Question

An enzyme is known to possess a single active state, but 10 inactive states. The inactive states are all approximately 5.8 kJ/mol higher in energy than the active state i) Over what temperature range does the enzyme spend more than 50% of its time in the active state? ii As the temperature of the system gets very high (approaching infinity for any practical purpose), what is the probability to find the enzyme in its active state? iii) What changes could you try to make to the enzyme to make it perform more efficiently (i.e. stay active a higher percentage of the time) at the temperature calculated in part i?

Explanation / Answer

Each enzyme has a temperature in which it works optimally like for humans 37 degree celcius and some work at too low temperature like animal living in Arctic area.As the temperature increases the activity of enzyme is catalyzed.Also pH affects the activity and inactivity state of enzyme.
