Question

TRANSITION STATE OR ENZYME ACTIVE IS MORE EFFECTIVE IN CONVERTING SUBSTRATE INTO PRODUCT ??

Answer 1

Dear student,

Transition state is the state formed during a chemical reaction when enzyme converts reactant into products. It is the state mid way between the reactant and product. It is the unstable state and highly energetic state. Enzyme stabilises the transition state and makes the reaction faster. The energy of the transition state or activation energy is lowered by enzyme and it converts the substrate into product. Enzyme has the ability to modify its active site so that it is better fitted for transition state rather than substrate. So, that when substrate binds, enzyme could easily break the bonds and lower the activation energy. Since enzyme recognises the transition state better and breaks the bonds of the substrate therefore it is effective in converting substrate into product faster by decreasing the activation energy of the transition state and bringing the energy level of the product below the energy level of the substrate.
