Question: The molecules of life are all...
Answer: organic compounds
Question: What is an organic compound?
Answer: molecules that are built on a backbone of carbon atoms
Question: Inorganic compunds
Answer: do NOT have carbon in them
Question: Carbon
Answer: a versatile element that forms the "backbone" of many molecules
important for life
Question: Each carbon atom can form ________ with up to FOUR other atoms

Answer: covalent bonds
Question: Functional Groups
Answer: clusters of atoms that are covalently bonded to a carbon backbone;
they give organic compounds their specific properties; a tiny difference in
them can lead to the major impacts of a molecule
Question: Metabolism
Answer: activities by which cells acquire and use energy as they construct,
rearrange, and split organic compounds --> these activities allow cells to stay
alive, grow and reproduce--> requires enzymes
Question: Enzymes
Answer: proteins that cause reactions to occur faster and costing less energy
