Why do you think it is important that biologists have a good understanding of chemistry? Like all matter, living things are made of elements and chemical compounds. In addition, the survival of living things depends on chemical reactions that take place within and outside their bodies. Therefore, to understand living things, biologists needs a good understanding of chemistry. hydrogen bond the weak bond that forms between a hydrogen atom with a partial positive charge an atom with a partial negative charge like oxygen, nitrogen or fluorine.
Biological Importance Of Carbon. Carbon forms the backbone of biology for all of life on Earth. Complex molecules are made up of carbon bonded with other elements, especially oxygen, hydrogen and nitrogen, and carbon is able to bond with all of these because of its four valence electrons. Carbon is abundant on earth. It is also light weight and the atom is relatively small in size, making it easier for enzymes to manipulate carbon molecules.
