Is it true that enzymes interact with specific substrates?

Other enzymes help bind two molecules together to produce a new molecule. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site.

Hereof, why do enzymes only work on their specific substrates?

Because of the certain shape they have. Amino acids can only bind with specific active sites or specific substrates. According to the lock and key model, the enzyme has to be the exact shape of the substrate to fit and connect.

One may also ask, what 4 things can affect the way enzymes work? Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

Subsequently, one may also ask, how do enzymes bind to substrates?

Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products. The enzyme's active site binds to the substrate.

What is substrate specificity?

Specificity is the ability of an enzyme to choose exact substrate from a group of similar chemical molecules. The specificity is actually a molecular recognition mechanism and it operates through the structural and conformational complementarity between enzyme and substrate.
