Flashcards in Bio cell unit 2 Deck (29):
0

increase surface area

increase volume
then ratio of SA/V goes down

1

SA
V

amt. supporting cell
higher on small cells

2

surface area

cell membrane

3

volume

cytoplasm

4

prokaryotic

cell membrane
DNA (circular)
ribosomes
3.7 billion
-cell wall (peptidglycogen)
-capsule (carbohydrate) help adhere
-flagela (protein) movement
-pilli (protein) adhere

5

asexxual

binary fission

6

virus

send their DNA in to cell, tell ribosomes to make enzymes that destroy host DNA

7

Eukaryotic

1.5 billion

8

ribosome

builds protein, made of rRNA, reads instruction on mRNA to make protein

9

protein needs to be exported

ribosomes pushes enzymes into ER through pores, enzymes foes to a corner in ER end exits through vesicles (budding).
goes into golgi, exits with destination tag, leves cell (exocytosis

10

golgi

have enzymes
modify
activate
destinates (ships it to final destination

11

motor protein

grabs holds of vesicles and move it to where it needs to go

12

cytotoskeleton

protein fiber, support for cellular shape, provides tracks for motor protein,
microtubules

13

endomembranic system

making protein putting them into membranous structure, then transport them

14

where protein need to go

1. cytoplasm
2. export
3. cell membrane
4. vacuole

15

protein to membrane

exit golgi, inside vesicle with identification marker, enzyme becomes part of vesicle membrane, vesicle membrane becomes part of cell membrane, become channel protein

16

endocytosis

big cell eating smalll cell.
big cell eats bacteria, bacteria covered in a vacuole (cells need to break down into monomers-hydrolysis using enzyme called intra cellular digestion. not needed in humans bc of digestive system.

17

endocytosis contin

lysosomes (have hydrolytic enzymes) digest bacteria

18

endosymbiotic theory

prokaryote eat small prokaryote becomes eukaryote, symbiotic relationship: help eachother

19

invagination

indentation in cell membrane, help maintain SA-V ratio while getting bigger
formation of nucleus

20

funsction of integral protein

transport
ID tag

21

transport
cell membrane

channel protein-specificity. theres always more ___ in ECM bc it gets broken down in cell

22

double membrane

mitochondria and chloroplast

23

diffusion

natural movement, concentrated gradient
-using protein: facilitated diffusion- passive process, no energy

24

neuron

sodium + higher outside, diffusion faciliated when receive message, protein dendrite opens up and continnues down, sodium spreads out, electrical charge gets weaker. equilibrium. close channel. pumps (protein) gets sodium out (active tranport)

25

ID tags

for immune system to know if something belong, glycoprotein complex, diff sugar sequence like DNA

26

diffuse

solutes don't except glucose, O2, CO2

27

Hypertonic

water out, cell shrivel

28

hypotonic

water in, cell swell
