I have a question that I am stuck on, any help great. Which of the following statements is true? A. When signal molecules first bind to receptor tyrosinekinases, the receptors phosphorylate a number of nearbymolecules. B. In response to some G-protein-mediated signals, a specialtype of lipid molecule associated with the plasma membrane iscleaved to form IP3 and calcium. C. In most cases, signal molecules interact with cell at theplasma membrane and then enter the cell and eventually thenucleus. D. Toxins such as those that cause botulism and cholerainterfere with the ability of activated G proteins to hydrolyze GTPto GDP, resulting in phosphodiesterase activity in the absence ofan appropriate signal molecule. E. Protein kinase A activation is one possible result ofsignal molecules binding to G protein-linked receptors. I have a question that I am stuck on, any help great.
