Design an experiment in which you will test theeffect of an acidic fluid on enzymatic activity. (Recall: enzymesare proteins.) To complete this project, it may be useful for youto review theScientific Method Tutorial (found theCourse Content section of the classroom under the Science LearningCenter link) and the Scientific Method lab (Lab 1), so thatyou can better understand how to design an experiment. It may alsobe helpful for you to review Lab 4 (Enzymes). As you review Lab 4,you will be reminded that there are several factors that impactenzymatic activity: pH, temperature, and amount of reagent. Feelfree to refer to observations and information from Lab 4 as youcomplete the questions required in the Final Applied Project (seethe questions below).

As you design your experiment for this project,please remember that you are trying to examine how an acidic fluidwill modify the outcome of an enzymatic reaction. To successfullycomplete this project, you will need to identify the question(s)being asked in your experiment and the hypothesis that you aretesting. In your experimental design, you must clearlyexplain what you are doing. That means that you will need toidentify the enzyme and the acid, as well as explain yourexperimental protocol (this information will help you to answerquestion 2). You must also thoroughly explain how the addition ofthe acidic fluid impacted the overall reaction process (thisinformation will help you to answer question 4).

Hint: Keep in mind that the acid will changethe environmental conditions of the experiment (for example, a lowpH value could change the shape of the active site on the enzymeprotein), without directly participating in thereaction.

Lab Materials

You may need the following, depending on yourexperimental design.

Materials in your lab kit:

• none

Additional materials you may need:

• plastic beakers or cups
• hydrogen peroxide solution (from Lab4)
• yeast (from Lab 4)
• sample of fresh meat, about 1 cm cubed insize (unprocessed and uncooked, e.g., liver, steak, fish, orpoultry%u2014particularly organs)
• sample of fresh vegetable, about 1 cmcubed in size (e.g., potatoes or other root vegetables)
• a pen for labeling the beakers orcups
• a ruler with centimeter markings

Remember, the goal of this project is for you toevaluate the effect of an acid on enzymatic activity. As part ofthis assignment, you must identify your source of enzyme and theacid used. As you work though this project, you must also make surethat the following questions/points are addressed:

1. What question are you asking? Clearly state yourhypothesis.

2. Design an experiment. Provide a detailed account of thematerials and methods used to conduct the experiment. Also includethe methods for data collection and analysis.

3. Conduct the experiment and record your results below. Whatdid you observe? Which samples showed bubbling?

4. Use your knowledge about factors that effect enzymaticactivity to interpret your results. It may be necessary for you torefer to your lab manual and/or other resources. What effect didthe acid have on the enzyme?

5. Was your hypothesis supported? What is your conclusion?Explain your answer.

6. Cite all references used to complete your Final AppliedProject.

Choose an important question about blood pressure machines concept that you can answer via prototyping to reduce overall project risk. Design a model and accompanying test(s) will best enable you to address the question. Construct a simple/crude prototype and execute tests.

Suppose a weather forecast reports that the probability of snow this week is 0.18. The forecast states that if it snows this week, the probability that it snows next week is 0.29. If it does not snow this week, the probability that it snows next week is 0.12. The tree diagram depicts the possible weather event outcomes with the associated probabilities.

What can be done to reduce corruption in zimbabwe?

A nuclear power plant is 25% efficient, meaning that only 25% of the power it generates goes into producing electricity. The remaining 75% is wasted as heat. The plant generates 8.20 108 watts of electric power. If each fission releases 2.07 102 MeV of energy, how many kilograms of are fissioned per year?

We are observing wasted heat in everyday life for example in Pakistan heavy generated are installed, during their supply of electricity an excessive amount of wasted heat is produced in its surrounding, similarly when we drive a vehicle a heat is available in the surrounding of engine of that vehicle, we can also see many more such examples of wastage of heat. This heat is effecting the environment of Pakistan badly.

Is it conceivable to convert this wasted heat into some useful work/energy/electricity or not. If yes how? If no why?”
