Match each inhibitor with its effect on Michaelis-Menten reactions. Group of answer choices Vmax and apparent Vmax are equal and the apparent Km is greater than Km. The apparent Vmax is less than Vmax and the apparent Km and Km are equal The apparent Vmax and the apparent Km are both lowered to the same
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.
Match each inhibitor with its effect on Michaelis-Menten reactions.
Michealis menten kinetics can be described by using the following equation:
Where V is velocity of the reaction
Vmax is the maximum velocity
[S] is the substrate concentration
Km is the Michealis Menten constant or the substrate concentration at which half of the maximum velocity is reached.
The same equation can be rearranged into Equation shown below called as Lineweaker Burk equation:
A plot of 1/V vs 1/[S] gives a straight line.
In the next section we see how inhibitor effects the Km and Vmax of a reaction.
