Which reason best explains why carbon is able to form macromolecules? carbon is a very large element. carbon can bond with many elements. carbon is found in all living things. carbon can only bond with itself.

Life is based on carbon; organic chemistry studies compounds in which carbon is a central element. The properties of carbon make it the backbone of the organic molecules which form living matter. Carbon is a such a versatile element because it can form four covalent bonds.

hope this helps!

Carbon can bond with many elements.

Explanation:

Macromolecule is a large molecules which is composed of large number of atoms. For example, proteins, carbohydrates, lipids, fats and others. Carbon is able to form macromolecules because it can form bond with many other elements.

Lipids, carbohydrates, proteins and nucleic acids all contain carbon as ingredient. To make up lipids and carbohydrates carbon forms bonds with elements such as oxygen and hydrogen. For proteins the carbon forms bond with oxygen, hydrogen and nitrogen (sometimes sulphur). For nucleic acids, it forms bond with oxygen, hydrogen, phosphorus and nitrogen.
