Why are fats useful and sometimes better than carbohydrates

Fats contain more than twice chemical energy as proteins and carbohydrates have. So sometimes fats are very important than carbohydrates or some other biomolecules.

As compared to carbohydrate and proteins fats has more than twice a calories per gram. A gram of fats has 9 calories. A gram of carbohydrate and proteins has about 4 calorie. Therefore,fats useful and sometimes better than carbohydrates.

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
