Apparent respiratory quotient observed in headspace of static respirometers underestimates cellular respiratory quotient of pear fruit

Measurement of the Respiratory Quotient of Peat

The Respiratory Quotient of Frog Nerve During

Some experiments have recently been described (Fenn, 1927) which successfully demonstrated an increased oxygen consumption of the nerves of dogfish and frogs during stimulation, thus confirming Tashiro (1913) and Parker (1924-25) who measured CO2 output as well as Downing, Gerard, and Hill (1926) and Gerard (1927, a and b) who measured heat production. The apparatus, a differential volumeter, c...

The respiratory quotient in the newborn pig.

I . Rates of oxygen consumption and carbon dioxide production were measured in pigs from birth to 3 days of age in an open-circuit system. 2. The mean respiratory quotient (RQ) during the first 6 h following birth was 0.95 in fasted pigs and 0.91 in pigs which were allowed to feed. 3. The RQ fell during the remainder of the first postnatal day to mean values close to 0.85, whether the pigs were...
