Flashcards in Simple Transport Deck (20):
1

Diffusion

Movement of molecules

Simple transport

2

What are the two types of diffusion?

Osmosis

Dialysis

3

Osmosis

Movement of water passed a membrane

4

Dialysis

Movement of solutes (everything else) passed a membrane

5

What are the three types of dialysis?

Simple

Passive

Facillitated

6

Simple dialysis

Movement of molecules along concentration gradient

7

Passive dialysis

Movement of molecules through a membrane along a concentration gradient

8

Facillitated dialysis

Movement of molecules through a membrane by use of a carrier molecule (protein) along concentration gradient

9

Where does passive go through?

Passive dialysis goes through blue balls.
If it can't go through, it's called facillitated

10

Active transport

Movement of solutes across a membrane "against" concentration gradient by use of atp

11

Atp

Only energy source for cell

12

How many types of active transport are there

3

Exocytosis

Endocytosis

Receptor mediated

13

Exocytosis

Movement of large amounts of solutes OUT of the cell whereby the transport molecule becomes part of the plasma membrane after releasing its contents

14

Endocytosis

movement INTO the cell

15

How many types of endocytosis are there?

2

Phagocytosis

Pinocytosis

16

Phagocytosis

Cell eating ; PACMAN

Portion of the cell plasma membrane surrounds incoming substance then fuses with a lysosome (stomach cell)

17

Pinocytosis

Cell drinking ; FLY EATING

Substance is dissolved outside the cell and then enters as i did in phagocytosis

18

Receptor mediated

Incoming substance can only enter if there is a receptor sight within plasma membrane that it bonds to, allowing a transport vesicle to form

Ex HIV

19

What are enzymes made of

Protein

20

Simple transport

Movement of molecules in direction of concentration gradient
