Question

Many biological gases like O; and CO; non-polar, hence, insoluble in aqueous medium. How are they transported within the living matter (cells)? 8. Define the principle (thermodynamic) behind hydrophobic effects in terms of entropy. Give biological examples of common hydrophobic interactions. 9. 13. Which interaction plays role in: In DNA: Base pairing: Base stacking: In proteins helix formation: 14. Explain why the following processes are thermodynamically favorable: in terms of entropy and enthalpy Salt dissolving in water: Micelles formation: Ice melting at room temperature: 15. Describe the structural difference between ice and water which makes ice float on water and also remain liquid even at high pressure (under the sea)

Explanation / Answer

Ans- oxygen and carbon dioxide are transported in living cells by the help of heamoglobin which is present in the blood. The oxygen and carbon dioxide makes compound with the heamoglobin depending upon their partial pressure. In lungs where oxygen partial pressure is great, here heamoglobin left the Co2 and bind to O2. In tissue where Co2 partial pressure is great it left O2 here and bind with Co2. This repetitive cycle facilitate the transport of oxygen in living cells.
