Q

co sa este nachadza na povrchu BS p.buniek?

A

puzdro
bičík, brvy

17
Q

na co sluzi puzdro na povrchu BS

A

zvysuje odolnost bunky

18
Q

Bicik a brvy

A

zapezpecuju pohyb su bielkovinoveho charakteru

19
Q

vyskyt cytoplazmatickej membrany

A

nachadza sa pod bunkovou stenou
je sucastou bunkovych povrchov

20
Q

chemicke zlozenie CM 3

A

fosfolipidiva dvojvrstva
bielkoviny - integralne a periferne
Glykoproteínové vlákna

21
Q

cim prechadzaju integrálne bielkoviny a co dodavaju

A

prechadzaju dvojvrstvou a dodavaju pevnost

22
Q

periferne bielkoviny

A

ponorene prevazne enzymy

23
Q

aku funkciu ma CM

A

reguluje prijem a vydaj látok do bunky z a bunky
METABOLICKÁ funkcia -obsahuje ENZÝMY ktore sa podielaju na synteze ATP

24
Q

aku priepustnost ma CM

A

semipermeabilna -polopriepustna

25
Q

co to znamena semipermeabilna

A

NEprepusta ale REGULUJE latky potrebne pre zivot

26
Q

aky charakter maju glykoproteínove vlakna

A

bielkovinovo sacharidovy charakter

27
Q

vyskyt cytoplazmy alebo co to je

A

zakladna hmota ktora vyplna vnutorny priestor bunky

28
Q

aky roztok je cytopkazma

A

viskozny nie je tuha ani riedka

29
Q

ake chemicke zlozenie ma cytoplazma

A

viskozny roztok s anorganickymi aj organickymi latkami

30
Q

aku funkciu ma cytoplazma

A

-tvori prostredie pre bunkove organely
-prebieha tu premena latok , vymena energie a latok
-cim je redsia tym lahsie ide premena

31
Q

kde sa vyskytuje nukleoid

A

volne ulozemy v cytoplazme neohraniceny biomembranou
nema staky tvar

32
Q

nukleoid stavba

A

1 do kruhu uzavreta molekula DNA
prokaryoticky chromozom

33
Q

co je to prokaryoticky chromozom

A

jedna molekula ktora tvori nukleoid

34
Q

aku funkciu ma nukleoid

A

nositel gemetickych inf pre prezitie bunky
riadenie vswtkych funkcii v bunke
