1 Rate of O2 consumption in mitochondria is limited by the availability of ADP as a substrate for phosphorylation. 2  this dependence on ADP as a Pi acceptor is called acceptor control of respiration. 3  acceptor control ratio is the ratio of max rate ADP induced O2 consumption to the basal rate in the absence of ADP.
Aqua means water and some examples are: Aquatic Aquarium Aqueduct and aqueous.
An aquanaut is distinct from a submariner, in that a submariner is confined to a moving underwater vehicle such as a submarine that holds the water pressure out. Aquanaut derives from the Latin word aqua (water) plus the Greek nautes (sailor), by analogy to the similar construction astronaut.
