Lysosoma

Schema cellulae typicae animalis, partes subcellulares ostendens. Organella: (1) nucleolus, (2) nucleus, (3) ribosoma, (4) vesicula, (5) reticulum endoplasmaticum granulosum, (6) apparatus Golgianus, (7) cytosceletus, (8) reticulum endoplasmaticum leve, (9) mitochondria, (10) vacuola, (11) cytoplasma, (12) lysosoma, (13) centriola.

Lysosoma^[1] (-atis, n.) (ex verbis Graecis λύσις solutio et σῶμα corpus compositum) est organellum in cellulis animalibus inventum, quod enzyma hydrolytica includit, ut materias vastas et reliquias cellulares dissolvat. In fermentis^? et plantis, vacuola lytica eandem functionem gerunt.^[2]

FormatioRecensere

In exordio omnis lysosomatis primo pars systematis endomembranosis in vesiculam formatur (lysosoma primarium), deinde in apparatu Golgiano enzymos in reticulo endoplasmatico fabricatos (hydrolases) otbinet. Paulo ante hanc conexionem mannosum-6-phosphatum accepit. Per fusionem cum endosomate sero (pH 5.5) tandem fit lysosoma maturum.
