Cell Signalling and Transduction Which of the following is true about a hydrophilic signaling molecule? Since it can enter the cell, it directly affects some specific cell process Its receptor is located in the cytosol of the target cell It is a steroid 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 Its receptor is located in the cytosol of the target cell It is a steroid It might trigger a signal cascade that causes some effect in a cell ANSWER DOWNLOAD EXAMIANS APP

Cell Signalling and Transduction The signaling molecules called steroid hormones bind to cell surface receptors to trigger chemical cascades are hydrophilic and so cannot penetrate the plasma membrane never enter the blood of humans are made in one location of the body but have their effects some distance away bind to cell surface receptors to trigger chemical cascades are hydrophilic and so cannot penetrate the plasma membrane never enter the blood of humans are made in one location of the body but have their effects some distance away ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction In the signal transduction mechanism known as protein phosphorylation receptor kinases play a key role in triggering the signal cascade the signaling molecule binds to a surface receptor All of these phosphorylated proteins act with enzymes to trigger the signal cascade receptor kinases play a key role in triggering the signal cascade the signaling molecule binds to a surface receptor All of these phosphorylated proteins act with enzymes to trigger the signal cascade ANSWER DOWNLOAD EXAMIANS APP
Cell Signalling and Transduction Self-phosphorylation is an excellent mechanism for triggering specific catalytic function of the proteins involved in signal cascades because it changes the shape and thus the enzymatic activity of the proteins involved None of these allows hydrophilic signaling molecules to cross the plasma membrane makes the receptor more likely to capture the signaling, molecule changes the shape and thus the enzymatic activity of the proteins involved None of these allows hydrophilic signaling molecules to cross the plasma membrane makes the receptor more likely to capture the signaling, molecule ANSWER DOWNLOAD EXAMIANS APP
