Carbohydrates are nutrients that supply the main energy source for the body, in the form of sugars. t f

False.

Explanation:

Human body derives most of its energy from dietary fat.

Dietary fat is fat consumed in the food that we eat. Fat is a major source of energy in the diet and it provides nine calories per gram and it’s more than twice the number that carbohydrates or protein provide. Dietary fat is different than body fat. Pure carbs give a respiratory quotient of 1, while fat give 0.7. People that are on average diets have a respiratory quotient of 0.8. That indicates that fat is every organism's main fuel. If some is well trained, athletically, more fat and ketones will be used as fuel.

Carbohydrates are nutrients that supply the main energy source for the body, in the form of sugars. This statement is true.

Further Explanation:

Macronutrients are those substances that are needed or required in large quantities. These are essential molecules in food that all individuals need to produce energy, growth, and development. Carbohydrate is an example of an essential macronutrient and they are the main fuel source

It is a major source of energy production or cellularrespiration due to which it is required in large quantities. In the case of exercise, the body requires more energy than a person at rest. The excess requirement of energy is utilized by carbohydrates, followed by fats and proteins. Carbohydrates are the dietary source of energy. These are the polymers of sugars like glucose, fructose, and galactose. These monomer units are attached via glycosidic linkage. These bonds release a higher amount of energy when broken making it available for utilization.
