What is the effect of cold temperatures on enzyme activity?
Cold temperatures have a drastic effect on an enzyme's activity level. Cold temperatures usually dramatically slow down an enzyme's activity.
Why Extracellular enzyme activity is easier to determine compared to Intracellular enzyme?
It is because extracellular enzymes act under very hostile conditions in nature, so their activity is more resistant than intracellular activity.
What happens when an enzyme catalyzes a reaction?
The rate of a reactions usually increases when catalyzed by an enzyme. For maximum rate of activity, the enzyme needs optimal conditions.
What can you do to regain the activity of the enzyme?
The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
What conditions affects the function of enzymes?
The activity of an enzyme is affected by temperature, pH and the concentration of the substrate.
What is the effect of hydrochloric acid on the enzyme activity?
Denature enzyme activity
What is the effect of cold temperatures on enzyme activity?
Cold temperatures have a drastic effect on an enzyme's activity level. Cold temperatures usually dramatically slow down an enzyme's activity.
What is varied when testing the effect of pH on enzyme activity?
pH
What is the enzyam activity?
The enzyme activity depends on the conditions of the reaction and the enzmye used. The term enzyme activity refers to the rate at which substrate is converted into product and can be measured in many different ways.
What is varied when tested the effect of pH enzyme activity?
The pH is varied to effect, by its affect, this test.
Why Extracellular enzyme activity is easier to determine compared to Intracellular enzyme?
It is because extracellular enzymes act under very hostile conditions in nature, so their activity is more resistant than intracellular activity.
The enzyme phosphofructokinase is an important enzyme that plays a significant regulatory role in glycolysis. Which of the following conditions would be expected to result in increased activity of this enzyme?
Low levels of ATP
What happens when an enzyme catalyzes a reaction?
The rate of a reactions usually increases when catalyzed by an enzyme. For maximum rate of activity, the enzyme needs optimal conditions.
What must be held constant when testing the effect enzyme concentration on enzyme activity?
temperature,pH and substrate concentration
What can affect enzyme activity?
pH Temperature Substrate Concentration non-ideal conditions will ultimately lead to the denaturing of the enzyme
How does initial concentration of substrate effect enzyme activity?
At low concentration of substrate , rate of enzyme action is directly proportional to conc. of substrate .
What is the Effect of mineral and vitamin deficiency on enzyme activity?
many vitamins and minerals play crucial roles in many metabolisms as coenzyme or cofactor. Deficiency of those lower the related-enzyme activity.
