Abstract: The purpose of this paper is to inform the reader how to determine SN1 and SN2 reactions. Introduction: Substitution reactions are considered as SN1 or SN2 both consisting of nucleophiles. Substitution reactions that are SN2 consist of 2 reactants and two new products. In SN1 reactions consist of a unimolecular process. A nucleophile is electron rich which allows electrons to be donated to a carbon. An electrophile is an electron poor species that accepts electrons. Substitution reactions consist of an alkyl halide, or a substrate, or electrophile, a nucleophile, a product, and a leaving group. The product is the substance that is produced at the end of the reaction. Lastly the leaving group is the species that leaves or breaks from the electrophile. Discussion: In a SN2 reaction the nucleophiles replace the leaving group. Then the nucleophile will attack the substrate, and donate an electron pair to new bonds, and then it will replace the leaving group which …show more content…

Notice in the transition state of the mechanism that the nucleophile is forming bonds. Lastly the leaving group is leaving to produce the final product of the mechanism. In a SN1 reaction the nucleophiles function the same as in the SN2 reactions. The difference in the SN1 reaction is that it is unimolecular which only consist of one reactant. The rate of the reaction is solely dependent on one reactant and the process occurs in two steps. In these two steps the leaving group will leave and allow the substrate to produce a carbocation intermediate. Secondly the nucleophile then prepares itself to attack the carbocation that was formed, in order to produce the final product. In these reactions there is a slow step and a fast step on how the mechanism can be carried out. An example of the slow step and fast will be provided

One of the ways they can do this is through substitution reactions. There are two different types of substitution reactions, SN1 and SN2. Substitution reactions are when one atom or ion is substituted for another. An SN1 reaction is a unimolecular, nucleophilic substitution that is 1st order. However, an SN2 reaction is a bimolecular, nucleophilic substitution that is 2nd order.

Each amino acid is made up of an amino group, a carboxyl group and a side chain (Reece, J. B., Urry, L. (2016). Campbell biology. Boston Pearson). Enzymes work by lowering the activation energy of the reaction making the reaction produce faster. Enzymes begin to catalyze chemical reactions with the binding of the substrate to the active site on the enzyme.

Introduction Chemical reactions are seen in many instances, including those in which one substance is being converted to another. Natural chemical reactions will occur without intervention, however they occur slowly. Enzymes become important in these situations. Enzymes are proteins that act in cells to ensure reactions occur at appropriate speeds. In other words, they act as catalysts.

Enzyme speed chemical reactions by lowering the activation energy, activation energy is the energy require for chemical reactions to take place. Enzyme is the ES complexes that lower the activation energy. There are two ways to form product in enzyme, one is two substrates to form one product in one active site or one substrate break down into two products. If two substrate molecules need to be joined to form one product, two substrates need to attached to the enzyme holds them close together, reducing any repulsion between the substrate molecules so they can bond more easily to form one product. If the enzyme is catalysing a breakdown reaction, it means one substrate breakdown into two products, one substrate molecule fitting into the active

This reacting molecule that binds to the enzyme is called the substrate. The reaction containing the enzyme occurs in two stages where s represents the substrate, E the enzyme and P the product, E + S ↔ ES ↔ E + P. Enzyme catalyzed reactions can be either anabolic or catabolic. Anabolic reactions are those where small molecules are linked together to form large complex molecules. Conversely,

These molecules must collide with enough energy to overcome the energy barrier to reaction (activation energy.) The activation energy is the minimum amount of energy required for two molecules to undergo a reaction. The active site of an enzyme has the right shape and functional groups to bind to the reacting molecule called the substrate. A simple model to represent how an enzyme works is the lock and key analogy. In this example, the enzyme is the lock, and the key is the substrate.

The energy to break the existing bonds in the molecule needs to be overcome before the reaction can take place, this is called the activation energy. A catalysed reaction takes a different reaction pathway with a lower activation energy (figure 1), this in turn speeds up the rate of the reaction. The active site is where the substrate binds to the enzyme as it is a complimentary shape to the substrate, it has the correct molecules in the right places in order to bind and form the enzyme substrate
