Zoology Chapter 2

Front 1

Carbohydrate

Back 1

Composed of Carbon, Hydrogen, and Oxygen.
H-C-OH

Front 2

Glucose

Back 2

The most important energy storing carbohydrate

Front 3

Examples of Carbohydrates

Back 3

Sugar, Starches, and Cellulose

Front 4

Three groups of Carbohydrates

Back 4

Monosaccharides (Simple sugars), Disacchrides (Double sugars), Polysacchrides (Complex sugars).

Front 5

Name 3 simple sugars

Back 5

Glucose, Galactose, Fructose

Front 6

Three groups of Lipids

Back 6

Neutral fats, Phospholipids, Steroids

Front 7

Lipids

Back 7

Insoluble in water. Soluble in organic liquids such as acetone and ether

Front 8

Saturated

Back 8

Every carbon atom in a chain holds two hydrogens

Front 9

Unsaturated

Back 9

Free space to form bonds on carbon atoms

Front 10

Peptide bond

Back 10

carboxyl group on one amino acid forms a covalent bond between the amino group of another, resulting in the release of a water molecule.

Front 11

The Oparian-Haldane hypothesis

Back 11

Suggested origins of prebiotic synthesis of life on earth based upon basic "building blocks" of compounds found in many living organisms today.

Front 12

Autotrophs

Back 12

Synthesize food from inorganic materials using light or other forms of energy. Ex. Plants

Front 13

Heterotrophs

Back 13

Obtain food directly from their environment. Ex. Cows

Front 14

Cyanobacteria

Back 14

Earliest bacterium like organisms that first appeared on earth about 3 billion years ago.

Front 15

Archaea

Back 15

Kingdom of cyanobactera distinctly different from "true bacteria" (Kingdom Monera) in both ribsomal rna and molecular metabolism.

Front 16

Monera

Back 16

Kingdom of cyanobacteria distinctly different from Archaea in both ribsomal RNA and molecular metabolism.

Front 17

Single celled eukaryotes

Back 17

Arose 1.5 million years ago, according to fossil evidence.
