Detailed explanation-1: -Hence the hydrogen oxygen ration in carbohydrates is 2:1.

Detailed explanation-2: -The three elements namely carbon, hydrogen, and oxygen present in carbohydrates are in the ratio of 1:2:1 respectively, this is why they are called carbohydrates. 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.

Detailed explanation-3: -Carbohydrates usually have a ratio of two hydrogen for one oxygen (just like water) along with the same number of oxygen atoms and carbon atoms. Many molecules that give energy to living organisms get that energy from some sort of carbohydrate like sugars, starch, or cellulose.

Detailed explanation-4: -The ratio of hydrogen atoms to oxygen atoms used to make water molecules is always 2:1, no matter how many water molecules are being made.
