Answer 2

Given:

Temperature change - 60 degrees to 20 degrees

Temperature coefficient $=4$

To Find: Rate of enzymatic reaction

Solution:

The rate of enzymatic reaction will decrease 4 times for every 10 degrees decrease in temperature.

Therefore,

$\[Rat{e_2} = \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4}(Rat{e_1})\]$

$\[Rat{e_2} = \frac{1}{{64}}\,(Rat{e_1})\]$

Hence, the rate of the enzymatic reaction will become $\[{\frac{1}{{64}}^{th}}\]$ times.
