Abstract
DNP (2,4-dinitrophenol) increases the O2 consumption and inhibits the ciliary beat of gill pieces from the mussel, Mytilus edulis L. The max. effect on O2 consumption occurred in the presence of 5 x 10-4 [image] DNP, a 50% inhibition of ciliary beat in 4 x 10-4 m DNP. The similarity of these effective concns. supports the theory that DNP "uncouples" the energy-utilizing steps of metabolism.
