Ch 3. PT 1

Question 1

Macromolecules

Answer 1

large molecules composed of thousands of covalently connected atoms. Molecular structure and function are inseparable

Question 2

Polymer

Answer 2

A long molecule consisting of many similar building blocks

Question 3

Monomers

Answer 3

1 polymer. Small building block molecules

Question 4

All living things are made up of the four classes of large biological molecules

Answer 4

1. Carbohydrates
2. Lipids.
3. Proteins
   4 Nucleic acids

Question 5

Three of four classes of life’s organic molecules are polymers:

Answer 5

1. Carbohydrates
2. Proteins
3. Nucleic Acids

Question 6

Dehydration reaction

Answer 6

Occurs when tow monomers bond together through the loss of a water molecule

Question 7

Hydrolysis

Answer 7

When polymers are disassembled to monomers. This reaction is the reverse of the dehydration reaction

Question 8

Dehydration reaction. synthesizing a polymer

Answer 8

Removes a water molecule forming a new bond

Question 9

Hydrolysis: breaking down a polymer

Answer 9

Hydrolysis adds a water molecule, breaking a bond.

Question 10

Carbohydrates

Answer 10

Include sugars and the polymers of sugars

Question 11

Simplest carbohydrates

Answer 11

Monosaccharides which are single sugars

Question 12

Carbohydrate macromolecules

Answer 12

polysaccharides, polymers composed of many sugar building blocks.

Question 13

Monosaccharides

Answer 13

have molecular formulas that are usually multiples of CH2O (carbohydrate)

Question 14

The most common monosaccharide

Answer 14

Glucose (C6H12O6)

Question 15

How are monosaccharides classified?

Answer 15

1. The location of the carbonyl group (as aldose or ketose)

2. The number of carbons in the carbon skeleton
