Peroxisomal matrix vs membrane proteins
Peroxisomal Targeting Signals (PTS1 & PTS2)
Role of PEX proteins (Peroxins)
Receptor recycling mechanism
Difference between peroxisome and mitochondrial protein import
Import of folded proteins (unique feature of peroxisomes)

📌 Key Concepts:
Peroxisomes import proteins post-translationally using PTS1 (C-terminal SKL motif) and PTS2 (N-terminal signal) with the help of PEX5, PEX7, PEX14, PEX13.
👉 Watch till the end for exam tips and MCQ-oriented explanations.
