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 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 are made in one location of the body but have their effects some distance away ANSWER DOWNLOAD EXAMIANS APP

Cell Signalling and Transduction In paracrine signaling, the signaling molecules affects only target cells close to the cell from which it was secreted target cells distant from its site of synthesis in cells of an endocrine organ both (a) and (b) None of these target cells close to the cell from which it was secreted target cells distant from its site of synthesis in cells of an endocrine organ both (a) and (b) None of these 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 makes the receptor more likely to capture the signaling, molecule changes the shape and thus the enzymatic activity of the proteins involved allows hydrophilic signaling molecules to cross the plasma membrane None of these makes the receptor more likely to capture the signaling, molecule changes the shape and thus the enzymatic activity of the proteins involved allows hydrophilic signaling molecules to cross the plasma membrane None of these ANSWER DOWNLOAD EXAMIANS APP
