title: [Respiration and glycolysis in the liver of developing chick embryos and chicks].
abstract: Oxygen uptake in liver slices remains constant between the 12th and the 17th days of embryonic development, being equal to that in 30-60-day chicks. During the transition from allantoic respiration to the pulmonary one, oxygen consumption decreases, the decrease being observed up to the end of embryonic period. After hatching, oxygen consumption increases 4-5-fold to the 6-7th and decreases up to the initial level at the 10th day. Respiration of mitochondria isolated from the liver and concentration of cytochromes in mitochondria remain constant. The value P/O is the lowest, whereas catalase activity is the highest during hatching. The intensity of anaerobic glycolysis changes similarly to that of respiration.
