What is an autophagolysosome?
An autophagolysosome is a cellular compartment formed through the fusion of an autophagosome (which contains cellular material targeted for degradation) with a lysosome (the cell's recycling center). This fusion enables the breakdown of the autophagosome contents by lysosomal enzymes, providing the cell with nutrients and helping maintain cellular homeostasis.
What is the recycling of worn out organelles?
The recycling of worn-out organelles in a cell is primarily carried out by a process called autophagy. During autophagy, the cell engulfs the organelles in a specialized vesicle called an autophagosome, which then fuses with lysosomes where the organelles are broken down and their components are reused for new cellular activities. This process helps maintain cellular homeostasis and ensures efficient utilization of resources.
What is the double membrane that eventually surrounds the organelle that is targeted for degradation during autophagy?
autophagosome

What are the structures within a cell sometimes surrounded by a membrane called?
The nucleus, mitochondria, endoplasmic reticulum, vacuole, lysosome, autophagosome, Golgi, transport vesicle, endosome, exosome.
Do lysosomes participate in autophagy?
Yes, lysosomes play a crucial role in autophagy. They fuse with autophagosomes, which are vesicles that contain cellular debris or organelles targeted for degradation. Once fused, lysosomal enzymes break down the contents of the autophagosome, recycling essential molecules for the cell.
What breaks down worn-out organelles?
Worn-out organelles are broken down by a process called autophagy. Autophagy involves the formation of a double-membraned vesicle called an autophagosome that engulfs the organelle and fuses with a lysosome, where the organelle is degraded by enzymes.
When cell parts such as organelles break down they are recycled by what?
Cell parts such as organelles are recycled by the process of autophagy, where the damaged components are engulfed by a double membrane structure called an autophagosome and targeted for degradation by lysosomes. This process helps maintain cellular health by clearing out dysfunctional organelles and recycling their components for reuse.

How does a cell rid itself of defective of malfunctioning organelles?
Cells can rid themselves of defective or malfunctioning organelles through a process called autophagy. This involves the formation of a double-membrane structure called an autophagosome, which engulfs the damaged organelles and delivers them to lysosomes for degradation. The breakdown products are then recycled for reuse by the cell.
