enzymes Flashcards
(10 cards)
What are enzymes?
Biological catalysts regulating biological processes in living organisms.
What does the protein nature and tertiary structure of an enzyme determine?
Its specific function.
What do enzymes do?
They lower the activation energy to increase the rate of reaction.
How do enzymes lower activation energy?
Through the formation of enzyme-substrate complexes.
What does the unique tertiary structure of an enzyme determine?
The shape of its active site
What does the substrate have to be to fit the enzyme’s active site?
Complimentary
What is it called when the enzyme and the substrate have binded together?
Enzyme-substrate complex
What are the two enzyme models?
Lock and key model, induced-fit model
Which model is more accurate?
Induced-fit model
Why are enzymes specific?
To give control over reactions or biochemical pathways
