What are the effects of the inhibitor galactose compared to water? How are they related to the substrate? Cite the data.
a. Galactose increases enzyme activity compared to water; it competes with the substrate for binding sites
b. Galactose decreases enzyme activity compared to water; it inhibits substrate binding
c. Water increases enzyme activity compared to galactose; it acts as a cofactor for the substrate
d. Water decreases enzyme activity compared to galactose; it facilitates substrate binding
