Explain how enzymes speed up chemical reactions. What is a factor that could speed up or slow down enzyme speed? Need cites and paraphrase!

Solution

Enzymes speed up chemical reactions, as they act as catalysts. The enzymes lower the activation energy needed to run the reaction. Due to the presence of enzymes during a reaction, not only the activation energy gets reduced, but also the rate of reaction increases. Thus enzymes speed up the reactions. The substrates have to bind to the active sites/hot spots of the enzyme to run the reaction. The active sites of the enzymes have amino acids (hydrophilic /hydrophobic /neutral /+ve /-ve) which catalyze the reactions. The active site of the enzymes upon binding to the substrate molecule, modify the structure of the substrate forming products. The rate of the reaction depends on the amount of substrate, enzyme, product, pH in which the reaction has been taken place and any inhibitors (competitive, non competitive, feedback inhibition). An inhibitor which can change the shape of active site of an enzyme or end products formed in excess can slow down the rate of reaction or enzymatic action.
