"Into Thin Air" A Case Study in Physiology Part II Gasping for Air by Jennifer Lundmark Department of Biological Sciences Califo

rnia State University, Sacramento John, the assistant expedition leader and a seasoned alpinist, helped Tom guide Mark down the steep trail. Mark's breathing, increasingly labored with every passing moment, was loud enough to worry Emily and Pete, the expedition's final climber. "Geez, do we sound like that?" gasped Pete. "I mean, I'm out of breath, too, but he sounds horrible!" "No, we're not that bad. Remember, that's why we spent the prep month at 15,000 feet. Mark was with us, so he experienced the same physiological changes we did. This," Emily nodded at Mark, "is some sort of problem." Questions: 1. What physiological changes is Emily referring to (above) that will occur when someone lives at altitude for an extended period? 2. How are these changes advantageous?3. What is the specific physiological pathway that results in the changes described?

Answer:

1. The physiological changes that will occur when someone lives at altitude for an extended period include increased production of more red blood cells.

2. The changes are advantageous as the person can survive lower altitude better and strenuous activities that interferes with breathing.

3. The specific physiological pathway that results in the changes described involves decrease in pulmonary ventilation at high altitude leading to hypoxia then hypoxemia. The body then produces more red blood cells to counteract the lower oxygen saturation in blood in high altitudes.

The majority of triglyceride digestion occurs in the small intestine facilitated by the enzyme
bixtya [17]

Answer:

pancreatic lipase

Explanation:

Enzymes from pancreas involved in triacylglycerol digestion are called pancreatic lipases and they catalyze the partial hydrolysis of triglycerides into a mixture of free fatty acids and acylglycerols. After digestion of lipids, monoglycerides and fatty acids associate with bile salts and phopholipids to form micelles. Micelles are structures that are necessary for the transport the poorly soluble monoglycerides and fatty acids to the surface of the enterocyte. But, micelles cannot be absorbed by epithelial cell, only freely dissolved monoglycerides and fatty acids can. Free fatty acids and monogycerids can just diffuse across the plasma membrane because of their nonpolar nature.

 Some absorption (e.g. for cholesterol) may be facilitated by specific transport proteins.
