Question
The following question is based on the reaction A +BC + D shown in the figure. C. b. A+B e. a. d. C+D Progress of the Reaction Which best describes the reaction? The amount of free energy present in the products is indicated by "e." O The amount of free energy released as a result of the noncatalyzed reaction is indicated by "c." O The amount of free energy initially present in the reactants is indicated by "a." O The difference between "b" and "c" is the activation energy added by the presence of the enzyme. O The amo energy released as a result of the catalyzed reaction is indicated by"d Submit Request AnswerExplanation / Answer
Answer: In the given graph we need infer what best describes the reaction A+B--->C+D. This will be the forward reaction i.e. reactant A and B are getting converted to product C+D.
First, let us understand the data points in the graph. Now, the graph is free energy vs progress of the reaction.
Let's see the data points in the graph one by one.
1. "a". in the graph represents activation energy required when the reaction goes in the enzyme-catalyzed
reverse direction i.e. from C+D-->A+B. Activation energy is nothing but the energy required for the reaction to happen. As we know enzyme-catalyzed reaction shows lower the activation energy as compared to uncatalyzed reaction.
2. "e". in the graph will be activation energy required when the uncatalyzed reaction goes in the reverse direction i.e. C+D--->A+B
3. "b". in the graph is the activation energy in case of reaction that is catalyzed by an enzyme
4. "c". is the activation energy in case of reaction that is uncatalyzed hence it shows higher curve than "b" which is catalyzed
5. "d" is the difference between the free energy of content and the product. It will be the amount of energy released when the product is formed from reactant in the given reaction and it will be represented by delta G which will have negative value since the free energy of product is less than the free energy of reactant and so the reaction will be exerogenic. So the correct the option will be option.e. i.e. "free energy released as a result of the catalyzed reaction indicated by d".
