The image presents a cyclic diagram with five enzyme-substrate complexes labeled A, B, C, D, and E. Each complex is indicated by brackets surrounding colored shapes that likely represent substrates or products. The diagram features arrows showing the direction of the reactions taking place in each step.

- **A**: A complex with a blue and red substrate.
- **B**: An empty site awaiting a substrate.
- **C**: A complex with the substrate now transformed with blue and red sections merging.
- **D**: An empty site ready for another cycle.
- **E**: A separate green substrate, suggesting a separate or final product.

The task is to match these lettered labels with their appropriate descriptions or roles in the enzyme cycle. This diagram could be illustrating stages in an enzyme-catalyzed reaction, showing how substrates interact with the enzyme and the resulting product formation.

Expert Solution
Step 1

Reactions can proceed forward or reverse reactions can proceed spontaneously without the help of catalysts. Catalysts can not make a non-spontaneous reaction spontaneous but they can speed up the process by decreasing the activation energy.
