[{'content': 'Force not acting in an enzyme substrate complex : \nSelect and explain. \nA. Electrostatic, B. Covalent, C. Van der waals, D. Hydrogen', 'role': 'user'}, {'content': "Answer: C \nExplanation: Vander Walls' forces are too weak, to actively paicipate in formation of enzyme- substrate complex. Forces contribute in binding are:- Hydrogen bondingQ- Ionic (electrostatic) bonding- Hydrophobic interactionEnzymes function to decrease the activation energy so that reactions can occur at normal body temperature. The substrate form a covalent bond with the enzymes active site, & accelerates the reaction.", 'role': 'assistant'}]
