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 is incapable of signal transduction It is in the heart muscle It is also the site of production for the signaling molecule It contains the receptor for the signaling molecule It is incapable of signal transduction It is in the heart muscle It is also the site of production for the signaling molecule It contains the receptor for the signaling molecule 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 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 makes the receptor more likely to capture the signaling, molecule changes the shape and thus the enzymatic activity of the proteins involved ANSWER DOWNLOAD EXAMIANS APP
