Understanding Organic Compounds

Why are organic compounds significant in biology?

• They are not found in living organisms.

• They are found in all living things.

• They are only found in plants.

• They are only found in animals.

What makes carbon a unique element in forming bonds?

• It has an atomic number of 12.

• It only bonds with hydrogen.

• It can form strong covalent bonds with many elements.

• It cannot bond with other carbon atoms.

How many valence electrons does a carbon atom have?

• Six

• Four

• Two

• Eight

What is the significance of carbon's ability to form long chains?

• It makes carbon unstable.

• It prevents carbon from bonding with other elements.

• It allows for the creation of diverse organic molecules.

• It limits the diversity of organic molecules.

What are monomers?

• Large molecules made of repeating units.

• Small organic molecules that include carbon.

• Inorganic molecules without carbon.

• Molecules that cannot bond with others.

What is polymerization?

• The process of breaking down polymers.

• The process of creating polymers from monomers.

• The process of forming inorganic compounds.

• The process of forming single atoms.

Which elements are commonly found in organic monomers besides carbon?

• Gold and Silver

• Iron and Copper

• Hydrogen and Oxygen

• Helium and Neon

Which of the following is NOT a type of organic macromolecule?

• Minerals

• Proteins

• Lipids

• Carbohydrates

What is an example of a macromolecule?

• Water

• DNA

• Salt

• Oxygen

What is the role of macromolecules in living organisms?

• They are inorganic molecules with no biological role.

• They are large molecules essential for life processes.

• They are small molecules with limited functions.

• They are only found in non-living things.
