Key concepts
Specialized functions of cellsrespiration,
protein synthesis, mitosis, meiosis Basic
molecules for cell growthsimple sugars, amino
acids, fatty acids. Basic chemicals, molecules
and atomswater, minerals, carbohydrates,
proteins, fats and lipids, nucleic acids carbon,
hydrogen, oxygen, nitrogen. Cells come only from
other cells.

• A protein is
• constructed from amino acids
• building block for animals only
• c. a small molecule
• d. made of carbon, hydrogen and oxygen only

17
a. constructed from amino acids Correct
amino acids are the subunits (monomers) that make
up a protein (polymer). There are 20 different
amino acids that can make thousands of different
proteins, depending on their order and length

• building block for animals only
• Incorrect plants also require proteins
• (they have the ribosomes to manufacture them)

Return to the Question
19
c. a small molecule Incorrect proteins are
polymers, meaning they are large molecules made
from repeating subunits (the amino acids). Many
proteins are made of hundreds of amino acids.

d. made of carbon, hydrogen and oxygen
only Incorrect Although the do contain carbon,
hydrogen and oxygen, all amino acids also contain
Nitrogen. Therefore, all proteins also contain
Nitrogen
