    Which of the following statements is true?

    A) When signal molecules first bind to receptor tyrosine kinases, the receptors phosphorylate a number of nearby molecules. 

    B) In response to some G-protein-mediated signals, a special type of lipid molecule associated with the plasma membrane is cleaved to form IP3 and calcium. 

    C) In most cases, signal molecules interact with the cell at the plasma membrane and then enter the cell and eventually the nucleus. 

    D) Toxins such as those that cause botulism and cholera interfere with the ability of activated G proteins to hydrolyze GTP to GDP, resulting in phosphodiesterase activity in the absence of an appropriate signal molecule. 

    E) Protein kinase A activation is one possible result of signal molecules binding to G protein- linked receptors.

    As humans, we have receptors for two kinds of beta adrenergic compounds such as 

    catecholamines. Cardiac muscle cells have beta 1 receptors that promoteincreased heart rate. Some drugs that slow heart rate are called beta blockers. Smooth muscle cells, however, have beta 2 receptors which mediate muscle relaxation. Blockers of these effects are sometimes used to treat asthma.

    The description above illustrates which of the following? 

    A) Just because a drug acts on one type of receptor does not mean that it will act on another type. 

    B) Beta blockers can be used effectively on any type of muscle. 

    C) Beta adrenergic receptors must be in the cytosol ifthey are going to influence contraction and relaxation. 

    D) The chemical structures of the beta 1 and beta 2 receptors must have the same active sites. 



    A) Just because a drug acts on one type of receptor does not mean that it will act on another type.
