Lysosoma

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]

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.

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.
