LSU BIOL 1001 Chapter 3 Vocabulary
2026 Expert Verified | Ace the Test
organic - 🧠 ANSWER ✔✔Describing a molecule that contains both carbon
and hydrogen.
inorganic - 🧠 ANSWER ✔✔Describing any molecule not contain both
carbon and hydrogen.
biological molecules - 🧠 ANSWER ✔✔All molecules produced by living
things.
functional group - 🧠 ANSWER ✔✔One of several groups of atoms
commonly found in an organic molecule, including hydrogen, hydroxyl,
, amino, carboxyl, and phosphate groups, that determine the characteristics
and chemical reactivity of the molecule.
monomers - 🧠 ANSWER ✔✔A small organic molecule, several of which
may be bonded together to form a chain called a polymer.
polymer - 🧠 ANSWER ✔✔A molecule composed of three or more (perhaps
thousands) smaller subunits called monomers, which may be identical (for
example, the glucose monomers of starch) or different (for example, the
amino acids of a protein).
dehydration synthesis - 🧠 ANSWER ✔✔A chemical reaction in which two
molecules are joined by a covalent bond with the simultaneous removal of
a hydrogen from one molecule and a hydroxyl group from the other,
forming water; the reverse of hydrolysis.
hydrolysis - 🧠 ANSWER ✔✔The chemical reaction that breaks a covalent
bond by means of the addition of hydrogen to the atom on one side of the
original bond and a hydroxyl group to the atom on the other side; the
reverse of dehydration synthesis.
