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?

Duchenne muscular dystrophy is a serious condition caused by a recessive allele of a gene on the human x chromosome. the patients have muscles that weaken over time because they have absent or decreased dystrophin, a muscle protein. they rarely live past their twenties. how likely is it for a woman to have this condition? a) women can never have this condition.b) one-fourth of the daughters of an affected man would have this condition.c) one-half of the daughters of an affected father and a carrier mother could have this condition.d) only if a woman is xxx could she have this condition.
