, 3.1 Chemie in cellen
Metabolisme
Stofwisseling (metabolisme) = Chemische omzettingsprocessen in een organisme (mede mogelijk gemaakt
door enzymen).

Stofwisselingsprocessen die in rust doorgaan = Basale metabolisme

(An)organische stoffen
Stoffen zijn in 2 groepen te verdelen:
• Organische stoffen – C én H (en vaak O), binding met veel energie
• Anorganische stoffen – C óf H, binding met weinig energie

Assimilatie & Dissimilatie
Stofwisselingsprocessen zijn in 2 groepen te verdelen:
• Opbouw: Assimilatie
Doel: Vorming van organische stoffen waaruit individu bestaat
Energie: Benodigd
Voorbeeld: Koolstofassimilatie (= fotosynthese), C6H12O6 (glucose) uit CO2 + H2O

• Afbraak: Dissimilatie
Doel: Vorming van organische stoffen waaruit individu bestaat
Energie: Komt vrij
Voorbeeld: Verbranding




Voortgezette assimilatie (par 3.4) = Glucose is grondstof voor vorming van andere koolhydraten, vetten,
eiwitten, DNA.

Autotroof = Zelf energie kunnen maken (planten)
Heterotroof = Energie uit voeding van organismen (dieren, mensen, bacteriën, schimmels)
