Lesson 8- Cell Membrane

Question 1

Function

Answer 1

allows the cell to alter its shape, regulates the movement of materials into and out of a cell. surrounds, protects, and insulates all cells.

Question 2

Structure

Answer 2

phospholipids, proteins, cholesterol, and carbohydrates

Question 3

Phospholipids

Answer 3

primary structure of the cell membrane is a phospholipid bilayer

Question 4

Proteins

Answer 4

membrane transport, hormone receptors, and attaching the membrane to the cytoskeleton (cell to cell communication)

Question 5

Cholesterol

Answer 5

hydrophilic and hydrophobic components. keeps the cell membrane fluid-like and stable, immobilizes the outer surface to make it less soluble for small water-soluble molecules to pass, and separates phospholipids

Question 6

Carbohydrates

Answer 6

cell recognition and cell to cell communicating, olgiosaccharides link to lipid and pr-.
