the presence of 0.5 mM glucose induced total hexokinase activity in supernatants from sperm extracts of 1.7 mIU/mg protein, while the same concentration of both fructose, mannose, and sorbitol induced total hexokinase activity from 0.3 mIU/mg protein to 0.60 IU/mg protein. Diluted boar sperm from fresh ejaculates phosphorylates glucose through the hexokinase step much more efficiently than fructose or mannose. This difference facilitates a much more rapid intake of glucose into glycolysis than the other sugars
