The Effect Of Temperature On Enzymes Flashcards
What is the Q10 and how is it measured?
It is the temperature coefficient ROR at (T+10)C* / ROR of T C*
What three thing increase when you increase the heat surrounding enzymes?
Kinetic energy
Rate of collisions between substrate and enzyme
The force with which they collide due to increase in KE
What is an enzymes optimum temperature?
When it’s rate of reaction is at maximum
Both the substrate and the enzyme gain kinetic energy what does this mean?
Increase in enzyme substrate complexes
Increase in enzyme product complexes per second
Which bonds break due to kinetic energy and why are they important?
Hydrogen and ionic bonds (the weaker bonds)
They hold the tertiary structure of the enzyme and therefore affect the shape of the active site
Why is it bad that the active site changes?
The substrate will no longer be able to fit
What is the word that describes when an enzyme has permanently and irreversibly changed shape?
It’s has denatured
Which environment do psychrophillic bacteria like?
Cold
