Cell Signalling and Transduction A cell is known to respond to a particular signaling molecule. Which of the following must be true of this cell? It contains the receptor for the signaling molecule It is also the site of production for the signaling molecule It is in the heart muscle It is incapable of signal transduction It contains the receptor for the signaling molecule It is also the site of production for the signaling molecule It is in the heart muscle It is incapable of signal transduction 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 allows hydrophilic signaling molecules to cross the plasma membrane makes the receptor more likely to capture the signaling, molecule None of these changes the shape and thus the enzymatic activity of the proteins involved allows hydrophilic signaling molecules to cross the plasma membrane makes the receptor more likely to capture the signaling, molecule None of these ANSWER DOWNLOAD EXAMIANS APP
