Topic 6(level C) Flashcards
Anabolic pathways involve?
Anabolic pathways invoke biosynthetic processes
Catabolic pathways release ?
Energy
Catabolic pathways involve ?
The breakdown of molecules
What pathway releases energy ?
Catabolic pathways
What pathway requires energy ?
Anabolic pathways
These pathways can have what ?
These pathways can have reversible and irreversible steps and alternative routes
What’s the control of metabolic pathways ?
The presence or absence of particular enzymes and the regulation of the rate of reaction of key enzymes within the pathway
Regulation can be controlled by what ?
Regulation can be controlled by intra and extra cellular signal molecules
Enzymes often act in ?
Enzymes often act in groups or as multi enzyme complexes
Control of metabolic pathways through ?
Competitive , non-competitive and feedback inhibition
What does the competitive inhibitor do ?
Binds to active site
What does the non competitive inhibitor do ?
Changes shape of active site
What does feedback inhibition do ?
End product binds to an enzyme that catalyses a reaction early in the pathway
Anabolic pathways require ?
Anabolic pathways require energy
