C3 Lysosome Flashcards
1
Q
What is a lysosome?
A
A membranous sac of hydrolytic enzyme that can digest macromolecules.
2
Q
In what pH does lysosomal enzymes works best in?
A
Acidic.
3
Q
Where were lysosomal enzymes and lysosomal membranes made from?
A
Made in the rough ER and further modified in Ga.
4
Q
What are the two functions of lysosomes?
A
Intracellular digestion and autophagy.
5
Q
Elaborate the process of intracellular digestion.
A
A lysosome fuses with a food vacuole and hydrolytic enzyme digests the food. Eg: lysosomes in macrophage contain enzymes that digests bacteria. Amoeba digest food by using enzyme from lysosome.
6
Q
Explain autophagy.
A
Lysosomes use enzymes to digest cell’s own organelles. Hydrolytic enzymes digest the organelles and its components are recycled.
