Final answer:
The statement is true; carbohydrates and lipids are key macronutrients that provide the body with energy. Carbohydrates are used for immediate energy, while lipids offer a dense energy source and play additional roles in biological functions.
Step-by-step explanation:
The statement that carbs and lipids are the macro-nutrients primarily used to provide the body with energy is True. Carbohydrates and lipids are indeed essential macronutrients that are responsible for supplying the body with energy. Carbohydrates, like glucose, are used for immediate energy needs, while lipids, such as fats and oils, provide a concentrated source of energy, with one gram of lipids yielding more than twice the energy of carbohydrates. Lipids also play critical roles in other biological functions, such as forming cell membranes and serving as insulation for vital organs.
Our bodies break down these nutrients during digestion into molecules small enough to be absorbed and converted into ATP, which is the energy currency of our cells. While proteins are also a macronutrient, their primary role is to supply amino acids for building and repairing tissues rather than serving as a primary energy source.
