Which description of synapses is not correct? which description of synapses is not correct? second messengers can activate gene
activities in the postsynaptic neuron. excitatory synapses cause depolarization. direct signaling involves the activation of g proteins. ionotropic receptors are ion channels that open and influence the polarization of the membrane?
The incorrect among the choices is "<span>direct signaling involves the activation of g proteins"
This is incorrect because direct signaling does not involve the activation of g proteins rather it involves the activation of ion channels resulting to either an excitation reaction (depolarization of the membrane) or an inhibition reaction (hyperpolarization of the membrane); and this will ultimately affect the action of the organ the nerve is innervating.</span>
I would like to believe that the answer to this question is the third option which is direct signaling involves the activation of G proteins. <em />In direct signaling ion channels that affect the polarization of the membrane are opened. The direct signaling pathway is local and therefore 2-AG binds only with a few neighboring synapses.
Imagine that a person has a disorder of the pancreas that does not allow it to secrete digestive enzymes. The breakdown of the macromolecule would be <span>affected the most by this disorder. The macromolecule is called the "Nucleic Acids."</span>
The waves of a seashore hit the sand, because of the moon the tide lowers and rises. when it lowers the tide pool only has some water and a lot of oxygen when the tide rises it has less oxygen.
