Explain How the Structures of Biological Macromolecules Determine Their Properties and Functions

Macromolecules which are both hydrophobic and hydrophilic and are a major component of cell membranes are -

• polysaccharides

• proteins

• phospholipids

• inorganic

Which of the following is not a lipid?

• steroid

• cholesterol

• wax

• cellulose

What monomer is represented by this diagram?

• monosaccharide

• nucleotide

• glycerol

• Amino acid

Which of the following macromolecules are a prominent part of animal connective tissue such as cartilage and keratin?

• carbohydrates

• lipids

• proteins

• nucleic acids

Many land plant store energy in starch. When energy is needed, the starch molecules can be broken down quickly. Starch is which of the following molecules?

• amino acid

• lipid

• polysaccharide

• DNA chain

Beeswax is a waxy substance that is produced by bees and then harvested by humans for a variety of uses. Ancient Romans used beeswax as a waterproofing agent because it is not water-permeable. Beeswax is which of the following types of organic molecule?

• carbohydrate

• lipid

• nucleic acid

• protein

Which of the following macromolecules are a prominent part of animal tissues that function in insulation, helping animals conserve heat?

• carbohydrate

• lipid

• proteins

• nucleic acids

Many plants have waxy coatings on some surfaces. This coating reduces water loss because it is not water-permeable. This waxy coating is which of the following types of organic molecule?

• carbohydrate

• lipid

• nucleic acid

• protein

Many land plants store energy in starch. When energy is needed, the starch molecules can be broken down quickly. This chemical reaction produces which of the following?

• amino acid

• lipids

• monosaccharides

• RNA chains
