Q1. Evaluate the sizes of the different digestive organs of an earthworm. Which organ is the largest? How does its size make it well suited for its function?
Q2. The standard free energy vary for the hydrolysis of ATP is -30.5 kJ/mol. Measurements in rat liver cells indicate that the concentrations for both ATP and ADP are 8 mM and for inorganic phosphate is 1 mM. Calculate the free energy change for this hydrolysis reaction under cellular conditions at 37°C (298°K).
