An mGluR receptor on the postsynaptic cell membrane has a Go G-protein. If a neurotransmitter causes receptor activation and then Go causes a sodium channel to close, what influence is this action likely to have on membrane potential in the postsynaptic cell? Nn - A hyperpolarizing influence What is a metabotropic receptor? - a type of membrane receptor of eukaryotic cells that acts through a second messenger. What is convergence of neural input ? - several presynaptic neurons synapse with ...

PSIO 303 Exam Practice Test with Complete Solutions Which of the following is an accurate statement about signal transduction? A. A chemical messenger produced by one cell in a tissue that acts on an adjacent cell in the tissue is an example of endocrine communication. B. Only the amino acids tyrosine, serine, and alanine in signaling proteins undergo phosphorylation and dephosphorylation. C.

PSIO 303 EXAM 1 TEST QUESTIONS AND ANSWERS (100% SCORE) Why would cells have a tendency to swell? - Answer️️ -Because cytoplasm contains negatively charged proteins that cannot exit, so cells naturally gain water and swell What prevents cells from actually swelling? - Answer️️ -It is effectively impossible for sodium to enter the cell (due to pump and lack of sodium channels). There is a high sodium ion concentration outside the cell which prevents water from entering in the cell...
