Topic 1.7 - Enzyme action Flashcards
1
Q
What is the initial amount of energy needed called?
A
Activation energy
2
Q
What type of protein is an enzyme?
A
A globular protein
3
Q
What specific region of an enzyme is functional?
A
The active site
4
Q
What is the induced fit model of enzymes?
A
proposes that the active site forms as the enzyme and substrate interact
- the enzyme is flexible and can mould itself around the substrate
5
Q
“The enzyme puts a strain on the substrate molecule” - what does this do?
A
This strain distorts bonds in substrate and lowers activation energy to break the bonds
6
Q
For an enzyme to work it must:
A
- come into physical contact with its substrate
- have an active site which fits the substrate
