Question

Enzymes increase the rate of biochemical reaction through
(a)Changing equilibrium
(b)Lowering activation energy
(c)Forming reactant-product complex
(d)Forming enzyme-product complex

Answer 1

Hint: Enzyme is a compound that expands the pace of a substance response without itself being changed by the response.Without an impetus, the measure of energy needed for the response is huge.Compounds and impetuses both influence the pace of a response.The lower the initiation energy for a response, the quicker the pace of synthetic response.

Complete answer:
Let’s discuss the question and find out the correct answer
-Enzymes do not change the equilibrium condition of a biochemical response. ΔG0 and Keq continue as before. Rather, the catalyst decreases the enactment energy required for the response to continue, and consequently expands the pace of response.

- A enzyme reduces activation energy and expands the response pace of a biochemical response. Initiation energy is the energy needed for a response to happen and decides its response rate. Impetuses are substances that expand the response rate by bringing down the enactment energy required for the response to occur.

Hence, the option (b)Lowering activation energy is the correct answer.

Additional Information:
 - Enzymes increment response rates by diminishing the measure of energy needed to shape a complex of reactants that is skillful to deliver response items. This complex is known as the enacted state or progress state complex for the response. Chemicals and different impetuses quicken responses by bringing down the energy of the progress state.

Note: Enzymes that catalyze biochemical response during digestion however itself stay unaffected during the cycle of catalysis. Proteins quicken the pace of biochemical response by diminishing the energy of initiation. Practically all the catalysts are protein in nature aside from ribozymes.
