Question 3 of 5
Partial pressure of O2 in the inspired air is 156 mm Hg and that of CO2 is
Correct Answer: A
Rationale: Step-by-step rationale: 1. Inspired air has O2 partial pressure of 156 mm Hg. 2. In alveoli, O2 is exchanged with CO2. 3. CO2 partial pressure in alveoli is lower than in inspired air. 4. Therefore, CO2 partial pressure in inspired air must be much lower. 5. Choice A (0.3 mm Hg) is the only option significantly lower than O2 pressure, making it the correct answer. Summary: - Choice A is correct as it reflects the lower CO2 partial pressure compared to O2. - Choices B, C, and D are incorrect as they do not show a significant difference in partial pressure compared to O2.
Question 4 of 5
2,3 DPG (Diphospho glycerate) is an important molecule that competes for Oxygen binding sites of Hemoglobin. It is present in
Correct Answer: B
Rationale: The correct answer is B: Erythrocytes. 2,3 DPG is a molecule found inside red blood cells (erythrocytes) that helps in regulating the oxygen binding capacity of hemoglobin. It competes for oxygen binding sites and helps in the release of oxygen to tissues. Choice A (Blood Plasma) is incorrect because 2,3 DPG is not found freely circulating in the blood plasma. Choice C (Leucocytes) is incorrect as 2,3 DPG is not primarily found in white blood cells. Choice D (Blood of lungs) is incorrect as 2,3 DPG is mainly located within red blood cells and not in the blood present in the lungs.
Question 5 of 5
Rectal respiration is seen in
Correct Answer: C
Rationale: Rectal respiration in insects involves the exchange of gases through the anus. The correct answer is C, Niads of Dragonfly, as they have specialized structures called rectal gills for respiration. Cockroach (A), Spider (B), and Water flea (D) do not possess rectal gills or exhibit rectal respiration. Cockroaches have spiracles for respiration, spiders have book lungs or tracheal systems, and water fleas have gills located elsewhere on their bodies. Thus, only Niads of Dragonfly demonstrate rectal respiration, making it the correct choice.
