A biologist wants to increase the rate of his chemical reaction but has a limited amount of enzyme. He continues to increases the substrate concentration instead. Eventually, the reaction rate levels off, and he can't get it to go any faster. What prevented the rate from increasing further?

A)the solution ran out of enzyme
B)the subrate concentration ran out of vmax
c)the products of the enzyme inhibited the reaction
d)the solution ran out of reactants

A biologist wants to increase the rate of his chemical reaction but has a limited amount of enzyme. He continues to increases the substrate concentration instead. Eventually, the reaction rate levels off, and he can't get it to go any faster. What prevented the rate from increasing further? 

A)the solution ran out of enzyme
B)the subrate concentration ran out of vmax
c)the products of the enzyme inhibited the reaction
d)the solution ran out of reactants

A) Because enzyme are the catalysts, enabling reactions with the substrates, and since it said that the biologist only had a limited amount of enzyme, he added extra substrate. Basically, the solution ran out of enzyme to create more reactions and he ended up with left over substrate and no enzyme, because they were all used up.
