Functions of Endoplasmic Reticulum

Medium Biology Cellular Biology

In cellular biology, the structure and function of various organelles are crucial for understanding how cells operate. One important organelle is the endoplasmic reticulum (ER), which plays a significant role in protein and lipid synthesis. The ER comes in two types: rough and smooth. The rough ER is studded with ribosomes, while the smooth ER lacks these ribosomes. These differences in structure correlate with their respective functions. Considering the functions of the rough and smooth endoplasmic reticulum, which of the following statements is most accurate?

The rough endoplasmic reticulum primarily synthesizes lipids, while the smooth endoplasmic reticulum synthesizes proteins.

The smooth endoplasmic reticulum is involved in detoxifying harmful metabolic byproducts, while the rough endoplasmic reticulum is responsible for protein synthesis.

The rough endoplasmic reticulum mainly stores calcium ions, while the smooth endoplasmic reticulum processes steroids.

Both types of endoplasmic reticulum are primarily involved in protein synthesis.
