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.Know More
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
An enzyme is in the class of organic compounds or molecules known as proteins or polypeptides. Enzymes play a role in reactions at the cellular level.Full Answer >
In general, the rates of enzyme-catalyzed reactions are faster as temperature increases and slower as temperatures decrease below an optimal temperature level. When temperature increases, more molecules have more kinetic energy to react, so reaction speed increases. As temperature decreases, so does the available energy, and then the reaction is slowed.Full Answer >
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 >
Factors that influence enzyme activity include substrate concentration, enzyme concentration, temperature, pH and the presence of any activators or inhibitors. Enzymes act as catalysts for biochemical activities.Full Answer >
