Chapter 1

Question 1

Ionic bonds

Answer 1

Bond forms when electrons are transferred from one atom to another

Question 2

Covalent Bonds

Answer 2

Bond forms when electrons are shared

Question 3

Nonpolar colavent bonds

Answer 3

Bond formed when electrons are shared equally. Diatomic molecules (O2, H2)

Question 4

Polar covalent bonds

Answer 4

bond formed when electrons are not shared equally. H20.

Question 5

heat capacity

Answer 5

the degree to which subject changes temperature with response to addition/loss of heat

Question 6

Cohesion

Answer 6

attraction of like substances

Question 7

Adhesion

Answer 7

attraction of unlike substances. think velcro

Question 8

Polymer

Answer 8

a polymer consist of repeated monomers

Question 9

glycosidic linkage

Answer 9

links monosacharrides to make a disaccharide. Water molecule is lost during the formation of this bond

Question 10

Monosaccharide

Answer 10

simple unit of sugars

Question 11

polysaccharide

Answer 11

repeating monosacharide units.

examples- starch, glycogen, celluclose, chitin

Question 12

lipids

Answer 12

triglycerides, phospholipid, steriods

Question 13

triglycerids

Answer 13

think fats. Made up of 3 fatty acids + glycerol

Question 14

Phospholipid

Answer 14

2 fatty acids + glycerol + phosphate

Question 15

steriods

Answer 15

4 Carbon ring.

Ex. cholesterol, hormones (estrogen+ testosterone)

Question 16

Protein

Answer 16

made up of amino acids. linked by peptide bonds

Question 17

primary structure

Answer 17

order of amino acids linked by peptide bonds

Question 18

secondary structure

Answer 18

3D shape. formed by hydrogen bonding between amino and carboxyl groups.

Produces alpha helix and beta sheets

Question 19

tertiary structure

Answer 19

3D shape. Dominate structure of the proteins. Includes hydrogen bonding, ionic bonding, hydrophobic effect, and disulfide bonds

Question 20

quartenary structure

Answer 20

protein that has 2 or more separate peptide chains

Question 21

DNA

Answer 21

include deoxyribose, nitrogen base, and phosphate group

Question 22

4 nitrogen bases for DNA

Answer 22

Adenine
Thymine
Cytosine
Guanine

Question 23

cofactors

Answer 23

non protein that assist enzumes

Question 24

cooperativity

Answer 24

enzyme becomes more receptive to additional substrate molecules after one molecule attaches to the active site.
