In which cellular compartment are lipids synthesized?
A
Nucleus
B
Endoplasmic Reticulum
C
Golgi
D
Vesicles
Verified step by step guidance1
Understand the role of each cellular compartment listed in the options: Nucleus, Endoplasmic Reticulum, Golgi, and Vesicles.
Recall that the Endoplasmic Reticulum (ER) is a major site for lipid synthesis in the cell, particularly the smooth ER, which is involved in the synthesis of lipids and steroids.
Consider the function of the Golgi apparatus, which is primarily involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell, rather than synthesizing them.
Recognize that vesicles are involved in the transport of materials within the cell and do not synthesize lipids themselves.
Conclude that the Endoplasmic Reticulum is the correct cellular compartment for lipid synthesis, as it is specifically equipped for this function, unlike the other options.
