The reaction represented by this graph is a burning reaction involving the reactants glucose (C6H12O6) and also oxygen (O2). The commodities of the reaction room carbon dioxide (CO2) and water (H2O). Energy is additionally released during the reaction. The enzyme speeds up the reaction through lowering the activation energy needed because that the reaction come start. To compare the activation power with and without the enzyme.

You are watching: What effect do enzymes have on activation energy

Enzymes typically lower activation power by reducing the energy needed because that reactants to come together and also react. For example:

Enzymes might also allow reactions to take place by different pathways that have lower activation energy.

The energetic site is particular for the reaction of the benidormclubdeportivo.orgchemical reaction the enzyme catalyzes. Comparable to puzzle pieces fitting together, the active site deserve to only bind particular substrates.


This enzyme molecule binding reactant molecules—called substrate—at its active site, developing an enzyme-substrate complex. This bring the reactants together and also positions them properly so the reaction can occur. After the reaction, the assets are released from the enzyme’s energetic site. This frees increase the enzyme for this reason it can catalyze added reactions.

The activities of enzymes likewise depend top top the temperature, ionic conditions, and also the pH the the surroundings. Part enzymes work best at acidic pHs, while rather work best in neutral environments.

benidormclubdeportivo.orgchemical reactions are optimal at physiological temperatures. Because that example, mostbenidormclubdeportivo.orgchemical reaction work best at the typical body temperature the 98.6˚F. Many enzymes lose duty at reduced and greater temperatures. At higher temperatures, an enzyme’s shape deteriorates. Only when the temperature comes back to normal does the enzyme restore its shape and also normal activity.
