The endoplasmic reticulum (ER) is found throughout the cytoplasm and plays a critical role in cell metabolism.
What is the primary purpose of the greatly increased surface area it provides?
Correct Answer
Enzymes involved in chemical reactions, particularly protein synthesis
Explanation
The endoplasmic reticulum (ER) is a series of double-layered membranes found throughout the cytoplasm. It greatly increases the surface area available for enzymes involved in chemical reactions, particularly those leading to protein synthesis. It also forms a multibranched channel connecting the cell membrane and nuclear membrane, expediting transport of cellular materials.
