What are the two essential nutrients for the functioning of cells?

I - Carbohydrates and lipids are essential nutrients for the functioning of cells.
II - Carbohydrates are molecules formed by carbon, hydrogen, and oxygen atoms, while lipids are formed by the union of fatty acids and a type of alcohol.
III - Triglycerides are lipids formed by fatty acids and glycerol, and are found in the adipose tissue of animals and in the seeds of plants.
IV - Phospholipids are complex lipids formed by fatty acids, glycerol, and the phosphate group, and are present in the structures of the cell membrane.
V - Steroids are lipids formed by fatty acids and cyclic chain alcohols, such as cholesterol, and have metabolic importance in the formation of steroid hormones, vitamin D precursor, and bile components.
