Penicillin functions by inhibiting an enzyme, transpeptidase, that catalyzes the last step in the bacteria's metabolism which synthesises bacterial the cell-wall. Why does inhibition of this enzyme make Penicilin such an effective medicine in humans, with so few side effects? A. Inhibiting enzymes like this always slows the metabolism of an organism. B. The enzyme is not inhibited in humans because we have resistance to the penicillin. C. The enzyme is part of an essential pathway in the bacteria, which does not exist in humans. D. Inhibiting the enzymes stops respiration in the bacteria, killing quickly
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.
