1 Outside of cell Inside of cell (cytoplasm) Cell membrane Proteins Protein channel Double Fat Layer Carbohydrate chains Parts of the Cell Membrane Go to Section:

2 Homeostasis Maintenance of a stable internal condition Balance

3 Vocab Vesicle: –Membrane-covered compartments that forms when part of the cell membrane surrounds an object and pinches off

4 Diffusion

5 Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen

6 Diffusion Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen High Low

7 Diffusion Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen High Low

8 Diffusion Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen High Low NO Requires NO ATP (energy), moves only small particles

9 Diffusion Definition: Movement of small particles from an area of high concentration to an area of low concentration, like oxygen High Low NO Requires NO ATP (energy), moves only small particles Osmosis: the diffusion of water

11 Passive Transport

12 Definition: the movement of medium particles from an area of high concentration to an area of low concentration through a protein channel

13 Passive Transport NO Requires NO ATP (ENERGY) Definition: the movement of small & large particles from an area of high concentration to an area of low concentration through a protein channel

14 Passive Transport NO Requires NO ATP (ENERGY) Definition: the movement of medium particles from an area of high concentration to an area of low concentration through a protein channel Just like diffusion but through a protein

15 Passive Transport Definition: the movement of med. particles from an area of high concentration to an area of low concentration Requires NO ATP (ENERGY) Just like diffusion but through a protein Low High

16 Passive Transport Definition: the movement of med. particles from an area of high concentration to an area of low concentration Requires NO ATP (ENERGY) Just like diffusion but through a protein Low High

17

18 Active Transport

19 Definition: the movement of medium particles from an area of low concentration to an area of high concentration through a protein channel

20 Active Transport Definition: the movement of med. particles from an area of low concentration to an area of high concentration through protein channel Requires ATP (ENERGY)

21 Active Transport Definition: the movement of med. particles from an area of low concentration to an area of high concentration through a protein channel Requires ATP (ENERGY) Similar to Passive Transport but requires energy

22 Active Transport Definition: the movement of med. particles from an area of low concentration to an area of high concentration Requires ATP (ENERGY) Low High Similar to Passive Transport but requires energy

23 Active Transport Definition: the movement of sm. & lg. particles from an area of low concentration to an area of high concentration Requires ATP (ENERGY) Low High Energy Similar to Passive Transport but requires energy

25 ENDOCYTOSIS

26 Definition: the cell taking in particles by surrounding the particle and enclosing it in a vesicle

27 ENDOCYTOSIS Definition: the cell taking in particles by surrounding the particle and enclosing it in a vesicle Step 1: the cell comes into contact with a particle

28 ENDOCYTOSIS Definition: the cell taking in particles by surrounding the particle and enclosing it in a vesicle Step 1: the cell comes into contact with a particle

29 ENDOCYTOSIS Definition: the cell taking in particles by surrounding the particle and enclosing it in a vesicle Step 1: the cell comes into contact with a particle Step 2: the cell membrane begins to wrap around the particle

30 ENDOCYTOSIS Definition: the cell taking in particles by surrounding the particle and enclosing it in a vesicle Step 1: the cell comes into contact with a particle Step 2: the cell membrane begins to wrap around the particle

31 ENDOCYTOSIS Definition: the cell taking in particles by surrounding the particle and enclosing it in a vesicle Step 1: the cell comes into contact with a particle Step 2: the cell membrane begins to wrap around the particle Step 3: once the particle is completely surrounded, a vesicle pinches off

32 ENDOCYTOSIS Definition: the cell taking in particles by surrounding the particle and enclosing it in a vesicle Step 1: the cell comes into contact with a particle Step 2: the cell membrane begins to wrap around the particle Step 3: once the particle is completely surrounded, a vesicle pinches off

33 Endocytosis

35 EXOCYTOSIS

36 Definition: Vesicles formed by the Golgi carry particles to the cell membrane to be removed

37 EXOCYTOSIS Definition: Vesicles formed by the Golgi or ER carry particles to the cell membrane to be removed Step 1: large particles that must leave the cell are packaged in vesicles

38 EXOCYTOSIS Definition: Vesicles formed by the Golgi or ER carry particles to the cell membrane to be removed Step 1: large particles that must leave the cell are packaged in vesicles

39 EXOCYTOSIS Definition: Vesicles formed by the Golgi or ER carry particles to the cell membrane to be removed Step 1: large particles that must leave the cell are packaged in vesicles Step 2: the vesicle travels to the cell membrane and fuses with it

40 EXOCYTOSIS Definition: Vesicles formed by the Golgi or ER carry particles to the cell membrane to be removed Step 1: large particles that must leave the cell are packaged in vesicles Step 2: the vesicle travels to the cell membrane and fuses with it

41 EXOCYTOSIS Definition: Vesicles formed by the Golgi or ER carry particles to the cell membrane to be removed Step 1: large particles that must leave the cell are packaged in vesicles Step 2: the vesicle travels to the cell membrane and fuses with it Step 3: the cell release the particles into its environment

42 EXOCYTOSIS Definition: Vesicles formed by the Golgi or ER carry particles to the cell membrane to be removed Step 1: large particles that must leave the cell are packaged in vesicles Step 2: the vesicle travels to the cell membrane and fuses with it Step 3: the cell release the particles into its environment
