摘要: Publisher Summary This chapter discusses overall metabolic features associated with cells of the testis and ovary, emphasizing abrupt transitions that occur in spermatogenesis, epididymal maturation, oogenesis, fertilization, early development. Fertilization results fusion two haploid cells, each relatively simplified needs, to form a diploid ovum. It is found subsequent cell divisions biosynthesis all necessary organelles specialized proteins reintroduce complexity metabolism reproductive cycle. ATP synthesis, derived by host different transformations carbon compounds cellular environment, accomplished coupling oxidation/ reduction reactions few key enzyme systems. Substrates satisfy spermatozoal generation can be from either exogenous materials or endogenous materials. A comparison turnover cauda ejaculated bull sperm presented. rabbit used reserves unknown 30%–50% total need, deriving balance extracellular glucose supplied medium. The effect decreased temperature on also elaborated.
