Biology

Carbon must perform ? bonds to complete its outer energy level.

4 covalent bonds

polymer

a chemical compound in which each molecule is made up of two or more simpler molecules strung together.

lipid

a group of organic compounds including fats, steroids, and phospholids

protein

a large complex organic molecule consiting of a large number of amino acids linked together by peptide bonds

polymerization

a reaction in which two or more molecules unite, forming a more complex molecule.

nucleic acid

a sequence of sugars, phosphates, and nitrogenous organic bases: DNA and RNA

carbohydrate

a sugar or polymer of sugar; contains the elements carbon, hydrogen, and oxygen

The four major divisions of biological organic substances are

carbohydrates, lipids, proteins, and nucleic acids

Large organic molecules which are synthesized from multiple identical subunits are:

carbohydrates, polymers, proteins, nucleic acids

carbon bonds are almost entirely...

covalent

What happens when organic molecules decompose?

energy is released

The most common elements that bond with carbon are:

hydrogen, oxygen, and nitrogen

The four organic molecules common to organisms are:

proteins, fats, nucleic acids, carbohydrates
