Abstract: Ram and bull spermatozoa oxidize acetate faster than or similarly to glucose, while dog and rabbit spermatozoa oxidize glucose faster than acetate; rabbit spermatozoa, in particular, have hardly any capacity to oxidize acetate. Glucose and fructose are oxidized at about the same rate by the spermatozoa of all four species, each sugar giving rise to similar amounts of lactate. Lactate is readily oxidized by spermatozoa of all four species; with rabbit and dog spermatozoa the rate of lactate oxidation greatly exceeds that of glucose, fructose, pyruvate or acetate. Pyruvate is oxidized by ram and bull spermatozoa faster than acetate. With dog and rabbit spermatozoa, the recovery of 14CO2 from [1-14C]pyruvate is 2 to 4 times that from [2-14C] or [3-14C]pyruvate; this may be due to a dismutation of pyruvate. |
