Question

What is major structure of the cell membrane and a main source of energy while at rest

Answer 1

Answer:

The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.glucose

In addition to being the main source of energy, glucose is utilized in other pathways, such as glycogen and lipid synthesis by hepatocytes.
