Flashcards in Cell structure Deck (20):
1

Inclusion in cytosol

inert articles - lipids etc.

2

2 main types of organelles

membrane bound and not

3

2 main types of membrane proteins

1. Integral - buried in bylayer
2. Peripheral - not in bylayer, but associate with integral

4

3 main functions of cell membrane

1. Signal transduction - receptor mediated
2. adhesion
3. transfer

5

5 main types of cell transfer

1. Diffusion
2. Active transport
3. Bulk transfer
4. Exocytosis
5. Endocytosis

6

3 types of diffusion

1. Simple - down gradient - fat and uncharged molecules
2. Facilitated - integral protein - no work, but selective
3. Ion channel - voltage or ligand gated

7

Features of active trasport

requires E, against gradient

8

features of bulk transfer

requiires E, conformational changes of membrane

9

3 types of endocytosis

1. pinocytosis - clathrin dep
2. receptor endocytosis - clathrin dep
3. phagocytosis - clathrin INdep

10

3 functions of endocytotis

1. bring stuff in
2. get rid of old membrane
3. reduce amount of membrane

11

Function of endosome

like post office - sorts endocytosed complexes

12

Part of nucleus

Nucleoplasm, DNA, envelope, pores, nucleaolus

13

2 types of chroamitin and function and color

1. Heterochromatin - condensed - dark blue
2. Euchromitin - more easily transcribed - light blue

14

Features of mitochondira

2 membranes
matrix - kreb cycle

15

Features of ribosomes

- non -membrane bound
- site of protein synthesis

16

Features of smooth ER

- no ribosomes
- site of fatty acid, phospholipd, steroid synthesis
- Ca storage

17

Features of rough ER

- has ribosomes
- synthesize non-cytosolic proteins
- create lysosomal enzymes

18

Feat of gogli

- pita bread
- completes glycosylation of proteins
- transports and distributes proteins

19

Feat of lysosomes

- resistant membranes
- contain hydrolytic enzymes

20

3 types of cytoskeleton

1. microfilaments - support cell membrane - actin
2. intermediate filaments - cell support - proteins
3. microtubules - cilia and flagella - tubulin protein dimers
