Cell Signalling and Transduction The signaling molecules called steroid hormones are made in one location of the body but have their effects some distance away never enter the blood of humans bind to cell surface receptors to trigger chemical cascades are hydrophilic and so cannot penetrate the plasma membrane are made in one location of the body but have their effects some distance away never enter the blood of humans bind to cell surface receptors to trigger chemical cascades are hydrophilic and so cannot penetrate the plasma membrane ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction Which of the following is true about a hydrophilic signaling molecule? Its receptor is located in the cytosol of the target cell It might trigger a signal cascade that causes some effect in a cell Since it can enter the cell, it directly affects some specific cell process It is a steroid Its receptor is located in the cytosol of the target cell It might trigger a signal cascade that causes some effect in a cell Since it can enter the cell, it directly affects some specific cell process It is a steroid ANSWER DOWNLOAD EXAMIANS APP
