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.

A reaction occur if the substrates needed collide with each other. Enzyme is like a mold that can hold the substrate so that it will be easier to collide. The effect of enzyme could be seen in the activation energy needed to do the reaction because enzyme lower it very much. This will help speed up the reaction so it create product faster.

d. changes in climate and historical records

hope this
