How are senescent organelles broken down in the cell?

Destroyed in phagosomes and regulated by autophagy (Atg) genes. Obsolete organelles are corralled by invaginations of the plasma membrane, marked with LC3 protein, which fuses with lysosomes

Destroyed in lysosomes and regulated by autophagy (Atg) genes. Obsolete organelles are corralled by double membrane vesicles derived from the endoplasmic reticulum, marked with LC3 protein, which fuses with lysosomes

Destroyed in lysosomes and regulated by autophagy (Atg) genes. Obsolete organelles are corralled by double membrane vesicles derived from the endoplasmic reticulum, marked with LC3 protein, which is the transported to the plasma membrane and expelled by exocytosis
