- aerobni in anaerobni organizmi (potrebujejo in ne potrebujejo kisika)
- avtotrofni in heterotrofni organizmi

Q

katabolizem

A
  • snovi se razgrajujejo energija se sprošča
    npr. celično dihanje
    C12 H12 O6 6O2 - > 6CO2 + 6H20
    alkoholno vrenje (v citoplazmi)
    C6 H12 O6 -> 2C2 H5 OH + 2CO2 (+2ATP), (anaerobni proces)

Q

anabolizem

A
  • snovi se sintetizirajo, energija se porablja
    npr. fotosinteza
    6H2 O + 6CO2 -> 6O2 + C6 H12 O6
