Question 1

macromolecules

Answer 1

make up the food tat animals eat, which gets broken down during digestion releasing nutrients or the building blocks for (larger) biological molecules

Question 2

what can you also call a carbohydrate

Answer 2

-polysaccharide
-complex carbohydrate

Question 3

sacch means

Answer 3

sugar

Question 4

poly =

Answer 4

many

Question 5

mono-

Answer 5

one

Question 6

after water where does most of the cells weight come from

Answer 6

biological molecules

Question 7

example of inorganic ions

Answer 7

calcium

Question 8

most marcomolecule weight and diveristy comes from

Answer 8

protein

Question 9

three types of macromolecules are

Answer 9

polymers

Question 10

polymer subunits are

Answer 10

monosaccharide
-amino acid
-nucleotide
-peptide

Question 11

macromolecule polymer example

Answer 11

polysaccharide
-protein
-nucleic acid
-polypeptide

Question 12

when are macromolcules broken down

Answer 12

during digestion going through hydrolysis rxns

Question 13

hydrolysis reactions

Answer 13

water breakage. It adds a water molecule breaking a bond between 2 monomer units

Question 14

what catalyzes hydrolysis reactants

Answer 14

enzymes called digestive enzymes or hydrolytic enzymes

Question 15

in dehydration reaction, it goes from _____->______ when water is extracted

Answer 15

monomer to polymer

Question 16

in hydrolysis reaction it goes from ______->______ (water is added)

Answer 16

polymer to monomer

Question 17

what type of bond is being broken during hydrolysis

Answer 17

covalent bond (very strong) holds monomers together

Question 18

chemical nutrients cycle or flow through environment

Answer 18

cycle

Question 19

what is responsible for absorbing monosaccharides and amino acids and transferring these molecules into the blood stream for cellular distribution

Answer 19

small intestine

Question 20

what do food webs show

Answer 20

nutrient AND energy acquisition

Question 21

is an essential nutrient needed in high quantities for survival

Answer 21

no
-your body does not make it but you acquire it (for humans through eating)

Question 22

can you live without non covalent bonds

Answer 22

no they are very important to living life

Question 23

can covalent bonds be polar

Answer 23

yes

Question 24

as temp rises are covalent or non covalent bonds more likely to break

Answer 24

non covalent

Question 25

list some things about hydrophobic interaction

Answer 25

form non polar covalent bonds like C,H
-stabilized by van der waals forces
-they occur when ions and polar molecules including water interact with another through ionic bonds and hydrogen bonds
