Samenvatting

In hoofdstuk 5 wordt uitgelegd hoe de eerder in het katabolisme gevormde energierijke elektronenparen van NADH en FADH2 worden gebruikt om ATP te produceren. Deze oxidatieve fosforylering gebeurt in de binnenste mitochondriale membraan via een aantal eiwitcomplexen die de redoxenergie van de elektronenparen omzetten in een elektrochemisch potentiaal van een protonengradiënt. Een belangrijke component van deze complexen zijn cytochromen die hun redoxreacties uitvoeren zonder veel kans op ongewenste reacties, zoals vorming van zuurstofradicalen. Pas de allerlaatste elektronenacceptor is dizuurstof, dat wordt gereduceerd tot water. De nuttige energie van de protonengradiënt wordt vervolgens in complex V (mitochondriaal ATP-synthase) gebruikt voor de reactie ADP + Pi ⇒ ATP. Een geconcerteerd samenspel van de complexen I tem V zorgt voor een flux van oxidatie die afgestemd is op de flux van ATP-synthese (respiratoire koppeling). In de aanwezigheid van UCP’s (‘uncoupling proteins’) ontstaat echter een protonenlek zonder ATP-synthese (respiratoire ontkoppeling).
