Question
Chapter 23, Problem 23.7P
Interpretation Introduction
Interpretation:
Difference in reactions catalyzed by lyases and hydrolases is to be determined.
Concept introduction:
The chemical digestion of food is done by the digestive enzymes. All of the digestive enzymes that break down the food molecules in the presence of water are hydrolases. Lyases enzymes are responsible for catalyzing the addition of groups to double bond or removal of groups to form double bonds.

The best explanation is: As the reactant concentration increases, the rate constant increases. the activation energy increases. the frequency of molecular collisions increases. the order of reaction increases. the average kinetic energy of molecules increases.arrow_forwardGlycolysis is the process by which glucose is metabolized to lactic acid according to the equation C6H12O6(aq)2C3H6O3(aq) G=198 kJ at pH 7.0 and 25°C Glycolysis is the source of energy in human red blood cells. In these cells, the concentration of glucose is 5.0103 M, while that of lactic acid is 2.9103 M. Calculate AG for glycolysis in human blood cells under these conditions. Use the equation G=G+RT In Q, where Q is the concentration quotient, analogous to K.arrow_forward
