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.
