Question

All of the following are synthesized along various sites of the endoplasmic reticulum except one. Identify the exception.

a) fatty acids
b) proteins
c) steroids
d) RNA
e) phospholipids

Answer 1

Among the options provided, RNA is the component that is not synthesized along the endoplasmic reticulum but is synthesized in the nucleolus.

Step-by-step explanation:

All of the following are synthesized along various sites of the endoplasmic reticulum except one. The components that are synthesized along the endoplasmic reticulum are fatty acids, proteins, steroids, and phospholipids. The endoplasmic reticulum (ER) is divided into two types.

The RNA components of ribosomes are synthesized in the nucleolus, which is part of the cell nucleus, not the endoplasmic reticulum. The nucleolus is responsible for the assembly of ribosomal RNA (rRNA) which is then combined with proteins to form ribosomes. These ribosomes may attach to the Rough ER for protein synthesis.
