Abstract
Hexokinase activity was detected in cytosols and homogenates from different developmental stages of Bufo bufo embryos starting from stage 17. Free glucose was measured in the embryo cytosol and was detected at each stage tested. At stage 15, a large increase of glucose content of the embryo cytosol occurs. Hexokinase expression in the embryo thus occurs after the increase of cytosol glucose content occurring at stage 15. The findings rule out that glucose by itself is the hexokinase inducer in vivo. The very low glucose utilization found by many authors during early amphibian development may be related to the late hexokinase expression during Bufo bufo development.
