Degradation of a peroxisome by micropexophagy. Degradation of a mitochondrion by microautophagy. The transfer of cytosolic components into the lysosomal compartment by direct invagination of the lysosomal membrane without prior sequestration into an autophagosome. The engulfing membranes fuse, resulting in the lysosomal delivery of the cargo wrapped in a single membrane derived from the invaginated lysosomal membrane. In S. cerevisiae, the vacuole is the lysosomal compartment. The process by which cells digest parts of their own cytoplasm; allows for both recycling of macromolecular constituents under conditions of cellular stress and remodeling the intracellular structure for cell differentiation. Degradation of a cell nucleus by microautophagy. The chemical reactions and pathways resulting in the breakdown of substances, carried out by individual cells. A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a membrane. A membrane is a double layer of lipid molecules that encloses all cells, and, in eukaryotes, many organelles; may be a single or double lipid bilayer; also includes associated proteins. The infolding of a membrane, resulting in formation of a vesicle.
