What equation is represented by E + S = ES = E + P?

The equation E + S = ES = E + P describes the process of enzyme catalysis. Here, "E" represents the enzyme, "S" represents the substrate, "ES" represents the enzyme-substrate complex, and "P" represents the product. This reaction pathway illustrates how an enzyme interacts with a substrate to form a temporary complex (ES), which eventually leads to the formation of the product (P) and the regeneration of the enzyme (E).

This is a fundamental aspect of the catalytic mechanism, demonstrating how enzymes facilitate biochemical reactions without undergoing permanent changes themselves. It highlights the sequence of events from substrate binding to product release, which is essential for understanding how enzymes function in biological systems.

In contrast, the other options relate to different concepts in biochemistry. The Henderson-Hasselbalch equation is used to calculate the pH of a buffer solution and illustrate the relationship between pH, pKa, and the concentrations of acid and conjugate base. The Lineweaver-Burk plot is a graphical representation used to determine kinetic parameters of an enzyme-catalyzed reaction, particularly the Michaelis constant (Km) and maximum velocity (Vmax), but it does not describe the catalytic mechanism itself.
