Exploring Organic Macromolecules in Life

What are isomers?

• Compounds that share the same geometric configuration

• Molecules with the same molecular formula but different structural arrangements

• Molecules with different molecular formulas but the same structural arrangement

• Atoms that share the same number of neutrons

What does 'monomer' mean in the context of macromolecules?

• A single unit that combines to form polymers

• A type of polymer

• A reaction that splits water molecules

• A bond between atoms

What is the role of polymers in biology?

• To act as catalysts

• None of the above

• To break down into monomers

• To form tissues and structures

What is the primary function of dehydration synthesis in biological systems?

• To create water from hydrogen and oxygen

• To remove water to join molecules together

• To add water to molecules

• To break down complex molecules into simpler ones

What is the result of a dehydration synthesis reaction?

• Formation of a new water molecule

• Both A and B

• Consumption of a water molecule

• None of the above

What does hydrolysis accomplish in the digestive system?

• It stores energy in chemical bonds

• It synthesizes water molecules

• It breaks down nutrients into simpler forms

• It builds complex nutrients from simpler ones

Which process is used to break down polymers during digestion?

• Condensation

• Photosynthesis

• Hydrolysis

• Dehydration synthesis

Which element is considered the 'backbone of life' due to its versatile bonding properties?

• Oxygen

• Nitrogen

• Hydrogen

• Carbon

What distinguishes an organic molecule?

• Only contains oxygen

• Absence of carbon

• Made up entirely of water

• Presence of carbon and hydrogen

Why is carbon so crucial in organic chemistry?

• It can form up to four bonds

• It only bonds with hydrogen

• It cannot form double bonds

• It is the lightest element
