Match List-I with List-II Choose the correct answer from the options given below.

  1. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
  2. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
  3. (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
  4. (a)-(iii), (b)-(iv), (c)-(ii), (d)-(i)

Answer

(3) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)

Solution

(a) Porins are proteins that form huge pores in the outer membrane of mitochondria (and plastids) ⇒ (iv).

(b) Leghaemoglobin, an oxygen scavenger in root nodules of legumes, gives the nodules their pink colour ⇒ (i).

(c) In the light reaction, H+ (protons) accumulate in the lumen of the thylakoid, creating the proton gradient for ATP synthesis ⇒ (ii).

(d) As per NCERT, the respiratory pathway is involved in both anabolism and catabolism, so it is better considered an amphibolic pathway ⇒ (iii).

∴ (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii).

Answer: (3)
