Transcript of KEMIJA V ŽIVIH SISTEMIH

ADRENALIN HEMOGLOBIN Ca, P soli celuloza škrob glukoza v mitohondriju klorofil v kloroplastih DNK v jedru Iz katerih kemijskih spojin in elementov je zgrajen vsak organizem? Ogljik ima glavno vlogo v vseh živih organizmih, saj ima sposobnost tvorjenja mnogih spojin, ki gradijo vsa živa bitja. Poleg OGLJIKA, so vsi živi organizmi zgrajeni še iz vodika, dušika, kisika, fosforja, kalcija in žvepla. Vsi organizmi vsebujejo majhne molekule (voda, soli) in velike molekule
(ogljikov hidrati, maščobe, beljakovine, DNK molekule) beljakovine maščobe OGLJIKOV HIDRAT OGLJIKOV HIDRAT glavni vir energije za žive organizme:
CELIČNO DIHANJE rezerva energije
gradijo celične membrane omogočajo prenos kisika
gradijo dele telesa
izgradnja hormonov
boj proti bakterijam ureja kemijske dejavnosti v telesu
shranjuje informacije
določa lastnosti telesa celične membrane
