The correct answer is (a) Starch
Explanation: Trypsin is an enzyme that catalyzes reactions involving peptides releasing 10-30 kJ/mol of heat. In the same way, Amylase is an enzyme which catalyzes starch and heat output produced is 8 kJ/mol. Sucrose, urea and uric acid are catalyzed by invertase, urease and uricase. The reactions involving invertase, urease and uricase produces 20kJ/mol, 61kJ/mol and 49kJ/mol amount heat is produced respectively.
