Multiple Choice
In eukaryotic cells, what is the primary function of the Golgi apparatus in protein and lipid trafficking?
A
It synthesizes ATP through oxidative phosphorylation on its inner membrane.
B
It modifies, sorts, and packages proteins and lipids into vesicles for secretion or delivery to other organelles.
C
It is the site of ribosomal RNA transcription and ribosome subunit assembly.
D
It replicates genomic DNA and assembles nucleosomes during S phase.
Verified step by step guidance1
Identify the role of the Golgi apparatus in the cell by recalling its main functions related to proteins and lipids.
Understand that the Golgi apparatus receives proteins and lipids from the endoplasmic reticulum (ER) and processes them.
Recognize that the Golgi modifies these molecules, for example by adding carbohydrate groups (glycosylation) or other chemical modifications.
Know that after modification, the Golgi sorts and packages these proteins and lipids into vesicles.
These vesicles then transport the molecules either to the cell surface for secretion or to other organelles within the cell.
