... (J v ) as previously observed with crude extracts of corpus cardiacum and with cyclic AMP. Unlike cyclic AMP, Scg-ITP does not stimulate ileal NH 4 + secretion. H + secretion (J H ) in the ileum, which is not affected by cyclic AMP, is almost completely abolished by Scg-ITP. Although ITP may act via...

...Brian J. Harvey ABSTRACT The frog skin in vivo is capable of active transepithelial H + secretion (JH) which is matched by Na + absorption ( J NA ). Studies in vitro demonstrate that J H is generated by an H + -ATPase pump localized in apical membranes of mitochondria-rich (MR) cells, whereas J Na...
