Respiration Lab

Describe the process of external gas exchange. What gases are being changed? Why?
External gas exchange is between the air and lungs. Oxygen goes into the blood from the air via alveoli. Carbon dioxide goes into alveoli into air from blood. You breath out carbon dioxide because of cellular respiration. O2 + glucose → H2O + CO2 + ATP
Procedure:
Observations:
Part A - Aerating of lime water had no changes (left test tube). The test tube that had carbon dioxide aired into by a human turned cloudy ( right test tube).
Part B - The beaker to the left turned into a light green was aerated which means it is neutral. The beaker to the right had distilled water and had a human being breathed carbon dioxide out into it turned into a vibrant yellow which means its highly acidic.
Part C -
Amount of breaths taken in 60 seconds; 28, 25 and 18.
Amount of breaths taken in 30 seconds; 18, 14 10.
The results which were taken in thirty seconds are slightly higher (if multiplied by 2) to equal out the amount of time given to breath. This test was mostly subjected to human error so therefore it is not conclusive.
Questions:
Part A
1. What does a change in color in the lime water indicate?
A change in color indicates chemical change.
2. What is the purpose of the control test tube?
To compare the difference between how the lime water is affected by oxygen and carbon dioxide.
Part B
3. What does the change in color of the universal indicator mean?
When your body breathes out C02 and it combines with H2O, the pH levels change and the H2O becomes acidic.
4. What is the purpose of the control beaker?
The purpose is to compare and see the results of both test tubes
5. Explain what is happening in the test beaker of water.
Both of the beakers remained the same until the universal indicator was added. The beaker that was aerated turned into a light green color, symbolizing that it is neutral. The beaker that we breathed out carbon dioxide into turned yellow, symbolizing it is acidic.
6. Why does your blood not become acidic?
Our blood contains hydrogen with hemoglobin molecules which regulates our pH levels. That keeps are blood from not becoming acidic.
Part C
8. Explain the results for Part C. What happened to the breathing rate? What mechanism is responsible for this change?
I think part C failed due to human error. The participants continuously lost count throughout the course of the test.
Lung Inflation and Deflation Lab
This lab is a way to show the mechanism of breathing. When the diaphragm goes down, the lung inflates. when the diaphragm goes back up, the lung deflates.
Respiratory System - Free Divers Are Immoral
The respiratory system is made up of
several organs and structures, including the lungs, windpipe, diaphragm and
alveoli. It is responsible for taking in oxygen and taking out carbon-dioxide.
The average time an adult can hold their
breath is between 30 and 60 seconds. This set quantity has to do with the
buildup of carbon dioxide than the lack of oxygen, which your body stores in
muscle proteins called myoglobin. But free divers (people who practice the
sport of diving underwater without using equipment like scuba gear) have
different techniques, such as hyperventilation, to decrease the amount of
carbon dioxide in the blood, allowing them to hold their breath for remarkable
long times. An example is Denmark's Stig Severinsen who currently holds the
Guinness World Record for the longest free dive. In 2010, he held his breath
underwater for 22 minutes.

Exercise Science - Fitness Goal
My fitness goal: My fitness goal is to increase my flexibility because I feel as though my body is above average in all six departments we have measured except for flexibility.
How you can measure it (specific fitness test): I scored a 8/17 on the "FitNation Flexibility Test." This scored surprised me because I have been working on my flexibility for quite some time. After doing research, visiting a chiropractor and physiotherapist, I have concluded the fact my body is not flexible what so ever is because of the amount of stress I put on my muscles on a weekly basis. I was recommended to do only a certain amount of training which would allow my body to become less injury prone. My goal is to score a +14 on the next "FitNation Flexibility Test" which will take place near winter break (Every 2-3 months).
A workout / app that will help you meet your goal: After consulting my physiotherapist and chiropractor, they insisted that I began doing "active isolating stretching." AIS is a newly discovered stretching method which makes your body go beyond its stretching limits which allows you to increase your flexibility by %10-%15 if the structure of the stretching routine is correct. I took on the responsibility of trying to find a stretching routine which would give me the success I desired.
I found this amazing routine constructed by The Northern Quarter Clinic on Youtube. I have been doing this routine twice on a daily basis and so far I have seen a huge difference doing it on a consistent basis.

The respiratory system takes the oxygen needed for the body from the out side of the body and brings it into the lungs where it is diffused through the lungs and into the blood stream. The circulatory system carries the oxygenated blood throughout the body where oxygen is exchanged for waste materials, for example, carbon dioxide, which is carried back to the lungs where it is let into the atmosphere (exhalation) in exchange for Oxygen (inhalation). One of the interesting things I've learned from watching the "Crash Course Video" was how animals obtain oxygen by the process called simple diffusion. This process allows animals to inhale oxygen without lungs, the oxygen goes into the animals, passes through wet membranes, and is then processed. Another interesting fact I learned is mammals and birds are warm blooded, they lose calories because their body needs to regulate it's body temperature which requires even more oxygen.
Protein Activity
Polar peptide bonds are found between the amino acids.
2. Why does the secondary structure form (Alpha Helix)?
The secondary structure forms because of the polar peptide bonds.
3. What created the 3rd structure? Why did your protein look different then everyone else's?
The 3rd structure was created by the protein attraction or repelling each other. Mine looked different then everyone else's because I choose different proteins which causes different shapes because some proteins repel and some attract to each other.
4. How was the 4th structure created?
The 4th structure was created by two or more polypeptides which got stuck together because two proteins attracted each other.
5. Would your protein have the same shape if you changed the primary structure? Explain.
No it would not because their would be different proteins which repel or attract each other which would make different shapes.
