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.

Given the existence of leak channels for both K and Na , could the membrane repolarize C688 if the voltage-gated K channels did not exist?
Which of the following statements best describes the features of voltage-gated K+ channels? They consist of 4 subunits, are activated at the same time as voltage-gated Na+ channels, but do not inactivate. They consist of 4 subunits, are activated by depolarisation and close slowly during the refractory period. They have 24 membrane spanning alpha helices, 4 of which have positively charged amino acids which promote a conformational change in the channel following depolarisation. They consist of 4 subunits and are open at rest which causes the resting membrane potential to be close to the K+ equilibrium potential.
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.
Clostridium tetani toxin blocks the exocytosis of GABA. A. What anatomical part of a pre-synaptic neuron would be affected by this? B.

The top panel (a) of this figure shows the graded potential change (far right, upper, electrical trace) that results from ligand binding to the ligand gated Na+ channel. The bottom panel of this figure (b) shows a graded potential change (far right, lower, electrical trace) that results from ligand binding to a ligand gated Cl- channel. From this trace you know (Vm = -70 mV) 1. ECl- is -70 mV 2. ECl- is more negative than -70 mV (i.e., -80 mV) 3. ECl- is more positive than -70 mV (i.e., -60 mV)
Why was the postsynaptic CA1 neuron voltage clamped to +30 mV? To stimulate insertion of AMPA receptors into the postsynaptic membrane To move NDA receptors into the synapse from an extrasynaptic site To cause coordination between the pre- and postsynaptic neuron To increase conductance of the NMDAR by removing the Mg?* block To stimulate AMPA receptors, which in turn activate NMDA Rs Explain the results obtained when AP5 was applied while the neuron was held at +30 mV. What is the interpretation of the result?
The membrane potential in animal cells, but not in plants, depends largely on resting K+ channels. How do these channels contribute to the resting membrane potential?

An experimental cell line expresses K+ inward rectifier channels, Na+ leak channels, K+ channels activated by the elevated levels of cytosolic Ca2+, Cl- channels activated by PKC, aquaporins, and α-1 adrenergic receptors (GPCRs that activate Gαq/11 signalling pathway). No voltage-gated channels of any kind are present. The resting membrane potential of these cells is about –50 mV, and they are bathed in the standard extracellular solution. The intracellular concentrations of the relevant ions are as follows: K+ 130 mM, Na+ 15 mM, Cl- 30 mM, Ca2+ 10-4 mM. What will happen to the cell volume if α-1 adrenergic receptor agonist is applied to the bath? Explain your answer.
