Multiple Choice
In eukaryotic cells, which organelle contains hydrolytic enzymes responsible for intracellular degradation?
A
Golgi apparatus
B
Lysosome
C
Rough endoplasmic reticulum
D
Mitochondrion
Verified step by step guidance1
Understand the function of each organelle listed: The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell.
Recall that the rough endoplasmic reticulum (RER) is primarily responsible for the synthesis of proteins destined for membranes or secretion, characterized by ribosomes on its surface.
Recognize that mitochondria are the powerhouses of the cell, generating ATP through cellular respiration but not involved in degradation processes.
Identify that lysosomes are membrane-bound organelles containing hydrolytic enzymes capable of breaking down various biomolecules, thus responsible for intracellular degradation.
Conclude that the organelle containing hydrolytic enzymes for intracellular degradation in eukaryotic cells is the lysosome.
