Explanation:
Detailed explanation-1: -Carbohydrates = energy for cells. Carbohydrates are made of carbon (C), hydrogen (H), and oxygen (O), or CHO, in an approximate ratio of 1:2:1.
Detailed explanation-2: -Carbohydrates can be represented by the formula (CH2O)n, where n is the number of carbon atoms in the molecule. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules.
Detailed explanation-3: -Monosaccharides have carbon, hydrogen, and oxygen in a 1:2:1 ratio. Monosaccharides or simple sugars include glucose, galactose, and fructose.
Detailed explanation-4: -In lipids, the components are the same but the ratio is less for oxygen, so it is 1:2: less than one for C:H:O.
