Describe shunting inhibition. What is the cellular mechanism, and how does it cause inhibitory effects?

Ca2+ Using Figure 8.1, answer the following questions: 6) What is occurring in Step 2 of the figure above, and how is that process originated? 6) 7) Identify the structures on the postsynaptic membrane that bind with the neurotransmitter 7) in Steps 4 and 6 of the figure above, and indicate their function. 8) In the figure above, the overall function of Steps 6-8, which occur simultaneously, is to 8) 9) Based on the figure, describe the two possible mechanisms whereby Step 5 can occur on the postsynaptic membrane. 9) 10) Based on the figure, identify the structure in Step 6, if this presynaptic neuron is cholinergic. What if the neuron is adrenergic? 10)

In 40 words or fewer, explain what an enzyme cascade is in the context of signal transduction pathways, and why these might be beneficial to the organism.

Describe the importance of ubiquitin-dependent degradation of soluble proteins.

So, what are the examples of regulators for each of the levels (A, B, and C)?

what the molcular and cellular aspected of this inhibitor?

Substrate binding causes dimerization of tyrosine kinase receptors. Why is dimerization critical to activate of the receptors?
