The percentage chance that the child will have blue eyes is: 25%.
Explanation:
According to Mendel laws, there would be a 50% chance of having a child that is heterozygous for the gene (Bb) but happens to express brown eyes because this is the dominant allele; there's 25% chance of having a child who is homozygous for the dominant allele (BB) and will also have brown eyes; finally, there's a 25% chance of having a child who is homozygous for the recessive allele (bb) so their phenotype will be blue eyes.
They change conformation/shape when the right molecule bind in their active site.
They enable reactions to proceed ‘downhill’. For enzyme, when the reactants are more than the products, the reaction proceeds to the right of the reaction. Career proteins also carry molecules down their concentration gradient.
Both career proteins and enzymes are not denatured during the process of their biological activity
