Question

Which of the following processes and organelles account for the replacement of lipids and proteins lost from the plasma membrane

Answer 1

Answer:

Vesicles (Exocytosis),RER (Rough ER) and SER(Smooth ER)

Explanation:

Vesicles are a small structure consisting of a lipid bilayer. They are form naturally during the process of secretion (exocytosis) and up take of nutrients (phagocytosis) and transport materials within the cytoplasm. Vesicles binds with the plasma membrane to release its content outside of cell.

Endoplasmic reticulum

It’s a series of interlinked sacs and tubules modifies proteins and synthesizes lipids.However, the synthesis of proteins and lipids carried out in two different regions of endoplasmic reticulum that is rough ER and Smooth ER. Ribosomes transfer their synthesize proteins into the lumen of the RER where they modify proteins. It also makes phospholipids for cellular membranes

The SER is continuous with the RER and its role is to synthesize lipids, carbohydrates, and steroid hormones. Detoxifies poisons and store calcium ions...
