Exam 32: The Reception and Transmission of Extracellular Information

The members of the protein kinase C family that are regulated by Ca⁺⁺, by diacylglycerol and by phosphatidylserine are called the:

____ act as an antidepressant by ____ levels of catacholamines in the brain.

Which of the following is NOT an event that would occur upon the binding of a hormone to a receptor?

How are the receptors that mediate transmembrane signaling processes classified?​

All are domains of receptor tyrosine kinase EXCEPT:

All are inhibitors of acetylcholinesterase EXCEPT:

Hormones and other signal molecules bind with ____ affinities to their receptors and are produced at concentrations ____ their K_D values.

Steroid hormones, such as glucocorticoids, effect their action by:

The insulin receptor is in what class of tyrosine kinase receptors?

All are catecholamine neurotransmitters EXCEPT:

Neurotransmitters must be removed from the synaptic cleft to:

Lithium salts have been used for years for the treatment of manic depression. Although its mechanism of action at the molecular level is far from clear, it has been shown that Li⁺:

The amount of cAMP generated in the cytoplasm is dependent on the:

The binding of hormone to G-protein coupled receptor stimulates the sequence: A.binding of Gα (GTP) activates adenylyl cyclase B.Gα(GTP) dissociates and re-associates with Gβγ C.rapid exchange of GDP for GTP on Gα D.GTPase of Gα hydrolyzes GTP to GDP E.Gα dissociates from Gβγ

All are characteristic of EF-hand proteins EXCEPT:

All are results of the phospholipase C activity mediated by hormone binding, signal transduction and eventually Ca⁺⁺ release into the cytoplasm EXCEPT:

During an action potential, which of the following is directly responsible for restoration of resting membrane potential?

The original phorbol esters are natural products that mimic ____ by binding and activating ____ that potentiate the effects of ____.
