Q

presnova

A

/METABOLIZEM
=celota vseh kemijskih reakcij v celici
ožje gledano=intermediarna presnova, ki zajema osnovne poti sinteze (izgradnje) in razgradnje, ki potekajo v večini celic

Q

zakaj ločimo različne metabolne poti?

A

večina substratov se presnavlja preko vmesnih produktov do za organizem uporabnega produkta

Q

kaj se dogaja v katabolnih in anabolnih presnovnih poteh?

A
  • v katabolnih procesih -> se sprošča energija
  • v anabolnih procesih -> se porabljaenergija
