Flashcards in Chapter 5 Deck (26):
1

Glycolipids/Glycoproteins

Phospholipids and proteins that have attached carbohydrate chains

2

Channel proteins

Passing molecules through the membrane

3

Carrier proteins

Gives a "helping hand" to channel proteins. Also changes shape

4

Cell recognition proteins

Glycoproteins, acts like a "bar code" that helps detect foreign particles

5

Receptor proteins

Shape allows specific molecule to bind to it

6

Enzymatic proteins

Cause specific reactions

7

Junction proteins

Interacting cells

8

Plasma membrane is...

Selectively permeable

9

Passive transport

No energy required

10

Active transport

Energy required

11

Bulk transport

A way that large particles can exit or enter. Exocytosis and endocytosis

12

Diffusion

Higher to lower concentration

13

Equilibrium

When net movement stops

14

Osmosis

Diffusion of WATER across semi permeable membrane

15

Solution

Contains a solute and a solvent

16

Isotonic

Concentration of solute are equal inside and outside of the cell

17

Hypotonic

Turgor pressure, swelling. Solution has less solute than the cell.

18

Hypertonic

Cell shrivels. Solution has more solute than the cell

19

Facilitated transport

Movement of molecules that can't pass directly through membrane

20

Active transport

Energy is required. Molecules move against concentration.

21

Exocytosis

Secretion

22

Endocytosis

Cell takes in substances by forming vesicles around them.

23

Phagocytosis

Intake of large material. Digestion occurs if vehicle fuses with lysosome.

24

Pinocytosis

Occurs when vesicles form around a liquid or around very small particles.

25

Receptor mediated Endocytosis

Molecule coming into cell that binds to specific receptor

26

Extra cellular matrix (ECM)

Meshwork of proteins and polysaccharides found outside of cells
