A substance that is able to interact with an enzyme, reducing its ability to process a substrate, is called an inhibitor. If the inhibitor acts by temporarily attaching to an area other tham the binding site, causing a change in the shape of the enzyme's active site, it would be a(n) a. Irreversible inhibitor b. Competitive inhibitor c. Reversible inhibitor d. Noncompetitive inhibitor 2. Several factors can affect the rate of an enzyme-catalyzed reaction. The following four diagrams show how reaction rates are affected by pH, temperature, substrate concentration and the amount of enzyme. Which diagram best represents how changes in the substrate concentration affect the rate? a C While there are several theories used to explain how enzymes function, one popular one is call the induced-fit theory. Which of the following is the basis of that theory? 3. a. Different cofactors can be used by the same apoenzyme, allowing it to interact with an entire class of substrates. b. Variations in pH will alter enzyme activity. An enzyme is somewhat flexible and able to adapt to several substrates. d. Substrates able to adjust their shapes so that several can 'fit' an enzyme's binding site. с.
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.
Enzymes are a particular class of proteins that can catalyze biochemical reactions in the body. The enzyme binds to its substrate and converts it to a product. The catalysis of an enzyme can be inhibited by reversible and non-reversible inhibition.
