The P. multocida that are growing within Sam’s abscess are breaking glucose down

Question

The P. multocida that are growing within Sam’s abscess are breaking glucose down via glycolysis in order to obtain energy. This process occurs via a series of enzymatic reactions. During a chemical reaction, an enzyme functions as a biological catalyst and lowers the activation energy. How does an enzyme lower the activation energy of a reaction?

The enzyme increases the effectiveness of reactant collisions thereby increasing the number of reactant molecules that reach activation energy. As the enzyme is utilized, heat is released causing an increase in the reaction rate and a subsequent lowering in the energy of activation. The breakdown of the enzyme provides energy to the reactants allowing them to reach activation energy more quickly. The enzyme increases the potential energy available to the reactants, thereby decreasing the activation energy that must be reached.

Explanation / Answer

Enzymes are proteins which accelerate the rate of chemical reactions in a cell.
Enzyme catalyzed reactions are much faster. Enzymes lower the activation energy
so that reaction is speeded up. Thee enzymes are very specific. These enzymes increase
the collisions between reactant molecules so that they reach the activation energy state
because of energy released during collisions. When reactants reach activation energy
the chemical reaction take place. Hence option a is the correct answer.
