Question

Statement - I: In P , the outer membrane is porous while the inner membrane is deeply folded which increases the surface area for ATP generation.
Statement - II: Q has connections with the membranes of endoplasmic reticulum and constitute another portion of a complex cellular membrane system.
Select the correct options for P and Q.
$\begin{array}{ccc}& \text{P}& \text{Q}\\ \text{(i)}& \text{Lysosomes}& \text{Golgi apparatus}\\ \text{(ii)}& \text{Mitochondria}& \text{Lysosome}\\ \text{(iii)}& \text{Endoplasmic reticulum}& \text{Mitochondrion}\\ \text{(iv)}& \text{Mitochondria}& \text{Golgi apparatus}\end{array}$

• A. (i)
• B. (ii)
• C. (ii)
• D. (iv)

Answer 1

The correct option is D (iv)

Mitochondrion possesses double membrane as its covering. The outer smooth surface and the inner membrane forms infoldings called as cristae, which increases surface area for more formation of energy in the form of ATP.
The Golgi complex works closely with the rough ER. When a protein is made in the ER, something called a transition vesicle is made. This vesicle or sac floats through the cytoplasm to the Golgi apparatus and is absorbed.
