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.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
