41. Upon release, the enzymes are ferried to their final destination in the lysosomes . 42. Lysosomal enzymes from being secreted and to ensure they are targeted to the lysosome . 43. It is targeted to CD63 positive secretory lysosomes . 44. LRP2 functions to mediate endocytosis of ligands leading to degradation in lysosomes or transcytosis. 45. Cathepsin D is an aspartic endo-protease that is ubiquitously distributed in lysosomes . 46. Amino acid availability determines RPTOR targeting to lysosomes . 47. Upon detachment from the membrane, these enzymes are cleaved and degraded within lysosomes . 48. In 1969 he gave the first clear-cut distinction between lysosomes and peroxisomes. 49. Like lysosomes of animal cells, vacuoles have an acidic pH and contain hydrolytic enzymes. 50. The lysosome engulfs another organelle and uses its enzymes to take apart the ingested material.
