Flashcards in B1.2.4 Enzyme reactions Deck (12):
What factors effect the rate of an enzyme-catalysed reaction?
Concentration of enzymes and substrate
State the correct term for the conditions which an enzyme work best in
The optimum conditions
Generally, what happens to the rate of an reaction in a higher temperature?
The higher the temperature the faster the reaction
What happens to the rate of collisions between enzymes and substrate in a higher temprature
The rate of collisions increase
What happens to an enzyme if the temperature is too high?
The amino acid chains in the protein start to unravel, changing the shape of the active site
State the correct term that describes an enzyme which active site has been changes shape
What happens to the rate of reaction when the temperature gets to high?
Describe what happens when an enzyme denatures
The substrate can no longer bind to the enzyme and so the rate of reaction decreases
How does a change in pH effect an enzyme?
A change in pH effects the interactions between amino acids, this may make the enzyme unfold, changing the shape of the active site
Generally, what happens to the rate of an reaction in a higher substrate concentration?
Generally, what happens to the rate of an reaction in a higher enzyme concentration?
