Biology Ch. 2 Section 3

Front 1

Carbohydrates

Back 1

~ are organic compounds made of carbon, hydrogen, and oxygen atoms.

~ are the key source of energy, and are found in most foods. (Especially fruits, grains, and vegetables)

~ Monomer: Monosaccharides

~ Polymer: polysaccharides

Front 2

Monosaccharides

Back 2

~are the building blocks of carbohydrates which are single sugars such as glucose and fructose.

~are major source of energy in cells.

Front 3

Lipids

Back 3

~ Fats are non-polar molecules that are not soluble or mostly insoluble in water.

~Long-term energy storage

~monomer: fatty acids and glycerol

~polymer: Unsaturated fats, saturated fats, and transfat.

Front 4

Proteins

Back 4

~ is usually a large molecule formed by linked smaller molecules called amino acids.

~ Forms muscles, bones, hair, etc.

~Monomer: amino acids

Front 5

Nucleic Acid

Back 5

~ is a long chain of smaller molecules called nucleotides.

~ Code for proteins

~Monomers: nucleotides

~polymers: RNA, DNA, and ATP

Front 6

Amino Acids

Back 6

~are the building blocks of proteins.

Front 7

Nucleotide

Back 7

~ has three parts: a sugar, a base, and a phosphate group, which contains phosphorus and oxygen atoms.

Front 8

ATP

Back 8

~helps manufacture proteins, and is good for energy storage.
