Enzymes Flashcards
1
Q
Enzymes are
A
Biological catalysts that speed up rate of reaction in cells
2
Q
What are the molecules that fit into the enzymes called?
A
substrates.
3
Q
the active site is the site that?
A
active site is the site that the substrate binds to.
4
Q
Each enzyme will have a unique shape and will only fit one substrate. What is it called?
A
Complementary.
5
Q
When substrate binds to an active site what is it called?
A
enzyme-substrate - complex
6
Q
Summaries the claims between the two models.
Locke-and-key & induced fit model.
A
The lock-and-key model claims that the substrate must exactly fit the active site,
However the induced fit model states the enzyme is more flexible and only becomes complementary after the substrate is bound.
