Abstract
The Michaelis-Menten constant (KM) of fructose and of glucose as substrate for bull spermatozoa has been measured: fructose KM = 1.04 [image], glucose KM = 0.06 [image]. The saturation rate of fructose utilization was found to be 1.8 times that of glucose utilization. This is in general agreement with characteristics of hexokinases extracted from different sources.This publication has 9 references indexed in Scilit:
