Autophagosomes fuse with lysosomes2
  • During bulk autophagy, autophagosomes fuse with lysosomes or vacuoles resulting in the degradation of the cargo. (hypothes.is)
  • In the autophagic process, part of the cytosol or organelles is first enclosed by double-or multiple-membrane structures called \u0027autophagosome\u0027.Eventually, the autophagosomes fuse with lysosomes and the sequestered contents and the inner membranes are degraded by lysosomal hydrolases. (soken.ac.jp)
Autophagosome9
