The Unit Of Enzyme Activity Flashcards
1
Q
It is recommended that the unit in which enzyme activity is expressed be
A
The amount of activity that converts one mole of substance per second and is called the katal (symbol Kat )
2
Q
It is found that activities are more conveniently expressed in
A
Microkatals (ukat)
I e 10 -6 K atlas
3
Q
The standard calibration curve has been constructed using amounts of p-nitrophenol expressed in U moles in a total volume of
A
11.1 ml
4
Q
In order to convert the product concentration into an enzyme activity, it is necessary to divide
A
The U moles p-nitro formed by the number of seconds incubation time ie U Moles product formed/ incubation time in seconds = enzyme activity in U Kat
