Multiple Choice
Which of the following is a primary function of the Golgi apparatus in eukaryotic cells?
A
Degrading macromolecules using hydrolytic enzymes within lysosomes
B
Translating mRNA into polypeptides using ribosomes bound to the rough endoplasmic reticulum
C
Modifying and sorting proteins and lipids for secretion or delivery to other organelles
D
Synthesizing ATP via oxidative phosphorylation on the inner mitochondrial membrane
Verified step by step guidance1
Identify the main functions of each organelle mentioned in the options to understand their roles in the cell.
Recall that the Golgi apparatus is primarily involved in processing and packaging macromolecules like proteins and lipids after they are synthesized.
Understand that the Golgi modifies proteins and lipids by adding carbohydrate groups or other molecules, which is essential for their proper function and targeting.
Recognize that the Golgi sorts these modified molecules and directs them to their correct destinations, such as secretion outside the cell or delivery to other organelles.
Compare this with other organelles: lysosomes degrade macromolecules, ribosomes translate mRNA into proteins, and mitochondria synthesize ATP, confirming that the Golgi's primary function is modification and sorting.
