<h2>Nicotinic ACh</h2>

Explanation:

  • They serve differing and regularly basic capacities all through the focal and fringe sensory systems, and have developing jobs in non-neuronal systems, .  
  • The synapse acetylcholine (ACh) can direct neuronal edginess by following up on the cys-circle cation-leading ligand-gated nicotinic ACh receptor channels (nAChRs).
  • These receptors are broadly disseminated all through the focal sensory system, being communicated on neurons and non-neuronal cells, where they take part in an assortment of physiological reactions, for example, uneasiness, the focal handling of torment, nourishment consumption, nicotine looking for conduct, and psychological capacities.
  • In the mammalian cerebrum, nine distinct subunits have been discovered up to this point, which amass into pentameric edifices with much subunit decent variety; anyway the α7 and α4β2 subtypes prevail in the CNS.

Explanation:

PKA and PKG is both have binding domains to attach with nucleoside monophosphate and help in modulating these enzymes that explains that PKA is more related to the PKG than PKC at the level of amino acid.

At the level of  polypeptide chain level PKG has single polypeptide chain whereas in PKA modulatory domains are located on different poly peptide chain. Both are activated by the nucluoside triphosphate, more precisely PKA by cAMP and PKG is by cGMP respectively, whereas PKC is activated by DAG or Ca or both depending on the isofom.

Thus, the correct answer is - option B.

DIA [1.3K]
Meiosis occurs in a series of different phases and creates genetically unique reproductive cells. The process which helps make meiotic cells genetically different and occurs during prophase I, but not during prophase II, is crossing over (C). Crossing over is the exchange of genetic material between two homogenous chromosomes. It is one of the final phases of prophase I. This process is called synapsis. It occurs when the matching regions on the matching chromosomes break and then reconnect to the other chromosome
