Biophysical Evaluation Lab Essay

When the pH is not at its optimum, the differing pH's will disrupt the bonding between the R groups of the amino acid causing its structure and the shape of the activation site to change

The protein molecules in many foods provide the amino acid building blocks required by our own cells to produce new proteins. To determine whether a sample contains protein, a reagent called Biuret solution is used. Biuret solution contains copper ions. However, the chemical state of the copper ions in Biuret solution causes them to form a chemical complex with the peptide bonds between amino acids (when present), changing the color of the solution. Biuret solution is normally blue, but changes to pink when short peptides are present and to violet when long polypeptides are present.

Please answer these questions then place them in the drop box for this lab. Use Microsoft word if possible.

The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel, which leaves a clean test tube. Incomplete combustion is the reaction of an element or compound with oxygen to produce some oxides with less oxygen than the most common oxides. Incomplete combustion occurs when there is not enough oxygen to react

3. Experiment: Use the Gizmo to find the carrying capacity with Ample, Moderate, and Little land. List the carrying capacities below.

1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points)

Cellular respiration: C6H12O6  +  6O2 →  6CO2  +  6 H2O  +  36 or 38 ATP

1) Make a graph of resting heart rates from Activity 1. Provide a physiological explanation for fluctuations in resting heart rate over time. Discuss a couple of extrinsic factors that influence the autonomic nervous regulation of resting heart rate.

1.What are some of the advantages and disadvantages of the current health care system in the United States?

We need to know the normal range of movement of the muscles and joints so when moving, handling and positioning a person we know the limits of each limb. We need to take into consideration other factors that may inhibit a person’s movements as:

groups. It was conducted to further the research in choice overload and paralysis of the mind.

Table 1 Concentration of protein, DNA, and ratio of the two in heart, kidney and liver of bos taurus. Average standard deviation of protein concentration is also shown.

Hydrolysis of starch for fungal amylase Aspergillus Oryzae and bacterial amylase Bacillus Licheniformis at different temperatures.

The purpose of the “chi-square test” was to see if our data was in an acceptable range of a specific ratio listed above. The chi-square test took into account the expected deviations in the F2 offspring’s alleles.

For shoulder flexion 61% of the variance could be accounted for by the sit-and-reach. A correlation was also found between the modified sit-and-reach test and both the shoulder extension and hip flexion tests. For shoulder extension 33% of the variance was accounted for by the modified sit-and-reach and for hip flexion 22% of the variance was accounted for by the modified sit-and-reach.
