Mostly occurring under starvation conditions, for 10 points, name this process in which a cell degrades its own components.
In polio-infected cells, this process is mimicked by vesicles that are tagged with cephalin-modified LC3. It's not differentiation, but it is upregulated by beclin 1, which suppresses a competing process. It is also downregulated by Tor, via UNC-51-like kinases. In Alzheimer's, multilamellar bodies may generate amyloid-beta as a byproduct of this process. This process occurs in structures that are synthesized at omegasomes on the ER, where Atg is localized. The organelle in which this process occurs is enclosed by the isolation membrane, or (*) phagophore. Acid hydrolases carry out this process in an organelle that is produced by the fusion of a namesake vesicle with a lysosome.
