Biological Macromules

Question 1

Biological Macromules

Answer 1

A large organic molecule such as carbohydrates, lipids, proteins and nucleic acids.

Question 2

Monomer

Answer 2

A molecule that is a building block for larger molecules (polymers).

i.e. amino acids are building blocks for proteins.

Question 3

Polymer

Answer 3

A large molecule made of repeating subunits (monomers).

i.e. a carbohydrate is a polymer that is made from repeating monosaccharides.

Question 4

Carbohydrates

Answer 4

Building Block: Monosaccharides

Functions: Provides cells with quick short-term energy, scourge of dietary fiber.

Examples: Glucose, sucrose, starch, cellulose, chitin.

Question 5

Lipids

Answer 5

Building Blocks: Fatty acids and glycerol.

Functions: Provide cells with long-term energy, make up biological membranes.

Examples: Fats, phospholipids, waxes, oils, grease, steroids

Question 6

Proteins

Answer 6

Building Blocks: Amino acids.

Functions: Provide cell structure, send chemical signals, speed up chemical reactions, etc.

Examples: Charitan (found in hair and nails), Hormones, enzymes, antibodies.

Question 7

Nucleic Acids

Answer 7

Building Blocks: Nucleotides.

Functions: Store and pass on genetic information.

Examples: DNA, RNA.
