Tobin performed an experiment in which he mixed varying amounts of enzyme with an excess amount of substrate. he measured the rate of each reaction and recorded his data in the table below.
enzyme concentration
(millimoles) reaction rate
(micromoles/minute)
0 0
100 0.05
200 0.10
300 0.15
400 0.20
500 0.25
what can tobin conclude about the relationship between the enzyme concentration and the reaction rate in the presence of excess substrate?
