What is varied when tested the effect of pH enzyme activity?
The pH is varied to effect, by its affect, this test.
What is the effect of pH upon the relative enzyme activity?
Different enzymes work best at different pH. This is refered to as the ideal pH for the enzyme. For example, the digestive enzyme trypsin works best at an acidic pH while alkaline phosphatase works best at a basic pH. Therefore, enzyme activity varies with pH and this variation depends on the enzyme being studied
What are the two factors that effect the efficiency of an enzyme?
Two factors that affect the efficiency of an enzyme are temperature and pH. Enzymes work best within a specific temperature and pH range, and deviations from these optimal conditions can denature the enzyme leading to decreased efficiency. Additionally, substrate concentration plays a role in enzyme efficiency as higher substrate concentrations can lead to faster reaction rates until all enzyme active sites are saturated.
What happens to an enzyme-substrate reaction when the enzyme has been subjected to heat or high-low pH?
When an enzyme is subjected to heat or extreme pH levels, it can denature, losing its specific shape and functionality. This can affect the enzyme's ability to bind to the substrate and catalyze the reaction efficiently. In extreme cases, the enzyme may become permanently inactivated.
What must be held constant when testing the effect enzyme concentration on enzyme activity?
temperature,pH and substrate concentration
What is varied when testing the effect of pH on enzyme activity?
pH

How does heat effect pH level?
Heating pure water the pH decrease.
What variable did you test in each setup?
We tested the effect of different temperatures on enzyme activity in Setup 1 and the effect of varying pH levels on enzyme activity in Setup 2.
How does pH levels effect an enzyme?
Changes in pH levels can alter the shape and charge of the active site of an enzyme, affecting its ability to bind with the substrate. This can either enhance or inhibit enzymatic activity, depending on the specific enzyme and its optimal pH range. Extreme pH levels can denature the enzyme, rendering it inactive.
How can you determine the optimum pH of an enzyme?
To determine the optimum pH of an enzyme, you can conduct experiments at different pH levels and measure the enzyme activity. The pH at which the enzyme shows the highest activity is considered its optimum pH.
How does adding an acid to an enzyme reaction effect the enzyme?
it alters the pH of the enzyme denaturing it leaving it unable to carry out it's role effectively or at all
