Ammonia excretion in mytilid mussels is facilitated by ciliary beating

Ammonia excretion in mytilid mussels is facilitated by ciliary beating.

The excretion of nitrogenous waste products in the form of ammonia (NH3) and ammonium (NH4 (+)) is a fundamental process in aquatic organisms. For mytilid bivalves, little is known about the mechanisms and sites of excretion. This study investigated the localization and the mechanisms of ammonia excretion in mytilid mussels. An Rh protein was found to be abundantly expressed in the apical cell ...

Proton-facilitated ammonia excretion by ionocytes of medaka (Oryzias latipes) acclimated to seawater.

The proton-facilitated ammonia excretion is critical for a fish's ability to excrete ammonia in freshwater. However, it remains unclear whether that mechanism is also critical for ammonia excretion in seawater (SW). Using a scanning ion-selective electrode technique (SIET) to measure H(+) gradients, an acidic boundary layer was detected at the yolk-sac surface of SW-acclimated medaka (Oryzias l...
