Which variable does not affect enzyme activity?
Enzyme concentration does not affect the enzyme activity directly as substrate concentration determine it until the presence of the substrate in an excess amount. Enzymes are the assemblage of protein subunits and hence function under specific temperature and pH range only.
What does not affect the function of an enzyme?
The correct answer: The factor which does NOT affect enzyme activity is d. Free Energy. The enzyme activity varies with the changing physical…
What are the 4 factors that affect enzymatic function?
Several factors affect the rate at which enzymatic reactions proceed – temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.
Which independent variables affect how enzymes function?
The independent variable is the concentration of enzyme, the concentration of the substrate, the temperature, and the addition of an inhibitor. Introduction: Enzymes are proteins that carry out chemical reactions.
What are factors affecting enzyme activity?
The six factors are: (1) Concentration of Enzyme (2) Concentration of Substrate (3) Effect of Temperature (4) Effect of pH (5) Effect of Product Concentration and (6) Effect of Activators. The contact between the enzyme and substrate is the most essential pre-requisite for enzyme activity.
What environmental conditions can disrupt these bonds?
Temperature or heat energy can affect the functioning of an enzyme, as if there is too much energy the atoms forming the enzyme and substrate will shake about and bonds will break, meaning the enzyme becomes broken and useless.
Which of the following does not affect the velocity of an enzyme catalyzed reaction?
Which of the following does not affect the velocity of an enzyme-catalyzed reaction? Explanation: The size of an enzyme is typically not indicative of the rate of the reaction that it catalyzes. All other parameters are taken into account when considering reaction velocity.
How does a substrate affect an enzyme?
(B) As the concentration of substrate increases, the enzyme becomes saturated with substrate. As soon as the catalytic site is empty, more substrate is available to bind and undergo reaction. … The rate of reaction when the enzyme is saturated with substrate is the maximum rate of reaction, Vmax.
How does denaturation affect enzyme function?
Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. The enzyme will have been denatured . … The enzyme, including its active site, will change shape and the substrate no longer fit. The rate of reaction will be affected, or the reaction will stop.
How does cellular environment affect enzyme activity?
Environmental pH can alter the efficiency of enzyme activity, including through disruption of hydrogen bonds that provide enzyme structure. The relative concentrations of substrates and products determine how efficiently and enzymatic reaction proceeds.
