The effect of pH on a certain enzyme is shown in the graph. At what pH would the enzyme be most effective?

Answer:

2

Explanation:

The enzyme will be the most effective between 8 and 10

The enzyme will show maximum activity in the range of pH between 8 and 10. This can be the enzyme's optimum pH as at this range it is found to be most effective. Thus, the correct option is 2.

Enzymes are the biocatalysts. They act as enzymes in the biochemical reactions by reducing the activation energy required by the reactants to form products. Enzymes remain unused in a reaction.

Enzyme activity depends upon different factors which include temperature, pressure, pH, etc. Enzymes show maximum activity at the optimum conditions of these environmental factors.

From the given graph, it can be interpreted that the enzyme shows maximum rate of action between the pH range of 8 and 10. Thus, this is the optimum range of pH.

Therefore, the correct option is 2.

Objective(s):
In your own words, what was the purpose of the lab?


Hypothesis:
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.


Procedure:
Complete your hypothesis (above).

Identify the independent (test) variable and the dependent (outcome) variable: __________________________

Practice using the computer model. Select each marker to see what it does. Here is a summary you can refer back to as you complete your experiment.
Carbon Dioxide Emissions Slider: You will use the arrows to change the amounts of carbon emissions.
Time Step Size: This will allow you to view the data every 5 years or every 10 years.
Start Over: Use this to reset the model if needed.

The current carbon emissions are 9.8 gigatons, or 9.8 billion tons. Complete all three scenarios to find out what happens to the global temperature if these emissions stay the same, decrease, or increase over the next century. Follow the instructions in the Data section of this report.

Data:
For each scenario, record the carbon dioxide emission rate and the global temperature. The data for the years 1960–2010 are already filled out for you.

Scenario One: Carbon dioxide emissions stay the same
Set the carbon dioxide emissions rate to 9.8 gigatons.
Set the time step size to 10 years.
Select step forward until you have the data through the year 2110.
Record the data in the table below.
Year Carbon Emissions (gigatons) Temperature (Fahrenheit)
