A hollow fiber enzyme reactor (HFER) consists of 5000 fibers. Each fiber has an internal diameter of 0.04 cm, and on the inside surface of the fibers, an enzyme has been immobilized that removes a toxin from plasma that is flowing through the inside of the fibers. The enzyme reaction is very fast, so a reasonable assumption is that the concentration of the toxin at the surface of the hollow fiber is equal to zero. The /HFER operates at 37°C, and the plasma enters at a total flow rate of 200 mL/min. The concentration of the toxin in the plasma that enters the HFER is 1 mg/L, and its MW is 636 g/mol. If the fibers in the HFER are 50 cm in length, what is the concentration of the toxin in the plasma as it leaves the HFER?
Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.
