Which of the following environmental conditions that can affect the rate of an enzyme catalyzed reaction?

The temperature and pH of the environment, as well as the concentration of the substrate and enzyme, all affect the rate at which an enzyme catalyzes a reaction.

What environmental factors affect enzyme activity?

Enzyme activity is influenced by several environmental factors such as temperature, salt, pH and substrate concentration. Low or high values of these factors will cause alteration in a structure that will further disrupt the functioning. Therefore, the correct answer is (e) temperature, pH, and salt.

What can change the rate of an enzyme catalyzed reaction?

The rate of an enzyme-catalyzed reaction increases with an increase in the concentration of an enzyme. At low temperatures, an increase in temperature increases the rate of an enzyme-catalyzed reaction. At higher temperatures, the protein is denatured, and the rate of the reaction dramatically decreases.

How does environmental pH affect reaction rate?

Environmental pH can alter the efficiency of enzyme activity, including through disruption of hydrogen bonds that provide enzyme structure. Each enzyme has an optimum pH range. … Once all of the substrate is bound, the reaction will no longer speed up, since there will be nothing for additional enzymes to bind to.

What are the 4 factors that affect enzyme activity?

Several factors affect the rate at which enzymatic reactions proceed – temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

What are enzyme catalyzed reaction?

Enzyme catalysis is the increase in the rate of a process by a biological molecule, an “enzyme”. Most enzymes are proteins, and most such processes are chemical reactions. Within the enzyme, generally catalysis occurs at a localized site, called the active site.

How does temperature affect the rate of enzyme reaction?

As with many chemical reactions, the rate of an enzyme-catalysed reaction increases as the temperature increases. However, at high temperatures the rate decreases again because the enzyme becomes denatured and can no longer function. It is now denatured. …

What inhibitor affects the rate at which the enzyme catalyzed reaction occurs?

Competitive inhibitors impair reaction progress by binding to an enzyme, often at the active site, and preventing the real substrate from binding. At any given time, only the competitive inhibitor or the substrate can be bound to the enzyme (not both).
