Bio 1500 Unit 4
1. Bar headed geese migration pattern: Flies from Mongolia to India OVER Himalayas, not around,
at 5800-6400m
2. Composition of atmosphere: 78% N2, 21% O2, 0.04% CO2
3. Portion of each gas in the atmosphere: 78 kPa N2, 21 kPaO2, 0.04 kPa CO2
4. Mount Everest elevation and death zone: Elevation: 8848m
Death zone: 8000m+
5. Top of Mt Everest pressure and portions of each gas: Pressure around 33.7kPa
26 kPa N2, 7 kPa O2, 0.02kPa CO2
6. Organs in mammal lung: lung, trachea, bronchi, bronchioles, alveolar ducts, alveoli
7. inhalation in mammal lung: diaphragm and rib cage muscles contract, expands thorax and lungs and
sucks in air
8. exhalation in mammal lung: diaphragm and rib cage muscles relax
-At rest: elasticity of tissues contracts thorax and presses air out of lungs
1/2
, -heavy breathing: abdominal muscles contract and presses more air out of lungs
9. Gas exchange in lung: alveoli creates close contact of air and blood, diffusion moves O2 and CO2 from
high to low concentrations, and O2 binds hemoglobin in red blood cells
10. Breathing patterns in mammals: -breathing at rest: 2.5-3L
-air exchange at rest: 0.5L
-max air exchange: 3-4.5L
-residual volume: 1-1.5L
-total lung capacity: 5-6L
Gas portions in lung: 13 kPa PO2, 5kPa CO2
11. Difference of PO2 and PCO2 in lungs vs. atmosphere: Lower PO2 in lungs
Much higher PCO2 in lungs
12. Amino acid backbone:: same in all amino acids
13. Amino acid R group: side chain, symbol representing variable part of the molecule
14. Primary protein structure: amino acid sequence
15. Secondary protein structure: hydrogen bonds between backbones of nearby amino acids cause
2/2
