Flashcards in Lecture 3 Deck (28):
1

large biologically relevant molecules

macromolecule

2

what are the 4 macromolecules?

Proteins, Nucleic Acids,
Carbohydrates, Lipids

3

Made of C, H, O in a 1:2:1 ratio
Are used as energy source or as structural
components or cells and organisms

carbohydrates

4

A monomer of a polysaccharide

monosaccharide, or simple sugar.

5

6-Carbon sugars

hexose

6

5-Carbon sugars

pentose

7

3-Carbon sugar

triose

8

carbs biochemistry p 6

yes

9

Most important carbohydrate in terms of energy
consumption and storage

glucose

10

which glucose you can eat?

alpha

11

Monosaccharides joined by

glycosidic bonds

12

polymers made of 2 simple sugars

disccharides

13

long chains of α-glucose. Used as energy
storage. These can be hundreds of glucose
molecules long. Found in plants.

starch

14

Contain the information necessary for the
successful functioning of the cell and heredity

nucleic acid

15

monomers of nucleic acid

nucleotides

16

structure of nucleotide

comprised of a phosphate group,
a pentose (5-Carbon) sugar (varies with the
nucleic acid), and a nitrogenous base

17

5 different nitrogenous base

purines: adenine and guanine
pyrimidines: cytosine, thymine(DNA) and Uracil (RNA)

18

Nucleotides are joined by _________________
between sugars and phosphate groups

phosphodiester bonds

19

dna sugar

Sugar present is deoxyribose

20

rna sugar

Made of ribose sugar

21

It is used as the energy currency of the cell

ATP

22

name the 8 functions of proteins

Hormonal protein
Receptor protein
Contractile and motor protein
Structural protein
enzymatic protein
defensive protein
storage protein
transport protein

23

all are water insoluble and hydrophobic

lipids

24

Fat molecules are commonly called

triglycerides

25

Fatty acids can be...

saturated, monounsaturated
or polyunsaturated

26

important in cell growth and
cell structure

steroid

27

important in the structure of the
cell membrane

cholesterol

28

control cell growth

testosterone
