Biomolecules (midterm review)

What elements make up a nucleic acid?

• CHO

• CHONP

• CHON

• CSHON

Protein and carbs have many functions in the body of organisms. How are they similar for an organism?

• Both store materials needed by the organism

• Both store energy used by the organism

• Both support the structure of the organism

• Both store information for the organism

Carbohydrates have different structures (the way they are shaped/bonded together). Because they have different structures, they most likely ___

• Contain different elements

• Form different proteins

• Carry different nucleotides

• Perform different functions

Birds secrete waxy organic substances to coat their feathers. This wax repels water. This waxy substance is most likely composed of

• Lipids

• Protein

• Carbohydrates

• Nucleic Acids

Which biomolecule is correctly paired with one of its functions?

• Nucleic Acids : digest dead cells

• Lipids : Give quick energy to cells

• Carbohydrates : Store genetic information

• Proteins : Provide structure in skin, hair, nails
