Question 1

Cholesterol

Answer 1

Keeps the membrane supple to prevent it breaking

Question 2

Glycolipids

Answer 2

On the outer surface of the cell membrane and have a carbohydrate (sugar chain) attached to them

Question 3

Structural proteins

Answer 3

Support the cells and give it strength

Question 4

Receptor proteins

Answer 4

Detect hormones and neurotransmitters

Question 5

Carrier or transport proteins

Answer 5

Allow certain molecules to pass through the cell membrane

Question 6

Active transport

Answer 6

The movement of molecules across the cellular membrane through a protein carrier. Uses ATP

Question 7

Passive transport

Answer 7

The movement of molecules across the cellular membrane via diffusion. Doesn’t use ATP

Question 8

Diffusion

Answer 8

Movement of molecules across the membrane from a high concentration to a low concentration

Question 9

Faciliated diffusion

Answer 9

Uses carrier proteins to move large and charged particles across a cell membrane from a high concentration to a low concentration

Question 10

Endocytosis

Answer 10

Substances form a vesicle and push into the plasma membrane and then release their contents

Question 11

Exocytosis

Answer 11

Substances held in a vesicle push their way out of the plasma membrane and then release their contents

Question 12

Pinocytosis

Answer 12

If the substances moving into a cell is a liquid

Question 13

Phagocytosis

Answer 13

If the substance moving into the body is a solid
