substrate concentration

Substrate concentration refers to the amount of a substance that an enzyme works on during a chemical reaction. In biological systems, enzymes help facilitate reactions, and the substrate is the specific molecule that these enzymes target. A higher substrate concentration means more molecules are available for enzymes to interact with, potentially increasing the rate of the reaction. However, this increase continues only up to a point, after which the enzymes become saturated, and adding more substrate won’t speed up the reaction further. Understanding substrate concentration is essential in fields like biochemistry and medicine, as it affects how reactions occur in living organisms.
