Chaper 2 Test 1

Question 1

Carbohydrates

Answer 1

Are organic molecules composed primarily of carbon hydrogen and oxygen atoms and range in sizes small very large

Question 2

Monosaccharides

Answer 2

Large carbohydrates are composed of numerous relatively simple building blocks simple sugars
Examples
Ribose, deoxyribose, glucose

Question 3

Isomers

Answer 3

Common 6 carbon sugars such as a glucose fructose and galactose
Which are molecules that have the same number and types of atoms but differ in their 3 dimensional arrangement

Question 4

Disaccharides

Answer 4

Are composed of two monosaccharides bound together through a dehydration reaction
Example
Sucrose lactose maltose

Question 5

Sucrose

Answer 5

Glue close and fructose combine to form a disscharide

Question 6

Polysaccharide

Answer 6

Our long chains of monosaccharides
Examples
Cellulose starch and glycogen

Question 7

Glycogen

Answer 7

Or animal starch is a multi branched polysaccharide composed of many glucose molecules

Is the main storage form of glucose in humans

Question 8

Starch and cellulose

Answer 8

• To polysaccharides found in plants
• Both are composed of long chains of glucose
• Plants use starch as an energy storage molecule

Question 9

Lipids

Answer 9

A major group of organic modules are relatively insoluble in water

Question 10

Fats

Answer 10

Major type of lipid

The fats humans and just are broken down by hydrolysis reactions and Celso release energy for use by those cells

Question 11

Triglycerides

Answer 11

Constitute 95% of the fats in the human body

-two different types of building blocks one glycerol and three fatty acids

Question 12

Glycerol

Answer 12

Is a three carbon molecule with a hydroxyl group attached to each carbon Atom

Question 13

Fatty acid

Answer 13

Is a straight chain of carbon atom with a carboxyl group attached at one end

Question 14

Carboxyl

Answer 14

Consist of both oxygen atom and a hydroxyl group attached to a carbon atom

Question 15

Saturated

Answer 15

It contains only single covalent bonds between carbon Atoms

example beef pork for milk

Question 16

Unsaturated

Answer 16

If he has one or more double covalent bonds between carbon Atoms

Question 17

Monounsaturated fats

Answer 17

Have one double covalent bond between carbon Atoms

Olive and peanut oils

Question 18

Polyunsaturated fats

Answer 18

Two or more double covalent bonds between carbon Atoms

Fish oils
Corn
