Biological molecules 1

Question 1

define monomer

Answer 1

small units that make polymers

Question 2

define polymer

Answer 2

made out of monomers

Question 3

define condensation

Answer 3

chemical reaction joining monomers into polymers, elimination of a water molecule

Question 4

define hydroylis

Answer 4

breaking bonds(polymers into monomers) using water molecule

Question 5

Types of monosaccharides and what is is

Answer 5

glucose (alpha and beta), galactose, fructose, a simple sugar

Question 6

types of monomers

Answer 6

monosaccharides, amino acids and nucleotides

Question 7

how to make a disaccharide and give examples

Answer 7

condensation of 2 monosaccharides
glucose and glucose is maltose
glucose and galactode is lactose
glucose and fructose is sucrose

Question 8

draw all 4 monosaccharides

Question 9

draw all 3 disaccharides

Question 10

types of reducing sugars

Answer 10

glucose galactose and fructose(monosaccharides) and maltose and lactose

Question 11

types of non reducing sugars

Answer 11

some disaccharides and all polysaccharides

Question 12

what 2 polysaccharides are starch made out of?

Answer 12

amylose and amylopectin

Question 13

what glucose molecules is starch

Answer 13

alpha glucose

Question 14

why is starch a good storage molecule: amylose

Answer 14

long, unbranched,coiled =making it compacted

Question 15

why is starch a good storage molecule: amylopectin

Answer 15

long, branched
sidebranches =enzymes break glycocidic bonds= quick release of glucose

Question 16

why else is starch good? hint water

Answer 16

insoluble, uneffect water potential meaning it doesnt swell up

Question 17

what organism stores glucose as starch

Answer 17

plants

Question 18

what is the storgage for animals

Answer 18

glycogen

Question 19

why is glycogen good for storage?

Answer 19

like amylopectin, has more side branches= quicker release,
very compacted

Question 20

what are cell walls made of?

Answer 20

cellulose

Question 21

structure and facts about cellulose

Answer 21

beta glucose joined with glycosidic
hydrogen bondhydrogen bonds verticle/ adjectent(strong)=microfibers
structural support
