Enzyme Controlled Reactions Flashcards
(10 cards)
1
Q
What do enzymes do?
A
Catalyze biochemical reactions in cells.
2
Q
Define ‘enzyme-substrate complex.’
A
Temporary enzyme-substrate bonding.
3
Q
How do enzymes lower activation energy?
A
Provide alternative reaction pathway.
4
Q
Explain enzyme specificity.
A
Specific to particular substrate molecules.
5
Q
What is the role of cofactors?
A
Assist enzyme function or structure.
6
Q
Describe ‘induced fit model.’
A
Substrate induces enzyme shape change.
7
Q
What is an allosteric site?
A
Site on enzyme other than active site.
8
Q
Define ‘competitive inhibition.’
A
Competes with substrate for binding.
9
Q
How does temperature affect enzyme activity?
A
Increases activity, then denaturation.
10
Q
What is the function of inhibitors?
A
Slow or stop enzyme activity.
