Which statement is NOT completely true? O In the Induced-fit theory, the conformation of the active site changes to accommodate an incoming substrate. O A urease which hydrolyzes only urea is an example of an enzyme that exhibits relative specificity. O Cofactors that are organic also go by the name coenzymes O Many enzymes require a second substance present (cofactor) in order to be active. O Enzymes are protein based catalysts. O Enzymes are sensitive to heat and pH O Enzymes catalyze at their "active site". O Apoenzymes are inactive enzymes.
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.
