Therefore, lysosomes are comparable to recycling plants ... Physiological Roles of Autophagy How much and what parts of the cell can be eaten without causing cell death? Scientists hypothesized ...

Lysosomes break down macromolecules into their constituent parts, which are then recycled. These membrane-bound organelles contain a variety of enzymes called hydrolases that can digest proteins ...

Lastly, in autophagy, the cell cleans up its own damaged parts, such as old mitochondria, by wrapping them in a membrane bubble called an autophagosome. This bubble then merges with the lysosome ...
