Pre- and post-natal hepatic glucose phosphorylation in chicks (Gallus domesticus).
1. Hepatic glycogen levels and activities of metabolic enzymes were measured 7 d and 2 d before hatching, immediately after hatching and 4 d thereafter. 2. Chicken liver has a particle-bound hexokinase with a high K(m) (8 mM) for glucose. 3. The results indicate that the high-K(m) hexokinase is involved in the mitochondrial generation of ATP for glycogen and lipid synthesis.
