To investigate the relationship between enzyme activity and substrate concentration, a student is supposed to prepare a reaction
nikdorinn [45]
As i know for finding the speed of an enzyme to do it's work this formula is used
v=v max *[s]/k m +[s]
km shows the amount of substrate we need to make the enzyme work with half of it's max speed and [s] shows the <span>substrate.
we can say that 0.025/0.25=0.1 so the speed is about 0.1 of we wanted to </span>
investigate at the beginning  (we don't consider [s] in the <span>Denominator to solve it easier)
