Nutrients which provide energy include all of the following except:

Question

BlackTom AI · Accepted Answer

When assessing which nutrients provide energy, I start by listing typical energy sources and their roles.
Option 1: carbohydrates. They are a primary energy source, yielding a quick and readily available supply of calories, especially during exercise or high-intensity activities. This option cannot be the exception, so it’s not the correct choice for 'except.'
Option 2: protein. While protein can be used for energy if carbohydrate stores are low, its main function is to provide amino acids for tissue repair and maintenance. This means protein is not primarily an energy nutrient, but it does contribute energy under certain conditions, so it’s not the best answer to the question either.
Option 3: fat. Fat is a dense energy source, supplying a large amount of calories per gram and serving as a major energy reserve, especially during prolonged activities. Because fat clearly provides energy, this option is not the exception.
Option 4: vitamins. Vitamins themselves do not contain calories and do not supply energy. They play crucial roles as cofactors and coenzymes in metabolic pathways that release energy from macronutrients, but they do not provide energy directly. This is the key distinction that makes vitamins the exception among the options.
Thus, none of the energy-providing macronutrients (carbohydrates, protein, fat) fit the criterion of not providing energy, whereas vitamins do not supply energy themselves. Therefore, vitamins are the nutrient type that does not provide energy directly, matching the prompt’s request for the exception.
