Lesson Four

Question 1

Fluid mosaic model

Answer 1

Double layer of phospholipids but proteins are scattered through the membrane

Question 2

Glycoprotein

Answer 2

Protein and carbohydrate chain

Question 3

Glycolipid

Answer 3

Phospholipids and carbohydrate chain

Question 4

Diffusion

Answer 4

Movement of solute from an area of high concentration to an area of low until evenly distributed. Needs nothing

Question 5

Osmosis

Answer 5

Diffusion from area of high to low concentration

Question 6

Facilitated transport

Answer 6

Solutes move across membrane from area of high solute to low solute

Question 7

Active transport

Answer 7

Solutes move from an area of low solute to high solute, need membrane, Carrier cell, ATP, and goes against the flow.

Question 8

Factors that affect diffusion:

Answer 8

Surface area vs volume
Amount of cell membrane
The size of cell

Question 9

Endocytosis

Answer 9

Phagocytosis: large pieces

Pinocytosis: smaller larger pieces

Question 10

Exocytosis

Answer 10

Process which products or wastes exit a cell, reverse of endocytosis
