1

Fluid mosaic model

Used to describe structure of cell membrane

2

Pinocytosis

Form of endocytosis
Smaller substances are brought into the cell by forming vesicles at the cell membrane

3

Facilitated transport

Via proteins requires no energy input

4

Thyroid gland

Requires the active transport of iodine out of blood and into cells

5

Selectively permeable

A membrane that lets some things pass and not pass through

6

Exocytosis

Movement of a vacuole out of the cell

7

Solution

Homogenous mixture where one substance is dissolved into another

8

Phagocytosis

Type of endocytosis
Larger substances are brought into cell by forming vacuoles at cell membrane

9

Receptor- Mediated endocytosis

Occurs when a substance binds to a receptor protein and causes another substance to be taken into the cell via vesicle formation

10

Plasmolysis

Will occur if plant cell is placed in hypertonic solution

11

Crenation

Will occur if animal cell is placed in hypertonic solution

12

Lysis

Occur if animal cell is placed in hypotonic solution

13

Nerve

Kind of cells with large numbers of sodium/potassium pumps

14

Specific

Carrier proteins
Only carry 1 type of particle

15

Hypotonic

Refers to a solution that is less concentrated when compared to another solution

16

Solvent

The substance that does the dissolving in a solution

17

Smaller sized molecules

Tend to produce a higher rate of diffusion

18

Enzymatic proteins

Catalyze chemical reactions on cell membrane

19

Receptor proteins

Cause change to cell membrane when a specifically shaped molecule binds it’s binding site

20

Temperature

Raise temperature = increased diffusion rate (faster molecules)
