Question

Match the Column I and II

Column (I)	Column (II)
i.	\(\mathrm{CO}_2\) dissolved in plasma	a.	23 %
ii.	\(\mathrm{CO}_2\) transported as bicarbonate ions	b.	7 %
iii.	\(\mathrm{CO}_2\) transported by RBC as carbaminohaemoglobin	c.	70 %
iv.	\(\mathrm{O}_2\) transportation by RBCs as oxyhaemoglobin	d.	97 %

Choose the correct option:

• A. i - b, ii - c, iii - d, iv - a
• B. i - b, ii - a, iii - c, iv - d
• C. i-c, ii-d, iii-a, iv-b
• D. i - b, ii - c, iii - a, iv - d

Hint:

Dissolved CO2 is 7 percent, bicarbonate 70 percent, carbamino compounds 23 percent and oxyhaemoglobin carries 97 percent of O2.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Gases are carried in blood in more than one form.

Step 2: \(\text{CO}_2\)
Dissolved in plasma about 7 \(\%\) (i-b). As bicarbonate about 70 \(\%\) (ii-c). As carbaminohaemoglobin about 23 \(\%\) (iii-a).

Step 3: \(\text{O}_2\)
About 97 \(\%\) of oxygen is carried as oxyhaemoglobin (iv-d).

Step 4: Compare the options
The pairs are i-b, ii-c, iii-a, iv-d.

Final Answer:
The correct matching is i-b, ii-c, iii-a, iv-d. \[ \boxed{\text{(D) }\text{i - b, ii - c, iii - a, iv - d}} \]
