Cell Signalling and Transduction The signaling molecules called steroid hormones never enter the blood of humans bind to cell surface receptors to trigger chemical cascades are made in one location of the body but have their effects some distance away are hydrophilic and so cannot penetrate the plasma membrane never enter the blood of humans bind to cell surface receptors to trigger chemical cascades are made in one location of the body but have their effects some distance away are hydrophilic and so cannot penetrate the plasma membrane ANSWER DOWNLOAD EXAMIANS APP
