The Effect of Temperature on Enzyme Controlled Reactions

https://www.youtube.com/watch?v=mvRtFCeWOZo

Why does rate of enzyme controlled reactions increase as temp increases

Kinetic energy increases of both enzyme and substrate, as they move more rapidly, there will be more frequent successful collisions with active site, causing rate of reaction to increase

Whats optimum temp

Max number of collisions between substrate and active site, for humans it is around 40 degrees.

What happens if temp reaches past optimum

As temp increases past the optimum , rate of reaction decreases, this is because at higher temps, enzyme molecule vibrates more rapidly, causes bonds within enzyme to break, and so tertiary structure of enzyme molecules changes.

As shape of active site changes, its no longer complementary to substrate, and so enszyme denatured and doesnt function

Whats the temperature coefficient (Q10)

Temp coefficient (Q10) = Rate of reaction at temp X + 10 degrees / Rate of reaction at temp X
