Question

1. which of the following is not likely to increase in activity in red blood cells as they travel through pulmonary capillaries in the lungs?

a. proton release from hemoglobin

b. co2 binding to amino acids of hemoglobin

c. bicarbonate movement into the cell

d. carbonic acid conversion to carbon dioxide and water

e. chloride ion movement out of the cell

2. When blood leaves tissues that are more metabolically active when at rest, the saturation of the hemoglobin would be

a. 100%

b. more than 75%

c. 0%

d. exactly 75%

e. less than 75%

3. when the digestive tract receives innervation from the parasympathetic division of the autonomic nervous system, the response to the tract is to

a. increase motility, decrease secretory activity

b. increase motility, increase secretory activity

c. decrease motility, decrease secretory activity

d. decrease motility, increase secretory activity

e. decrease stomach activity and increase intestinal activity

Answer 1

Question no 1)option b is the answer as it is the one that is mostly likely will not occur because in the pulmonary capillary the pco2 is high as campared to the alveoli. So carbon dioxide will only dissociate from the hemoglobin.

Option a is not the answer because proton release from hemoglobin occur usually in the circulation

Option ç is not the answer because during circulation bicarbonate movement into cell takes place

Option d is not the answer because carbon acid conversation to carbon dioxide and water take place in circulation

Option e is not the answer because chloride ion movement out of cell occurs
