Lysosomal and Degradation Pathways
Multiple Choice
In the context of lysosomal and degradation pathways, which organelle is best described as an organelle containing digestive (hydrolytic) enzymes that break down macromolecules?
A
Peroxisome
B
Mitochondrion
C
Lysosome
D
Rough endoplasmic reticulum
Verified step by step guidance1
Understand the function of each organelle listed: Peroxisomes are involved in lipid metabolism and detoxification, mitochondria generate ATP through cellular respiration, rough endoplasmic reticulum synthesizes proteins, and lysosomes contain digestive enzymes.
Recall that lysosomes are membrane-bound organelles filled with hydrolytic enzymes capable of breaking down macromolecules such as proteins, lipids, nucleic acids, and carbohydrates.
Recognize that the key feature of lysosomes is their role in degradation and recycling of cellular waste, which distinguishes them from the other organelles listed.
Connect the description of an organelle containing digestive enzymes that break down macromolecules directly to the lysosome based on its biological function.
Conclude that among the options given, the lysosome is the organelle best described as containing digestive (hydrolytic) enzymes responsible for breaking down macromolecules.
