Complete the following paragraph describing the advantages and disadvantages of allosteric regulation versus covalent modification. Allosteric regulation occurs when an enzyme is activated or inhibited through noncovalent interaction with a [ In allosteric regulation the effector binds to the enzyme at therefore, the process is regulated by the immediate concentration of the effector. The effector molecules are to the substrate. The advantage of this type of regulation is that the cellular response can be The major disadvantage is that signals not directly involved in the pathway often the regulation Covalent modification allows for input not directly in the metabolic pathway and have methods by which the modifying enzymes can be stopped and covalent modification removed. effects. However, the disadvantage is the necessity of having
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.
