Enzyme saturation is a phenomenon that two of the answers are correct. leads to a decrease in the rate of that reaction. occurs when reactant concentration exceeds the number of enzymes. can never be compensated for by the body. occurs when an equilibrium exists between the creation of new products and creation of new reactants.

Leads to a decrease in the rate of that reaction.

Occurs when reactant concentration exceeds the number of enzymes.

Explanation:

Enzymes are specific this means they will only act over the substrate they were meant for. If the number of enzymes is higher, the reaction rate will decrease because there is not enough materials (substrate) to be reacting with. Its like a factory if your have 10 employees but you are only getting 1 car to be making your production slows down because you do not have enough materials to be working with

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )
