Front 1

How to find mass of one mole from formula

Back 1

mass= moles X molar mass

Front 2

pervernt equation

Back 2

P= kPA
V= L
N= moles
R= 8.314 kPA
t= k

Front 3

Solute vs Solvent

Back 3

Solute= small
Solvent= big

Front 4

Mass number vs Atomic Number

Back 4

Mass= bigger one "protons plus neutrons"
Atomic= protons/electrons

Front 5

Steps of mass spec and goal of mass spec

Back 5

VIADefDet
measure mass of atom in carbon

Front 6

Where are groups and periods

Back 6

groups- vertical
periods- horiz.

Front 7

First ionization energy

Back 7

minimum value needed to remove electron from a gaseous atom leaving a gaseous ion

Front 8

Glucose has this on the end of its straight chain
Fructose has this

Back 8

Glucose: c=o-h
Fructose: c=o

Front 9

Functions of carbs

Back 9

1. Energy storage
2. Energy source
3. Precursor for molecules like DNA

Front 10

condensation of monosacharrides produces... then...

Back 10

produces water then the Oxygen left over forms a glycosidic linkage

Front 11

dietary fibre

Back 11

helps ya poop

Front 12

3 lipids in human body

Back 12

1. phospholipids (contains a phosphate group)
2. tryclycerides (contains a glyceral)
3. cholesterol

Front 13

HDL vs LDL

Back 13

HDL: Good cholesterol- takes out of arteries and moves to liver
LDL: Bad cholesterol- moves it to arteries

Front 14

saturated vs unsaturated (what looks diff)

Back 14

unsaturated is bent with a c=c bond

Front 15

imp. roles of lipids and neg effects

Back 15

imp roles:
1. insulation and protection
2. energy source
3. structural comp. of cells

neg.
1. increased risk of heart attack
2. obesity

Front 16

hormones: production & function

Back 16

secreted in brain and transferred to various areas of body sending chemical messages

Types: adrenaline, thyroxine, insulin

Front 17

cholesterol and sex hormones both have... but differ in...

Back 17

steroid backbone... where they are located

cholesterol composition is more complicated

Front 18

increased substrate concentration will lead to..

Back 18

increased prob of enzyme colliding with substrate= increased rate of reaction

Front 19

competitive vs noncompetitive

Back 19

competitive= inhibitor will stick itself @ active site. increased substrate will help.

non= inhibitor will put itself @ bottom which will change shape. increased sub. will not help

Front 20

bad stuff for enzymes: heavy metal ions, PH, temp (why)

Back 20

heavy metal ions= poison
PH/temp: desires specific

Front 21

nucleotides consist of...

Back 21

phosphate group, sugar, base

Front 22

RNA contains/DNA containst

Back 22

RNA- ribose, uracil, single stranded
DNA- deoxyribose, thyamine, double helix held by H bonds

Front 23

DNA profiling helps to...

Back 23

find similiarites and differences when comparing DNA

Front 24

Aerobic vs anaerobic respiration of glucose

Back 24

aerobic= uses O2/oxidation of food/makes energy
anaerobic= no O2, oxidation of NADH to NAD/wastes energy

Front 25

INTERmolecular forces

Back 25

1. hydrogen bonding (w/ h's)
2. dipole dipole
3. van der walls (electrons happen to be on one side ya)

Front 26

Bronstead lowry bases and acids

Back 26

acids- donate proton
basis- recieve proton

Front 27

Lewis theory bases and acids

Back 27

acids- recieve electron pair
bases- donate electron pair

Front 28

strong acids

Back 28

dissociate completely in water, higher conductivity, faster reaction, less safe

weak-opposite
