Answer 1

Question 22.

Answer- A. More.

Lipids have more energy than carbohydrates of same weight.

Carbohydrate are easy to digest and give energy more rapidly than lipids.  

Lipids are insoluble in water and are source of fuel in our body.

Question 23.

Answer- C. Inner membrane.

The electron transport chain is part of cellular respiration.
