Hvad er de tre produkter fra krebs cyklus?
Citric acid cycle
Citronsyrecyklus (CAC) - også kendt som tricarboxylsyrecyklus (TCA) eller Krebs-cyklus - er en række kemiske reaktioner, der anvendes af alle aerobe organismer til at frigøre lagret energi gennem oxidation af acetyl-CoA fra kulhydrater, fedtstoffer og proteiner til kuldioxid og kemisk energi i form af adenosintrifosfat (ATP).  Desuden leverer cyklussen forløbere for visse aminosyrer samt det reducerende stof NADH, som anvendes i mange andre biokemiske reaktioner.  Dens centrale betydning for mange biokemiske processer tyder på, at den var en af de tidligst etablerede komponenter i det cellulære stofskifte og kan være opstået abiogent. Selv om det betegnes som en "cyklus", er det ikke nødvendigt, at metabolitterne kun følger én bestemt rute; der er anerkendt mindst tre segmenter af citronsyrecyklusen.
Citric acid cycle
The citric acid cycle (CAC) – also known as the tricarboxylic acid (TCA) cycle or the Krebs cycle – is a series of chemical reactions used by all aerobic organisms to release stored  energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP).  In addition, the cycle provides precursors of certain amino acids, as well as the reducing agent NADH, that are used in numerous other biochemical reactions.  Its central importance to many biochemical pathways suggests that it was one of the earliest established components of cellular metabolism and may have originated abiogenically. Even though it is branded as a 'cycle', it is not necessary for metabolites to follow only one specific route; at least three segments of the citric acid cycle have been recognized.
