Question

what does the difference between a and b in this graph indicate? graph: free energy (g) vs progress of reaction, with energy of reactants, energy of products, change in free energy (δg), and two curves (a and b for activation energy?) options: neither letter represents anything that has to do with enzymes; a represents a reaction carried out at room temperature, b represents a reaction carried out in 0 degrees celsius conditions; a is the reaction without an enzyme, b is the reaction with an enzyme; b is the reaction with no enzyme present and a is the reaction with an enzyme present.

Explanation:

Enzymes are biological catalysts that lower the activation energy of a reaction. In the graph, the difference between A and B represents the activation energy. A higher activation energy (A) means the reaction occurs without an enzyme, while a lower activation energy (B) indicates the reaction occurs with an enzyme.

Answer:

A is the reaction without an enzyme, B is the reaction with an enzyme.
