(3) Evaluate the following uses of catalysis in terms of the goals of green chemistry (it is up to you if you want to refer to the 12 Principles or just the more general goals proposed by Dr. Lipke). Identify benefits as well as possible downsides. 2 a. A catalytic process that uses O, to oxidize an organic substrate dissolved in hexanes as a solvent, replacing a previous process that required the use of pyridine-N-oxide as an oxidant. b. A catalytic process that allows organic plant matter to be broken down into small organic molecules that can be used to produce fuels and fine chemicals that would otherwise be made from petroleum. c. A catalytic process that uses a mercury salt to catalyze the oxidation of methane to a methanol derivative, circumventing a more traditional route using H, and CO to produce methanol as an intermediate.
Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.
