Hydrolysis reactions (sugars, proteins, nucleic acids, fats) in general are considered first order reactions despite that each of these molecules react with a molecule water. For example sucrose + H2O →→ fructose + glucose Why? Select one: a. Water is in excess and the concentration does not change on time, so the constant concentration value is incorporated into the rate constant b. Only occur in the presence of enzymes c. It is not known d. hydrolysis reactions are not reversible
