Abstract

The rate of incorporation of [3H]glucose into glycogen was determined in bullfrog retina incubated in vitro in dark and in the light. The rate of incorporation for glucose was found to be approximately two-fold greater in the dark than in the light, 0.108 vs. 0.061 nmol mg-1 protein min-1, respectively. The turnover rate for glycogen was found also to be approximately two-fold greater in the dark than in the light, 0.051 vs. 0.027% min-1, respectively.

摘要

在黑暗和光照条件下对牛蛙视网膜进行体外培养，测定了[3H]葡萄糖掺入糖原的速率。结果发现，黑暗条件下葡萄糖的掺入速率约为光照条件下的两倍，分别为0.108和0.061 nmol mg-1蛋白质每分钟。糖原的周转率在黑暗条件下也约为光照条件下的两倍，分别为0.051和0.027%每分钟。
