Question

In the tissues, the factors favourable for the dissociation of $O_2$ from oxyhaemoglobin are

$a.$ Low $p{O}_2$​

$b.$ High $p{O}_2$​

$c.$ Low $pC{O}_2$​

$d.$ High $pC{O}_2$​

$e.$ Lower temperature

$f.$ Higher temperature

$g.$ Low $pH$

$h.$ High $pH$

• A. $b,c,e,h$
• B. $a,d,f,g$
• C. $a,d,f,h$
• D. $b,c,e,g$

Answer 1

The correct option is B $a,d,f,g$

Dissociation of $O_2$ from oxyhaemoglobin in tissues

At the site of tissues, the partial pressure of oxygen is less than that of $C{O}_2$ and it is unfavourable for the formation of oxyhaemoglobin.

Also the tissues have high $H^{+}$ concentration and higher temperature that causes the dissociation of oxygen from oxyhaemoglobin.

​​​​​​Final Answer:

$\left(C\right)a,d,f,g$
