I need to know the hypothesized enzyme
worty [1.4K]

Answer:

Hypotheis:

<em>If high amounts of product in the samples, '+++' , correlates with optimal temperatures and pH for enzyme activity, then...</em>

  • <u>A- Pepsin</u>
  • <u>B- Amylase </u>
  • <u> C- thermophilic enzyme</u>

Explanation:

Enzymes are specialized proteins that function as biological catalysts- <u>they speed up chemical reactions.</u> As proteins, these are susceptible to changes in temperature and pH- they function best at optimal values for both conditions, but can be denatured, rendering them inactive at relative extremes.

Each enzyme provided has its own optimal temperature and pH values.

  • Thermophilic enzymes are usually found in regions characterized by high temperatures. They show high thermostability, and do not become denatured at high temperatures- they thrive, and do not function well at lower temperatures.
  • Amylase is a hydrolase digestive enzyme found in the mouth, that acts on polysaccharides like starch to break 1,4  glycosidic bonds between glucose molecules. It works best at a physiological (neutral) pH and temperatures (around 37°)
  • Pepsin, another digestive enzyme, is a peptidase that breaks down proteins into peptide molecules. It is found in the stomach lining, where the pH  is typically low i.e. acidic due to the hydrochloric acid in digestive juices.

Thus from the table A- pepsin, B- Amylase and C- thermophilic enzyme can be hypothesized.

Beginning with the Superior Vena Cava (SVC) & Inferior Vena Cava (IVC) and ending with the aorta, explain the path that blood takes through the heart and lungs before returning to the body.

The Blood leaves the heart through the pulmonic and into the pulmonary artery and then to the lungs. Blood also leaves the heart through the aortic valve, into the aorta and to the body. This process results in blood flowing through the heart,lungs and body...

Fact if the circulatory or respiratory system were to fail, the other would fail as well, leading to death without medical intervention.  Explain why failure of the circulatory system would cause failure of the respiratory system & Explain why failure of the respiratory system would cause failure of the circulatory system.

Failure of the respiratory system would cause failure of the circulatory system because the respiratory system helps you breath and with you not breathing it would cause the circulatory system to fail because the breathing makes the blood flow through the circulatory system.
