Haemoglobin binds oxygen reversibly: Hb + O₂ ⇌ HbO₂. How does this equilibrium help deliver oxygen to tissues?
AHigh O₂ in tissues shifts it to the left, absorbing oxygen
BLow O₂ in tissues shifts it to the left, releasing oxygen
CLow O₂ in tissues shifts it to the right, releasing oxygen
DThe equilibrium does not change anywhere in the body

答案: C · 3/4
为什么是这个答案

答案
C · 3/4
17.护理入学考试化学
答案: C · 氧对共用电子的吸引更强,且分子是弯曲形的
为什么是这个答案
O–H 键是极性的,因为氧的电负性更大。弯曲的形状使键偶极矩不能抵消,所以氧略带负电,氢略带正电。
答案
C · 氧对共用电子的吸引更强,且分子是弯曲形的
18.护理入学考试化学
答案: B · Low O₂ in tissues shifts it to the left, releasing oxygen
为什么是这个答案
In the lungs, high O₂ pushes the equilibrium right, loading haemoglobin. In active tissues O₂ is low, so the equilibrium shifts left and HbO₂ releases its oxygen.
答案
B · Low O₂ in tissues shifts it to the left, releasing oxygen
