Respiration

Question 1

Respiratory acidosis

Answer 1

When the lungs cannot remove enough of the CO2 that builds up in the body tissues.

Excess CO2 results in a decrease in blood pH, making the blood more acidic.

Question 2

Respiratory alkalosis

Answer 2

• Blood pH increases (gets more basic), too much O2 in blood
• due to excessive expulsion of CO2 from lungs
• occurs due to hyperventilation

Question 3

Describe Hb

Answer 3

• Hemoglobin is a quaternary protein made of 4 protein chains, 2 alpha and 2 beta
• each protein has a Fe containing heme group at the center. Each can hold one O2 molecule.

Question 4

Describe the Hb binding curve (oxygen pressure vs. % hemoglobin saturation “SO2”)

Answer 4

Sigmoid curve, example of curve in printer paper notes
