Question

Give reason for the following: (a) Inner membrane of mitochondria is deeply folded.
(b) It is difficult to pull out the husk of a coconut.
(c) Making anti-viral medicines is harder than making anti-bacterial medicines.

Answer 1

Answer:

1. To increase the capacity of the mitochondrion to synthesize ATP, the inner membrane is folded to form cristae. These folds allow a much greater amount of electron transport chain enzymes and ATP synthase to be packed into the mitochondrion.
2. Walls of sclerenchyma are lignified, which make them thick. This tissue makes the plant hard and stiff. Coconut husk is very hard and is made of such thickened, lignified cells. Such cells make it very hard to pull out the coconut husk.
3. It is difficult to make antiviral medicines than making antibiotics because viruses have few biochemical mechanisms of their own. They enter the host cells and use their machinery for their life processes. So, antiviral medicines will work against the host body.
