Abstract: 
Using ultracytochemical methods, the presence of Na+, K+-activated ATPase during oocyte development in H. formosa was studied. ATPase was discovered in all 4 oocyte stages, but its level was highest in stages II and III in which yolk formation took place. Na+, K+-activated ATPase was found on the membranes of both the yolk vesicles and the cortical granules and on the oocyte and follicular microvilli and the primary oocyte membrane; the microvilli were the sites of substance exchange between the follicle and the oocyte.
