Answer 1

CO2

Question 2

Answer 2

215ml/min CO2 / 250ml/min O2 = 0.86

Question 3

What is the calculation for oxygen consumed?

Answer 3

O2 air (atmosphere) minus O2 air breathed out is the oxygen you consume.

Question 4

Answer 6

Liver first deaminates the amino acid molecule. Then excretes nitrogen and sulfur in urine and sweat and feces. The remaining keto acid oxidizes to carbon dioxide and water to provide energy for biologic work.

Question 7

What can the RQ-KCal relationship serve to do?

Answer 7

determine energy expenditure during exercise.

Question 8

What is the respiratory exchange ratio?

Answer 8

Reflects the pulmonary exchange of carbon dioxide and oxygen under different physiologic and metabolic conditions

Question 9

Is the R ratio 100% in measuring gas exchange?

Answer 9

It does not fully mirror the gas exchange of the macronutrient mixture catabolized.

Question 10

What is the difference between RER and RQ?

Answer 10

RQ = represents metabolism from all cells in the body. 
RER = Can produce CO2 gased and have a higher CO2 than what metabolism (RQ) is showing us.

Question 11

How to increase CO2 production (expire more CO2 into air)?

Answer 11

Hyperventilation (anxiety)

Question 12

What is the RQ for someone who is hyperventilating?

Answer 12

above 1

Question 13

If the RQ is above 1, what is it considered?
