What is a macromolecule? - CORRECT ANSWER - a molecule containing a very large
number of atoms, such as a protein, nucleic acid, or synthetic polymer.
What is a monomer - CORRECT ANSWER - a molecule that can be bonded to other
identical molecules to form a polymer.
What is a polymer? - CORRECT ANSWER - long chain of monomers
What is a carbohydrate? - CORRECT ANSWER - compound made up of carbon,
hydrogen, and oxygen atoms; major source of energy for the human body. MADE OF

What is a lipid? - CORRECT ANSWER - fats and oils. soluble in non-polar
what is a protein - CORRECT ANSWER - chain of amino acids linked by peptide bonds.
order o amino acids determines shape & function
what is a nucleic acid? - CORRECT ANSWER - information storage and expressions.
chains o nucleotides including a base, sugar, and phosphate group
what is a condensation reaction - CORRECT ANSWER - When two monomers bond
forming a polymer, and produce a water molecule
what is hyrdolysis - CORRECT ANSWER - when water is added and breaks apart a
polymer
, What is an ampipathic molecule? - CORRECT ANSWER - A molecule with both
hydrophobic and hydrophilic regions.
Why are carbon and water essential to all life? - CORRECT ANSWER - all bodily
reactions involve water and carbon
