12.) Using graph 1, explain how enzymes work. Include the term activation energy and compare the two curves,
seropon [69]

Answer:

Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks.

Explanation:

To understand more about working of enzyme and its activation energy lets consider few points:

• In biochemical processes, molecules require energy in order to start a reaction. For example, molecules need to have some kinetic energy, or velocity, to collide with other molecules to initiate a reaction. If the collisions don't happen often or don't have enough kinetic energy, no reaction will take place. The energy required to start a reaction is called the activation energy.

• Reactants and products have specific energies. In order to transform the reactants into products, the reactants would have to go through a transition state which is usually higher in energy.

• In this graph we see the plot of energy versus the progress of a reaction. Reactants have higher energy than products. The energy of the reactants increase and then decrease to the final product energy. The highest point in the curve represents the energy of the intermediate state in the reaction. The energy required to achieve the intermediate state is the activation energy of the reaction.

Thus, we conclude that enzyme requires certain amount of energy to complete the reaction and that energy is known as activation energy for the reaction.
