moreover , the li subpopulation , significantly enriched in organelles of 0.03-0.25 micron diameter ( simon et al . [ 25 ] , exhibits a higher acid phosphatase activity/beta-galactosidase activity ration than lt. it is suggested that 1 ) endocytosis is not preferential for newly iodinated tg , 2 ) the thyroid lysosomes hydrolyse preferentially recently iodinated tg , 3 ) tg enters the cell by micropinocytosis , 4 ) the micropinocytotic vesicles fuse rapidly with primary lysosomes , 5 ) progressive release of iodinated compounds occur during the maturation of secondary lysosomes which fuse amongst themselves .
