Multiple Choice
In the context of Golgi processing and transport, which organelle is commonly described as the cell’s “post office” because it modifies, sorts, and ships proteins and lipids to their destinations?
A
Golgi apparatus
B
Mitochondrion
C
Rough endoplasmic reticulum
D
Lysosome
Verified step by step guidance1
Understand the role of each organelle listed in the problem: Mitochondrion, Rough endoplasmic reticulum, Lysosome, and Golgi apparatus.
Recall that the mitochondrion is primarily responsible for energy production through cellular respiration, not protein processing or sorting.
Recognize that the rough endoplasmic reticulum (RER) is involved in the synthesis of proteins, especially those destined for secretion or membrane insertion, but it does not perform extensive modification or sorting.
Know that lysosomes are involved in degradation and recycling of cellular waste, not in processing or shipping proteins and lipids.
Identify the Golgi apparatus as the organelle that modifies proteins and lipids received from the RER, sorts them, and packages them into vesicles for transport to their final destinations, which is why it is often called the cell’s 'post office'.
