Enzymes Flashcards
1
Q
Lock and key theory
A
Enzyme has active site that substrate can bond to
2
Q
Metabolic reaction
A
Anabolic+catabolic reaction
3
Q
Induced fit theory
A
As substrate approaches, active site changes accordingly.
Returns to normal post reaction
4
Q
Activation energy factors
A
Substrate concentration
Enzyme concentration
Temperature
pH
5
Q
Optimum rate
A
When all active sites are in use
6
Q
Less substrates
A
Quicker reaction
7
Q
Optimim temperature
A
30-40 degrees
8
Q
pH effect
A
Directly affects 2ndry and tertiary structure of enzymes
9
Q
Ideal pH
A
Neutral/slightly alkaline
10
Q
Competitive inhibitors
A
Molecules of similar shape substrate but don’t react
11
Q
Non-competitive inhibitors
A
Bind to part of the enzyme
More inhibitory
