The enthalpy for ATP hydrolysis is -24 kJ/mol at 37 C. The entropy for ATP hydrolysis 22 J/molk at 37 C. The free energy for the conversion of glucose to glucose-6-phosphate is 17 kJ/mol at 37 C. What is the total free energy of the coupled reaction of glucose and ATP to form glucose-6-phosphate, ADP, phosphate, and water at 37 C? -31 kJ/mol -7 kJ/mol + 7 kJ/mol -14 kJ/mol +15 kJ/mol -48 kJ/mol The pKa of aspirin is 3.5. The pH is different in different places in the digestive system. In which conditions will the aspirin be protonated? saliva in mouth pH ~6.7 stomach pH ~2 ileum ~7.4 caecum ~5.7 rectum ~6.7 saliva stomach ileum caecum rectum What functional groups are present in acetylsalicylic acid? Select all the correct groups. C-OH -CH3 Acetylsalicylic acid (aspirin) carboxylic acid ketone aldehyde alcohol ester amide = The active ingredient in aspirin is acetylsalicylic acid (HC9H704), a monoprotic acid with Ka = 3.3 x 10-4 at 25 C. What is the pH of a solution obtained by dissolving 2 extra-strength aspirin tablets, each containing 500 mg of acetylsalicylic acid, in 250 mL of water?
