Compare the structure and function of lysosomes and peroxisomes
What will be an ideal response?
Lysosomes serve as the intracellular digestive system. They contain hydrolytic enzymes and, in addition to breaking down raw ingredients, they also remove worn-out organelles.
Peroxisomes contain oxidative enzymes and perform detoxifying activities by removing hydrogen atoms from certain organic molecules. Lysosomes serve as the intracellular digestive system. They contain hydrolytic enzymes, and in addition to breaking down raw ingredients, they also remove worn-out organelles.
