Multiple Choice
In eukaryotic cells, what do lysosomes and the Golgi apparatus have in common?
A
Both contain their own DNA and ribosomes and can replicate independently of the nucleus
B
Both are membrane-enclosed organelles that are part of the endomembrane system and participate in processing and trafficking of cellular materials
C
Both are the primary sites of ATP production through oxidative phosphorylation
D
Both are double-membrane organelles specialized for photosynthesis and carbon fixation
Verified step by step guidance1
Step 1: Identify the key features of lysosomes. Lysosomes are membrane-enclosed organelles containing digestive enzymes that break down macromolecules, old organelles, and foreign substances within the cell.
Step 2: Identify the key features of the Golgi apparatus. The Golgi apparatus is a membrane-bound organelle involved in modifying, sorting, and packaging proteins and lipids received from the endoplasmic reticulum for transport to their destinations.
Step 3: Understand the endomembrane system. Both lysosomes and the Golgi apparatus are part of the endomembrane system, which is a group of interconnected organelles that work together to modify, package, and transport lipids and proteins within the cell.
Step 4: Compare the options given. Lysosomes and the Golgi apparatus do not contain their own DNA or ribosomes, so they cannot replicate independently of the nucleus. They are not involved in ATP production (which occurs in mitochondria), nor are they double-membrane organelles specialized for photosynthesis (which describes chloroplasts).
Step 5: Conclude that the commonality between lysosomes and the Golgi apparatus is that both are membrane-enclosed organelles within the endomembrane system that participate in processing and trafficking cellular materials.
