In an enzyme-substrate reaction, what does vmax refer to? the maximum speed at which product is converted to substrate the maximum speed at which substrate is converted to product the maximum concentration of product produced by the reaction the maximum concentration of substrate consumed by the reaction

The maximum speed at which substrate is converted to product

Explanation:

Vmax is the maximum value of the initial reaction rate when all active sites are occupied. This point is reached when there is sufficient substrate to completely saturate the active site of the enzyme.

However, it is not proven that it is possible for an enzyme to reach maximum speed in a real reaction due to a short delay during the substrate binding and release process at the active site.
