One of the factors that affects enzyme activity is the pH. If there are small changes in the pH, the enzyme will denature and catalytic activity will be lost.Continue Reading
Another factor is the temperature. Enzyme-catalyzed reactions will have the rate increased as the temperature increases. Because the enzymes are proteins, they will become denatured and turn inactive at the higher temperatures.
The concentration of the enzyme also affects the activity. If the concentration of the enzyme is increased while the concentration of the substrate is kept constant, the rate of the reaction will double as the enzyme concentration doubles. This is due to the fact that the molar concentration of the enzyme being used almost always will be lower than the molar concentration of the substrate.Learn more about Organic Chemistry
A change in the pH, or acidity level, can change the shape of an enzyme, preventing it from fulfilling its purpose, according to a Florida State University biochemistry laboratory manual. According to Elmhurst College, enzymes increase the rate of cellular reactions.Full Answer >
Allosteric control occurs when a small regulatory molecule causes the inhibition or activation of an enzyme at an allosteric site rather than the active site (the region of the enzyme that binds to substrates, where catalytic activity occurs). Another name for allosteric control is allosteric stimulation.Full Answer >
Organic activity, with regards to weathering and erosion, is defined as the activity of plants and animals that cause physical weathering of landforms. This activity includes tree roots growing into crevices, lichens growing on rocks and animals burrowing into dirt.Full Answer >
Uncompetitive inhibition is important in the study of enzyme chemistry because it describes a specific method of reducing the activity of enzymes in a catalytic reaction. This type of inhibition involves an inhibitor compound that connects with the enzyme-substrate complex to prevent the creation of the product. Uncompetitive inhibition has been found to be useful in the field of medicine and other scientific fields.Full Answer >
