can be quite distant from the secreting cell Chemical Signals and Cellular Receptors Cells produce signals‚ in some cases by displaying molecules on their surfaces or by releasing a chemical signal Multicellular

distances. Around that same time‚ Nikola Tesla was diligently trying to master the alternate current (AC) motors and generators even though he was discouraged from doing so. After proving his invention to be a practical solution for this problem‚ George Westinghouse purchased Tesla’s patents and opened his first power plant that supplied AC electricity to parts of Massachusetts and New York. With AC being able to distribute over long distances‚ this was the obvious choice and is now used all over the

In other words‚ it is a power adopter. It allows a battery – based system to run conversional AC appliances director through conventional home wiring. There are ways to use DC directly‚ but for a modern lifestyle you will need an inverter for the vast majority if not all your loads in
