Answers

Fats are the most highly concentrated source of energy in the body, providing around 9 calories per gram. They are stored in the body for times of energy shortage, while proteins, carbohydrates, steroids, and amino acids have other primary functions.

The most highly concentrated source of energy in the body is fats. While all macronutrients - proteins, carbohydrates, and fats - provide energy, fats are the most energy-dense. They provide about 9 calories per gram, compared to 4 calories per gram for both proteins and carbohydrates. This is why fats are often stored in the body for times of energy shortage. Steroids and amino acids, while important for other functions in the body, aren't primary sources of energy.
