T1 - 3.1.4.2 enzymes Flashcards
1
Q
what is the structure of enzymes
A
- globular proteins
- a few have tertiary structure (trypsin)
- most have quaternary structure
2
Q
what is a catabolic reaction
A
BREAK into smaller molecules
3
Q
what is an anabolic reaction
A
smaller ones MADE into larger molecules
4
Q
what is the induced fit model stages
A
5
Q
what is the process of induced fit
A
- substrate binds to the active site causing the tertiary structure to change (conformational change)
- this change pulls apart an atom, changing the bond angles and lowering the energy needed to break it
- therefore the substrate in the product breaks down and the enzyme reverts to its original state
6
Q
what is the equation for rate of reaction
A
change/time
7
Q
stage 1 of induced fit model
A
substrate binds to the active site causing the tertiary structure to change (conformational change)
8
Q
stage 2 of the induced fit model
A
this change pulls apart an atom, changing the bond angles and lowering the energy needed to break it
9
Q
stage 3 of the induced fit model
A
- therefore the substrate in the product breaks down and the enzyme reverts to its original state
