Lysosomes

ID #1966

I understand that phagolysosomes in autophagy and phagocytosis degrade organelles, macromolecules, bacteria. I also have written down that what they degrade are used as building blocks to make new macromolecules. I'm not sure if I have this info down correctly. If it is correct, does this mean that vesicles can bud off the lysosome and transport the degraded material somewhere else to be used?


   

What you heard that day was that when a protein gets broken down in a lysosome, it yields amino acids, right? Likewise, when a polysaccharide is degraded, monosaccharides are released. These monomers can be exported through special protein channels (passages) in the lysosomal membrane and then you've got "fresh" building blocks to make new proteins, carbohydrates, etc.
