MACROMOLECULES& ENZYMES
BACKGROUND KNOWLEDGE





Carbohydrates, proteins, lipids, and nucleic acids are macromolecules found in cells
Organic molecules always contain carbon and hydrogen. The chemistry of carbon accounts for
the formation of the very large variety of organic molecules found in living things.
Many molecules of life are macromolecules. Just as atoms can join to form a molecule, molecules
can join to form a macromolecule.
When the same time of molecule, called a monomer, joins repeatedly, the macromolecules is
called a polymer.

ACTIVITY
1. Label the following diagram.
NAME: __________________________________
2. Draw a sketch showing the dehydration synthesis of two glucose molecules to form a
macromolecule. What is this macromolecule called? Draw the hydrolysis of this molecule to form
2 glucose molecules.
3. Draw the hydration synthesis of a fat molecule from 3 fatty acid molecules bonded with one
glycerol molecule. Draw the hydrolysis of a fat molecule.
4. Draw the dehydration synthesis of 2 amino acid molecules to form a dipeptide. Draw the
hydrolysis of the dipeptide.
