Oxygen consumption of tadpoles during metamorphosis

“…Huxley (1922), for instance, has suggested that the thyroid causes an increase in the rate of metabolism of all the tissues and that in these conditions certain organs develop whereas others are caused to atrophy.Several workers have tried to determine whether the rate of metabolism changes during metamorphosis, but their results have been contradictory. Abelin & Scheinfinkel (1923) found that C02 output usually fell during metamorphosis of Rana esculenta. Helif (1926) found that 02 consumption per gram wet weight increased in tadpoles of Rana pipiens during metamorphosis induced by treatment with diiodotyrosine.…”

The thyroid gland.

“…The Thyroid and Metabolism. Thyroid deficiency is characterized by low oxidative processes (1,8,80,112,146,147,149). This is true of the human myxedematous and cretinoid types as well as of the experimentally produced forms.…”
