Which nutrient provides the maximum energy on breakdown?

Correct option is B

The correct answer is (b) Fats.
· Fats provide the maximum energy on breakdown. When metabolized, fats yield about 9 calories of energy per gram, which is more than double the energy provided by carbohydrates and proteins, both of which provide about 4 calories per gram.
· Fats are stored in the body as a long-term energy reserve and are broken down into fatty acids and glycerol during metabolism, releasing a large amount of energy.
Information Booster:
Carbohydrates:
· Provide 4 calories per gram and are the body's primary source of quick energy, especially in the form of glucose.
Fibres:
· Indigestible components of plant-based foods; they do not provide energy but are important for digestive health.
Proteins:
· Provide 4 calories per gram and are mainly used for building and repairing tissues, though they can also be used as an energy source when necessary.
