Question
### Free Energy Change for Fructose-6-Phosphate and ATP Reaction #### Graph Explanation The graph illustrates the free energy change for the reaction of Fructose-6-phosphate and ATP forming Fructose-1,6-bisphosphate and ADP. It compares the reactions in the presence (blue line) and absence (red line) of an enzyme. The x-axis represents the progress of the reaction, while the y-axis represents energy. #### Graph Arrows - **Arrow A**: Represents \( \Delta G \) for the reaction, the change in free energy from reactants to products. - **Arrow B**: Represents the energy of activation for the forward reaction in the presence of the enzyme. This is the energy barrier overcome during the reaction, which is lower with an enzyme (blue line). - **Arrow C**: Represents the energy of activation for the forward reaction in the absence of the enzyme (red line). The energy required is higher without the enzyme, illustrating the enzyme's catalytic effect. - **Arrow D**: Represents the energy of activation for the reverse reaction in the absence of the enzyme. #### Key Concepts - **Enzyme Effect**: Enzymes lower the activation energy for reactions, making them proceed more quickly. - **Reaction Progress**: The graph shows the alteration in energy as the reaction proceeds from reactants to products. - **Energetics**: Understanding these concepts is crucial for studying biochemical pathways and reactions in biology and chemistry. This interactive diagram helps illustrate the role of enzymes in biochemical reactions, emphasizing their importance in reducing activation energy barriers.
