Substrate
(Redirected from Substrates)
Substrate refers to the material or substance on which an enzyme acts. It is a key concept in Biochemistry and Molecular Biology, playing a crucial role in various biological processes.
Overview[edit | edit source]
In biochemistry, a substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate binds with the enzyme active site, and an enzyme-substrate complex is formed. The substrate is transformed into one or more products, which are then released from the active site. The active site is now free to accept another substrate molecule. In the case of more than one substrate, these may bind in a particular order to the active site, before reacting to produce products.
Role in Enzyme Activity[edit | edit source]
The substrate plays a significant role in Enzyme Activity. The enzyme's active site binds to the substrate and facilitates its conversion to a product. This process is often represented by the lock and key model, where the enzyme (the lock) recognizes a specific substrate (the key).
Substrate Specificity[edit | edit source]
Substrate Specificity is a critical concept in biochemistry. It refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules. The specificity is actually a molecular recognition mechanism and is a result of the structural complementarity between the enzyme and the substrate.
