[Independence of the (NAD+):(NADH) ratio from the adenylic system in the liver cytoplasm of the developing chick embryo]
Abstract
No dependence was found between the index of the adenylic system phosphorylated state (ATP) : (ADP) (HPO2-4), the ratios (ATP) : (ADP) and (ATP : (ADP + AMP), on one hand, and the ratio (NAD+) : (NADH) in the cytoplasm, on the other one. The maximum value of the ratio (ATP) : (ADP) (HPO2-4) was observed on the 17th day of development and correlated with the maximum rate of gluconeogenesis. The ratio (NAD+) : (NADH) in the cytoplasm suffered no changes until hatching and decreased twice thereafter.
