6.4 lysosomes Flashcards
1
Q
a lysosome is
A
a membranous asac of hydrolytic enzymes that an animal cell uses to digest macromolecules
–they work best in acidic environments
2
Q
where are the hydrolytic enzymes and the lysosomal membrane made
A
the rough ER
-then transferred to golgi for further processing
3
Q
what keeps the enzymes and membrane from being destroyed
A
their 3D shape
4
Q
how do lysosomes digest things
A
phagocytosis
- engulfing smaller organisms and food particles
- lysosomes fuse with the food vacuole whose enzymes digest he food
5
Q
autophagy
A
where lysosomes recycle organic material
-the broken organelle is surrounded by a double membrane and the lysosome breaks it down into usable monomers
