Lesson Essential Questions
 How do the unique molecular and chemical properties
of water enable the molecule to support life on earth?
 How does the tetrahedral atomic shape of carbon
enable the element to be the backbone of
biomolecules?
 How are carbohydrates, proteins, lipids and nucleic
acids synthesized?
 How do environmental factors affect the synthesis of
biomolecules?
 What are the classes of biomolecules and how do their
structures relate to their functions within an organism?
 How do enzymes affect chemical reactions within all
levels of organization and how do environmental
factors affect their function?

Cells function as microscopic chemical factories
synthesizing and degrading biological molecules
necessary for life.
Liquid water forms hydrogen bonds, is a solvent, and
forms hydronium ions allowing a wide range of
biochemical reactions to occur.
Biological molecules produced by a cell can be used by
the cell or transported outside for use by other cells.
Cells are composed mostly of: C, H, N, O, P, and S.
Carbon rings and chains form the backbone of all
biological molecules.
Many biological molecules are polymers made from
monomers that contain carbon chemically bound with
other elements.
Carbohydrates, lipids, proteins, and nucleic acids are the
chemical foundations for life.
Molecular structure is related to function.
