When an enzyme is frozen, it only slows down activity. Unlike boiling an enzyme, it does not stop it from working.

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 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.
How does the effect of freezing differ from the effect of boiling the enzyme?
Freezing doesn't effect the enzymes since freezing does not permanently affect enzyme structure. Boiling permanently changes the structure and can change the enzymes.
What blocks enzyme activity by binding to allosteric site of an enzyme causing the enzyme's active site to change shape?
An allosteric inhibitor stops enzyme activity by binding to an allosteric site and causing the conformation of the enzyme to change.
What does activity of an enzyme depend on?
The concentration of hydrogen ions in solution affects the enzyme activity. Each enzyme has maximal efficiency under an optimum pH. Since pH is one of the factors for the denaturation of proteins, if an enzyme is submitted to a pH level under which it is denatured there will be no enzymatic activity.
What are the effects of physical activity on enzyme activity?
Physical activity can alter the shape of enzyme which can cause damage or may the enzyme become inactive
Does freezing a enzyme affect it?
When an enzyme is frozen, it only slows down activity. Unlike boiling an enzyme, it does not stop it from working.
How would one overcome the effects of a competitive inhibitor on enzyme activity in the biochemical regulation of metabolic pathways?
Increase the amount of substrate for the enzyme.
What is an example of a sentence using the word 'enzyme'?
"During this experiment, we will be looking to see the effects of heat on enxyme activity" "This stain remover contains an enzyme"
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 is the effect of hydrochloric acid on the enzyme activity?
Denature enzyme activity
What switchs on enzyme activity while what can switch off or reduce enzyme activity?
activators; inhibitors
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 can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
How does the effect of freezing differ from the effect of boiling the enzyme?
Freezing doesn't effect the enzymes since freezing does not permanently affect enzyme structure. Boiling permanently changes the structure and can change the enzymes.
Which blocks enzyme activity by binding to the site of an enzyme?
inhibitor
What accurately describes how temperature affects enzyme activity?
Enzyme activity increases with temperature, but only up to a point.
