Monomers are the ​ (a)   , or small molecules & atoms, that bond together to form more complex structures such as polymers.

The monomer of carbohydrates is the ​ (b)   .

Most ​ (c)   are built of glycerol & fatty acids.

Proteins consist of many ​ (d)   bonded together.

The building block of a nucleic acid is called a ​ (e)   .

• building blocks
• monosaccharide
• lipids
• amino acids
• nucleotide

​ (a)   are large molecules made up of many repeating smaller molecules called monomers.

When many monosaccharides are joined together, it forms a​ ​​ (b)   .

Most lipids are built of ​ (c)   .

​ (d)   are made up of long chains of amino acids linked together by peptide bonds, forming what is called a polypeptide chain.

​ (e)   , such as DNA and RNA, are composed of long chains of repeating nucleotide units, each containing a sugar, phosphate group, and nitrogenous base.

• Polymers
• polysaccharide
• glycerol & fatty acids
• Proteins
• Nucleic acids

Why are carbohydrates important to living things?

[check all that apply]

• Plants have cell walls of carbohydrates (cellulose) that provide structural support and protection.

• Fungi have cell walls of carbohydrates (chitin) that provide structural support and protection.

• The carbohydrate glucose is used to make ATP in cellular respiration, a fast source of energy.

• Starch is a complex carbohydrate, or polysaccharide, that provides stored energy.

• Glycogen is a complex carbohydrate molecule that serves as the primary energy storage form of glucose (sugar) in animal cells.

What are the functions of lipids, that are important to living things?

[check all that apply]

• Lipids make up the phospholipid bi-layer of the cell membrane.

• Lipids are a source of long-term energy storage that regulate temperature to conserve heat.

• Many lipids act as hormones and are part of the nervous system.

• Lipids are a form of starch that provides stored energy to plants.

• Lipids contain genetic information and are found in the DNA of organisms.

What are the functions of proteins, that are important to living things?

[check all that apply]

• Proteins are embedded in cell membranes as protein channels that help selectively transport of molecules

• Proteins make up collagen and helps build & repair muscle tissue, bones and hair.

• Enzymes are proteins that function as biological catalysts to speed up chemical reactions within the body.

• • Antibodies, essential components of the immune system, are made up of proteins. They help fight infections and protect the body from diseases. 

• Proteins contain genetic information and are found in the DNA of organisms.

Why are nucleic acids important to living things?

[check all that apply]

• All life such as plants, animals, fungi, bacteria, contain nucleic acids

• Nucleic acids make up collagen and helps build & repair muscle tissue, bones and hair.

• Enzymes contain nucleic acids that function as biological catalysts to speed up chemical reactions within the body.

• All cells contain genetic information in the form of nucleic acids (DNA & RNA) needed for the coding of traits.

Use your 'Burger' notes to complete the following:

DEHYDRATION SYNTHESIS is chemical reaction where two smaller molecules ​ (a)   a larger molecule by ​ (b)   a water molecule. This causes the monomers to bond together.

HYDROLYSIS is a chemical reaction where a water molecule is ​ (c)   to ​ (d)   a larger molecule into smaller components. This causes the polymer to separate.
