Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.

Question

27) One of the main differences between receptor tyrosine kinase (RTK) signaling and G-protein coupled receptor (GPCR) signaling is that:

GPCR signaling involves enzyme cascades, while RTK signaling does not.
		Only RTK signaling involves kinase activity.
		Only GPCR signaling involves a GTPase.
		GPCR signaling is more likely to have a short-term, reversible effect.

The G protein coupled receptor (GPCR) pathway elicits diverse intracellular responses in different cells. The basic steps of GPCR signaling are outlined in this diagram. Which of the following statements correctly describes the process of GPCR signaling? The GPCR activation is reversible after the signal of the ligand diminishes. The membrane-embedded enzyme uses GTP as a secondary messenger to initiate gene expression. The ligand attaches to both the GPCR and the membrane-embedded enzyme to activate the GPCR pathway. The ligand-bound GPCR sends a GTP molecule to an enzyme in the membrane and switches it into an active state.
Name three features common to the activation of cytokine receptors and receptor tyrosine kinases. Name one difference with respect to the enzyme activity of these receptors.
Activation of certain GPCRs triggers an intracellular signaling mechanism that involves activation of adenlyl cyclase and an increase of cAMP. Which of the following statements best describes the the events that follow such a cAMP increase? a.) The cAMP increase leads to activation of protein kinase C. b.) The cAMP increase leads to activation of the release of the gamma subunit from the GPCR. c.) The cAMP increase leads to activation of protein kinase A.

In this mechanim of receptor regulation, there is uncoupling of the signaling pathway.

Two protein kinases, barley kinase and hops kinase, function sequentially in an intracellular signaling pathway. If either kinase contains a mutation that permanently inactivates it, no response is seen in cells when an extracellular signal is received. A mutation that permanently activates barley results in a response even when there is no extracellular signal. You characterize a double mutant in which hops has the inactivating mutation and barley has the activating mutation. You observe that a response is seen in the double mutants even in the absence of an extracellular signal. In the normal signaling pathway, does barley phosphorylate hops or does hops phosphorylate barley? Briefly explain your answer.
