Which of the following biological macromolecule is correctly paired with its main function in the body?

Lipids-tores glucose and are the cell's energy reserves

Lipids-growth and repair of cellular structures

Proteins-growth and repair of cellular structures

Proteins-stores glucose and are the cell's energy reserves

Answer is: Proteins-growth and repair of cellular structures.

Proteins are macromolecules made of amino acids (usually 20 amino acids) and they are main structure molecules of all living cells.

Lipids and sugars (glucose) are main source of energy in every living organism and they are used as the cell's energy reserves.
