metabolic pathways Flashcards
1
Q
metabolism
A
the sun total of all chemical reactions occurring within a cell
2
Q
metabolic pathways
A
a series of chemical reactions that follow on in stages
- are integrated and controlled pathways of enzyme-catalysed reactions
- irreversible or reversible
- involves anabolism and catabolism
3
Q
anabolic
A
build up large molecules from many smaller molecules and require energy
4
Q
catabolic
A
breaks down large molecules into smaller ones and releases energy
5
Q
ATP in reactions
A
- plays apart in transferring energy from catabolic to anabolic reactions
- reaction 1 is catabolic and energy is released
- reaction 2 is anabolic and energy is requires
6
Q
induced fit
A
- active site has an open position
- high affinity for the substrate
- substrate binds forming enzyme substrate complex
- products alters shape of active site
- product leave the active site allowing another substrate molc to bind
