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 Since it can enter the cell, it directly affects some specific cell process It might trigger a signal cascade that causes some effect in a cell It is a steroid Its receptor is located in the cytosol of the target cell Since it can enter the cell, it directly affects some specific cell process It might trigger a signal cascade that causes some effect in a cell It is a steroid ANSWER DOWNLOAD EXAMIANS APP

Cell Signalling and Transduction Which of the following statements about G proteins is false? They become activated when bound to GDP They bind to and are regulated by guanine nucleotides They are involved in signal cascades They must be active before the cell can make needed cAMP They become activated when bound to GDP They bind to and are regulated by guanine nucleotides They are involved in signal cascades They must be active before the cell can make needed cAMP ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction The signaling molecules called steroid hormones bind to cell surface receptors to trigger chemical cascades never enter the blood of humans are made in one location of the body but have their effects some distance away are hydrophilic and so cannot penetrate the plasma membrane bind to cell surface receptors to trigger chemical cascades never enter the blood of humans 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
