Q. No.Locomotion is a very important feature in animals. Considering the frequent need for locomotion in animals, an animal would obtain the greatest benefit from storing its energy as:
1. proteins
2. minerals
3. carbohydrates
4. fats
Excess carbohydrates and proteins are stored in the body as
(1) amino acids
(2) fats
(3) starch
(4) monosaccharides
