12. Nirogenase is an enzyme that converts the remarkably stable triple bond in N2 into a usable form. It uses an iron sulfur cluster comprised of iron and the sulfur atoms of several active site cysteine residues. Based on your knowledge of Biochemistry what is the enzyme doing to effectively carry out this reaction? a) stabilizing the transition state for the reaction by hydrophobic effects b) stabilizing the ground state for the reaction by hydrophobic effects c) stabilizing the transition state for the reaction by metal ion catalysis d) stabilizing the ground state for the reaction by metal ion catalysis e) all of the above
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.
