`CO_(2)` dissocated from carbamino haemoglobin when

A

`pCO_(2)` is high and `pO_(2)` Is low

B

`pO_(2)` is high and `pCO_(2)` IS low

C

`pCO_(2)" and "pO_(2)` are equal

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
b
When, the `pCO_(2)` is low and `pO_(2)` is high as in the lung aiveoii, dissociation of `CO_(2)` from carbamino-haemoglobin takes place, `CO_(2)` which is bound to haemoglobin from the tissue is delivered at the alveoli, to maintain the concentration of `CO_(2)` thus increasing `pCO_(2)`.
Exchange of gases takes place between tissue captiiary and tissue cells. Capillary can. with high `pO_(2)` causes diffusion of `O_(2)` into tissue cells via tissue fluid on the other hand high `pCO_(2)` in the tissue cells causes diffusion of `C_(O)`, Into tissue capiuary via tissue fluid.

CO_2 dissociates from carbaminohaemoglobin in the alveoli when

Dissociation of CO_(2) from carbamino-haemoglobin takes place when:

O_(2) dissocation curve is

Read the following statement . a) High H^+ concentration and higher temperature are favourable for dissociation of oxygen from oxyhaemoglobin. b) Partial pressure of oxygen in alveoli is higher than in tissue . c) The maximum volume of air a person can breather in after a forced expiration is vital capacity. d) In alveoli PCO_2 low and PO_2 high are for dissociation of CO_2 from carbamino haemoglobin . How many of the above statement are true ?

[A] : Role of RBC' In CO_2 transport Is primarily to form HCO_3 - for carriage in plasma and re- convert them to CO_2 . [R]: About 42% CO_2 is carried in the form of carbamino haemoglzobin which breaks down «in the lungs to release O_2 again

Assertion :- In the alveoli, dissociation of CO_(2) from carbamino-haemoglobin takes place Reason :- In the alveoli P_(CO_(2)) is low and P_(O_(2)) is high.

What is the shape of O_(2) dissociation curve for haemoglobin ?
