Biology - chapter 5

This macromolecule plays an important role in the structure and function of the cell membrane.

• proteins

• nucleic acids

• lipids

• carbohydrates

The bond that joins amino acids are called:

• Peptide Bonds
• Ester Bonds
• Glycosidic Linkages
• Phosphodiester Bonds

Amino acids all have the same general structure except for the:

• Amino Group
• Carboxyl Group
• 'R' Group
• Carbonyl Group

The monomers of proteins are

• nucleotides

• amino acids

• monosaccharides

• fatty acids

What kind of reaction is shown here?

• dehydration synthesis
• hydrolysis

Which describes the functions of proteins in living things?

• structural, transport, signaling, catalysts, etc.

• stores and transmits genetic information

• stores energy and makes up cell membranes

• quick energy and forming cell structure

All proteins

• have a unique structure that determines their unique function.

• are exactly the same in function but different in structure.

• are exactly the same in structure but different in function.

• are enzymes.

This is one job proteins do NOT have in the body

• storing genetic information
• structure
• speed up chemical reactions
• transport things through cell membrane

A biological polymer that stores and transmits genetic information is a ...

• nucleic acid
• carbohydrate
• lipid
• protein

Which polymer group is used as long term STORED energy?

• carbohydrate
• lipid
• protein
• nucleic acids
