Temperature:
- more heat means more kinetic energy, so molecules move faster.
- making the substrate molecules more likely to collide with the enzyme's active site.
- the energy of these collisions also increases which means they are more likely to result in a reaction.
- the rate continues gto reach up until the optimum temperature- where the rate of the enzyme controlled reaction is at its fastest.
- if the temperature gets too high the molecules vibrate more and this vibration can break bonds that hold the enzyme in its shape.
- the active site changes shape and the enzyme and substrate no longer fit together. and its denatured.
The temperature Coefficient (Q10):
- shows how much the rate of reaction changes when the temperature is raised by 10^C.
- Q10= R2( rate at higher temp) / R1 (rate…
