1.5 Cell Organelles DSA Flashcards
1
Q
Where are the digestive enzymes found in the Lysosomes synthesized?
Where are they packaged and labeled?
A
In the Rough Endoplasmic Reticulum
In the Golgi Apparatus
2
Q
What molecule serves as a tag for these digestive enzymes?
A
Mannose 6 Phosphate
3
Q
What do digestive enzyme stuffed golgi vesicles bond to to form a lysosome?
What is it that activates the digestive enzymes?
A
A late endosome.
The acidic environment of the late endosome dissociates the Mannose 6 Phosphate tags, activating the digestive enzymes.
4
Q
What maintains the acidic environment inside lysosomes?
A
H+ ATPase
5
Q
What is Crinophagy?
A
When a lysosome digests a cell’s excess secretory product (like a hormone for a hormone producing cell)
6
Q
What enzyme do peroxisomes use to break down H2O2?
A
Catalase
