Peroxisome vs. lysosome functions
Which organelle begins the breakdown of very-long-chain fatty acids and both produces and degrades hydrogen peroxide?
Answer A: explanation for every choice
A
Correct. Peroxisomes shorten very-long-chain fatty acids and use catalase to break down the H2O2 they produce.
B
Lysosomes digest macromolecules with acid hydrolases.
C
Smooth ER synthesizes lipids and steroids and detoxifies drugs.
D
The Golgi modifies, sorts, and packages proteins.
TakeawayPeroxisomes: very-long-chain fatty acids, H2O2, catalase.
