Golgi Processing and Transport
Multiple Choice
In an animal cell, what is a primary function of the Golgi apparatus in processing and transport?
A
It is the main site of translation by assembling amino acids into polypeptides on ribosomes.
B
It modifies (e.g., glycosylates), sorts, and packages proteins and lipids into vesicles for secretion or delivery to specific organelles.
C
It synthesizes most cellular ATP through oxidative phosphorylation on inner membrane cristae.
D
It replicates nuclear DNA and segregates chromosomes during mitosis.
Verified step by step guidance1
Identify the role of the Golgi apparatus within the cell by recalling its main functions related to protein and lipid processing.
Understand that the Golgi apparatus receives proteins and lipids from the endoplasmic reticulum and then modifies them, such as by adding carbohydrate groups (glycosylation).
Recognize that after modification, the Golgi apparatus sorts these molecules and packages them into vesicles.
Know that these vesicles are then directed either to the cell membrane for secretion or to specific organelles within the cell for their functional roles.
Differentiate the Golgi apparatus functions from other organelles: ribosomes (protein synthesis), mitochondria (ATP production), and nucleus (DNA replication and chromosome segregation).
