In eukaryotic cells, which organelle primarily modifies, sorts, and packages proteins for secretion or delivery to other cellular destinations?
A
Rough endoplasmic reticulum
B
Mitochondrion
C
Golgi apparatus
D
Lysosome
Verified step by step guidance1
Identify the function described in the question: modifying, sorting, and packaging proteins for secretion or delivery to other parts of the cell.
Recall the roles of the listed organelles: the rough endoplasmic reticulum (RER) is involved in protein synthesis and initial folding, mitochondrion is the powerhouse producing ATP, and lysosomes are involved in degradation and recycling.
Understand that after proteins are synthesized in the RER, they are transported to another organelle for further processing and packaging.
Recognize that the Golgi apparatus is the organelle responsible for modifying proteins (such as adding carbohydrate groups), sorting them, and packaging them into vesicles for secretion or delivery.
Conclude that the Golgi apparatus matches the described function, making it the correct answer.
