The mitochondria of a cell are the centers of oxidative phosphorylation in aerobic organisms. Certain compounds have been found to perturb the proton gradient created during energy metabolism causing an increase or decrease in the consumption of oxygen by a colonial hydroid. Azide, an inhibitor has been shown to decrease the consumption of oxygen while dinitrophenol, an uncoupler, has been shown to increase oxygen consumption. In colonial hydroids on non-feeding days, the gastrovascular flow of the colonies is inactive and the mitochondria are less responsive to environmental cues such as the presence of these compounds. Therefore, larger concentrations of the compounds on non-feeding days were required to induce an evident physiological response by the colonies.
