Which of the following statements are correct? explain your answers.a. The active site of an enzyme usually occupies only a small fraction of the enzyme surface.B. catalysis by some enzymes involves the formation of a covalent bond between an amino acid side chain and a substrate molecule.c. a β sheet can contain up to five strands, but no more.d. The specificity of an antibody molecule is contained exclusively in loops on the surface of the folded light-chain domain.e. The possible linear arrangements of amino acids are so vast that new proteins almost never evolve by alteration of old ones. f. allosteric enzymes have two or more binding sites. G. noncovalent bonds are too weak to influence the three- dimensional structure of macromolecules.
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.
