Chapter 48, Problem 1TY

Summary Introduction

Introduction: The exchange of oxygen and carbon dioxide in water or on land requires respiratory organs that are appropriate for the challenges presented by different environmental conditions. Insects use tracheal systems to exchange gases with the air.

Expert Solution & Answer

Answer to Problem 1TY

Correct answer: The partial pressure of oxygen provides the driving force for the diffusion of oxygen across the surface of respiratory organs and in the blood. Hence, the correct answer is option a.

Explanation of Solution

Reason for correct answer:

All gases diffuse from the regions of high pressure to the regions of low pressure. This movement of gases along the pressure gradients is similar to the diffusion of dissolved solutes from the regions of high concentration to low concentration.

Option a. is given as “difference in the partial pressure of oxygen (Po₂) in the environment and in the blood”.

The difference in the partial pressure of oxygen in the air and the blood forms a pressure gradient. This gradient is responsible for the movement of oxygen across the cells of a respiratory organ. Hence, the correct answer is option a.

Reasons for the incorrect answer:

Option b. is given as, “humidity”.

Humidity has an impact on the movement of gases across the cells of a respiratory organ. However, it does not act as a driving force for diffusion of gases. Hence, option b. is incorrect.

Option c. is given as, “partial pressure of carbon dioxide (Pco₂) in the blood”.

The partial pressure of carbon dioxide in the blood plays an indirect role in the movement of gases across the surface of a respiratory organ. Hence, option c. is incorrect.

Option d. is given as, “air temperature”.

The air temperature is one of the factors that decide the rate of diffusion of gases across the cells of a respiratory organ. However, it does not act as driving force for the movement of oxygen across the surface of the respiratory organ. Hence, option d. is incorrect.

Option e. is given as, “Pco₂ in the atmosphere”.

The partial pressure of carbon dioxide in the atmosphere and the body plays an important role in the movement of carbon dioxide across the cells of a respiratory organ. Hence, option e. is incorrect.

Hence, the options b., c., d. and e. are incorrect.

Conclusion

The difference in the partial pressure of oxygen in the environment and the blood acts as a driving force for the movement of oxygen across the cells of a respiratory organ.
