Bios 240 Fall 2017 Exam 2 Name: 100 80 60 S S 40 20 0 without CO2 in the blood CO2 in the blood 0 5 10 15 Partial pressure of oxygen/kPa 31). The figure above describes which of the following? a. the Bohr effect b. a competitive inhibitorX c. performance of an enzyme at two different temperatures d. oxygen transport in the bloodstreamx e. none of the above. 32) Where would you expect to see a foramen ovale? a. In the heart of an alligator b) In the heart of a bird In the heart of an adult human d. In the heart of a fetal human e. All of the above 33. Why is there a sudden drop in blood pressure associated with human capillary beds? a. An increase in the sum of the radi in this region A dramatic decrease in blood viscosity c. The negative pressure associated with venous blood flow d. localized vasodilation e. none of the above

Explanation / Answer

Ans 31:- (a) The Bohr effect.

Explaination:- as the carbon diaoxide increases in the blood it decreases the pH and hence the affinity towards the oxygen by heamoglobin decreases this effect is called as Bohr effect. same is given in the above figure thus the right option is (a)

Ans 32:- (d) in the heart of a fetal human

Explaination:- foramen ovale is a small hole present in the septum in the upper chambers of the heart as before the birth fetus is not able to get oxygen from blood but it gets oxygenated blood from mother and foramen ovale helps the blood to go from veins to right side of the fetus heart and then directly to the left side of heart, then foramen ovale is closed after birth and hence is not present in adult male thus the correct option is (d)
