Question

question 18 (2.5 points)
which organelle has enzymes that break down fatty acids, amino acids, and toxins?
lysosomes
peroxisomes
golgi bodies
vacuoles
rough er

Explanation:

• Lysosomes are mainly for digesting macromolecules like proteins, nucleic acids, etc.
• Peroxisomes contain enzymes that break down fatty acids (via beta - oxidation), amino acids, and detoxify harmful substances (e.g., hydrogen peroxide).
• Golgi bodies are involved in modifying, sorting, and packaging proteins and lipids.
• Vacuoles are for storage (e.g., water, nutrients) and maintaining turgor pressure in plant cells.
• Rough ER is associated with protein synthesis (due to ribosomes on its surface).

Answer:

peroxisomes
