FLASHCARDS: Topic 8.1 - Metabolism

Question	Answer
Metabolic Pathways	a sequence of small steps that form chemical reactions (can be a chain or cycle)
Activation energy	the amount of energy required to reach the transition stage from substrate into product
Competitive inhibitors	interfere with the active site, the enzyme is temporarily occupied
Non-competitive inhibitors	bind at a location other than the active site, they change the shape of the enzyme
Effect of competitive inhibitor	it takes a higher concentration to reach the maximum rate, but it can get there
Effect of non-competitive inhibitor	the enzyme doesn't reach the maximum rate of reaction because some enzymes cannot react (shape change) but it follows the same pattern as a uninhibited enzyme

End-product inhibition	when the end product of the pathway acts as an inhibitor
Allosteric interactions	when enzymes regulated by chemical substances bind to special sites on the enzyme away from the active site
Allosteric sites	where allosteric interactions take place
