Lab Chemistry of Life: Experiment

Experiment 1: Testing for Proteins

1. What can you conclude about the molecular make-up of egg whites based on the test you performed? Why might these foods contain these substances?

2. Diet and nutrition are closely linked to the study of biomolecules. How should you monitor your food intake to ensure the cells in your body have the materials necessary to function?

3. Insert a photo showing the final color in the test tubes for each of your solutions. Make sure the photo shows your name, face and date.

Experiment 2: Exploring Cell Size

1. How are organic molecules produced?

Post-Lab Questions

1. Insert a photo of your blocks after the 7-minute mark. Make sure you include your name, face and date in the photo

2. How did the surface area and volume effect the diffusion of the block?

3. How did the surface area to volume ratio effect the diffusion?

4. How does this experiment demonstrate the need for larger cells to divide?

5. Determine the surface area, volume, and surface area to volume ratio for the following three blocks. Then, state which one you believe would be the most efficient as a cellular morphology, and write a summary stating why.

This assignment is about a practical laboratory work to analyse certain basic concepts of life. This report was focused towards identifying the principle behind the cell size. The surface area to volume ratio was measured with respect to the diffusion rate. The corresponding association among cell size and diffusion was explored.

Example of incorrect table/graphic description: Table 1. Bacteria counts and water level for the Blackwater River Example of correct table/graphic description: Table 1. Bacteria counts and water level for the Blackwater River in the summer of 2015. Bacteria were sampled using 3 point cross sections along a 10 mile stretch of the Blackwater River. Samples show that as water level decrease so do bacteria counts. During higher flow levels bacteria levels increase. The results show that the area sampled is impaired for contact recreational use. The discussion section is where you interpret the results. You should also discuss the results in context of the overall experiment as identified in the introduction of the report. You should tell the reader why the data looks like it does and why it is important to know. Lastly you should discuss potential modifications for the experiment. What kind of changes would you make to this experiment to further knowledge of enzymes? This is not to correct mistakes but usually every experiment ends with more questions than you start with. How would you address those questions in future research?

Lab reports for this course project will have the following style. Use 12 point font The report should be written in the 3rd person. Do not use personal pronouns (I, us, we). Example written incorrectly in 1st person: I applied 5mL of water to each plant daily. Example written correctly in 3rd person: 5ml of water was applied to each plant daily. Make sure to use the correct tense. If you are talking about something that has happened in the past, use past tense. Present tense can be used when referring to scientific principle such as "Meiosis involves two divisions." Use APA formatted references and in text citations. Direct quotations should not be used in lab reports. Any information that is not common knowledge needs to be cited. When in doubt, cite it. Failure to cite information can be plagiarism. For more information on what constitutes plagiarism go here. If you need to review APA formatting for references and citations go here and scroll down to the bottom of the page (citation examples section).
