State one way extremely high temperatures can affect biological catalysts found in these organisms?
extremely high temperatures can decrease the rate of enzyme action very quickly ,the enzyme becomes deactivated (enzyme does not work)
Why might enzyme's activity decrease at very high temperatures?
Enzymes activity is affected by temperature. At a very high temperature, enzymes became denature that means they lose their original shape, which is important for them to react. Thus, enzyme activity decreases at a very high temperature.
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.
Will enzyme activity increase with an increase in temperature?
Warmer temperatures mean little more than that molecules are moving more rapidly. This promotes enzyme activity on its own, however, as movement allows the enzymes to react to more material in a shorter amount of time.
Did the addition of acid increase or decrease the activity of catalase?
Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide into water and oxygen. It requires an optimum pH of 7 to properly function, thus the addition of acid will decrease or deactivate the enzyme.
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.

Changes in pH or temperature decrease enzyme activity because bonds break and the enzyme returns to its tertiary structure?
Changes in pH or temperature decrease enzyme activity because bonds b reak and the enzyme returns to it's PRIMARY structure. (not tertiary)

Changes in temperature and pH can decrease an enzyme's activity by breaking?
Hydrogen bonds
How does temperature affects activity?
The enzyme activity increases as the temperature rises due to the substrates colliding with the enzymes' active sites more frequently at higher temperatures. However, each enzyme has an optimum temperature as high temperatures denature enzymes.
In cell isolation why must cold buffer and centrifugation be carried in cold temperatures?
TO STOP ENZYME ACTIVITY
How does temperature affect fish?
Temperatures affect speed of metabolism, enzyme activity, and the blood's ability to carry oxygen.
Will enzyme activity increase with an increase in temperature?
Warmer temperatures mean little more than that molecules are moving more rapidly. This promotes enzyme activity on its own, however, as movement allows the enzymes to react to more material in a shorter amount of time.

Catalase is an enzyme that catalyzes the decomposition of hydrogen peroxide into water and oxygen. It requires an optimum pH of 7 to properly function, thus the addition of acid will decrease or deactivate the enzyme.
What are the optimum temperature and the optimum pH of an enzyme?
Every enzyme works at its maximum rate at a specific temprature called as optimum temprature for that enzyme. AND all enzymes work at their maximum rate at narrow range of pH, called as optimum pH. A slight increase or decrease in pH causes the retardation in enzyme activity or blocks it completely.
