Concerning penile erection, which of the following statements is incorrect?
a) The parasympathetic nervous system releases nitric oxide |
|
b) Nitric oxide activates a G-protein coupled receptor which generates cGMP |
|
c) Cytosolic level of cGMP increases |
|

|
b) H+ is secreted across the basolateral membrane of the parietal cell by the H+-K+-ATPase |
|
c) HCO3- leaves the parietal cell at the basolateral membrane, and its downhill efflux powers the uphill entry of Cl- into the parietal cell |
