Explain how the antidiuretic hormone can help regulate hypotension. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac). B 1 U Ꭶ Paragraph Arial V > 10pt Saved In the Research Article, how did the authors select the ~50 candidate genes to test with electrophysiology to determine if the genes might serve as a proton channel for sour sensing? A. Candidate genes were those that caused a decrease in proton currents in PKD2L taste receptor cells, when the gene was knocked-out B. Candidate genes were all those encoding evolutionarily conserved proteins with transmembrane regions O c. They considered all known proton channels as candidate genes for sour sensing in PKD2L taste receptor cells.
