NEETChemistryBiomolecules
Activation energy for the acid catalyzed hydrolysis of sucrose is 6.22 kJ mol –1 , while the activation energy is only 2.15 kJ mol –1 when hydrolysis is catalyzed by the enzyme sucrase. Explain.
Options
- AEnzymes increase the temperature, reducing the activation energy required for reactions.
- BEnzymes increase the concentration of reactants, lowering the activation energy barrier.
- CEnzymes, the biocatalysts, reduce the magnitude of activation energy by providing an alternative path. In the
- DEnzymes reduce the pressure in the reaction, affecting the activation energy.
Correct answer
C. Enzymes, the biocatalysts, reduce the magnitude of activation energy by providing an alternative path. In the
Step-by-step solution
Correct Option is : (C) Enzymes, the biocatalysts, reduce the magnitude of activation energy by providing an alternative path. In the hydrolysis of sucrose the enzyme sucrase reduces the activation energy from 6.22 kJ mol –1 to 2.15 kJ mol –1 .
