9A. Proteins and carbohydrates have many functions in the body of an organism. Specific proteins and carbohydrates perform specific tasks. Information about a protein and a carbohydrate is given below. How are ferritin and glycogen similar in their primary functions 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.

9A.  Which of the following biomolecules typically contain both nitrogen and phosphate?

• Lipid
• Protein
  pro
• Nucleic acid
• Carbohydrate

9A.  The differences between two molecules include the type of sugar that forms a section of the molecules and the identity of one of the four nitrogenous bases that make up another section of the molecules.  These two molecules are -

• proteins
• lipids
• nucleic acids
• complex carbohydrates

9A.  Which of the following biomolecules typically contain both nitrogen and phosphate?

• Lipid
• Protein
  pro
• Nucleic acid
• Carbohydrate

9A. Four different nucleotides are used as building blocks of DNA. Which of the following can be used to distinguish one nucleotide from another?

• The nitrogenous base
• The shape of the deoxyribose sugar
• The length of the phosphate group
• The type of fatty acid

9A. The complex carbohydrates pictured below are made by linking molecules of glucose. 
In all three complex carbohydrates, the subunits of glucose are bonded together differently. Because they have different structures, they most likely-

• contain different chemical elements
• form different proteins
• carry different nucleotides
• perform different functions
