Question 40

Briefly state the functions of the rough and smooth endoplasmic reticulum.

Answer 40

The rough endoplasmic reticulum synthesizes glycoproteins, phospholipids and digestive enzymes that are transferred to other cellular organelles, inserted into the plasma membrane, secreted during exocytosis or stored in the lysosomes. The smooth endoplasmic reticulum synthesizes fatty acids and steroids, detoxifies harmful substances, removes phosphate groups from glucose-6-phosphate, and stores and releases calcium ions that trigger contractions in muscle fibers
