A alternativa correta é a letra B) Statements I and III are correct. A afirmação I está correta, pois o colesterol é um dos esteroides mais importantes produzidos e degradados pelo fígado, que regula a taxa dessa substância no sangue. A afirmação III também está correta, pois o colesterol é um dos esteroides mais importantes e está presente nas membranas das células animais. A afirmação II está incorreta, pois os triglicerídeos liberam uma grande quantidade de energia quando oxidados, em comparação com os carboidratos.
