Chapter 2 PPT Flashcards
when energy is actually doing work
kinetic
results from the movement of charged particles - ions
electrical energy
building blocks of elements
atoms
have the same number of protons and electrons so same atomic number
isotopes
vary in number of neutrons so different atomic masses
isotopes
process of spontaneous atomic decay
radioactivity
what are the particles release by radioactivity
alpha, beta and gamma rays
two or more atoms combined chemically
molecule
two or more DIFFERENT atoms combined chemically
compound
negatively charged ions
anions
positively charged ions
cations
form when electrons are completely transferred from one atom to another
ionic bonds
can either donate or accept electrons
ions
atoms become stable through shared electrons
covalent bonds
share one electron pair
single covalent bonds
share two electron pairs
double covalent bonds
can be found outside?
valent
hydrogen is attracted to negative portion of polar molecule
hydrogen bonds
provide attraction between molecules
hydrogen molecule
carries a positive and negative region
polar
synthesis reaction
A+B —-> AB
atoms or molecules are combined
synthesis reaction
anabolic reaction
synthesis reaction
reaction that absorbs or consume energy
anabolic
building blocks of protein
amino acids
proteins participate in?
muscular hyperthrophy or paglaki ng muscles
AB—> A+B
decomposition reaction
catabolic
decomposition
process that produces energy
catabolic
involves both synthesis and decomposition reactions
exchange reaction
have carbon
organic compounds
do not have / lack carbon
inorganic compounds
absorbs pressure to lessen the damage
cerebro spinal fluid
able to dissolve many substances if they are polar
good solvent
water molecules adhere to one another across surface
surface tension
water will rise up in a tube due to cohesion and adhesion
capillarity
include electrolytes which conduct electrical currents
salt
important inorganic compounds
water, salt, acid, baes and pH
easily dissociate into ions in the presence of water
salt
the more hydrogen ions it contains
the more acidic the substance
taste sour
acids
below 7
acid
MARAMING HYDROXIDE IONS
BASES
neutralized the acid in vaginal canal to make the sperm cell survive
semen being a base
Power of Hydrogen
pH
measures relative concentration of hydrogen ions
pH
most are covalently bonded
organic compound
C6H1206
GLUCOSE
1:2:1 ratio
carbohydrates
include sugars and starches also classified according to size
carbohydrates
simple sugars and in linear or ring forms
monosaccharides
examples of monosaccharides
glucose, fructose, ribose, galactose and deoxyribose
highly toxic and cancerous form of artificial sugar found in coffees
saccharin
monosodium glutamate (bechin)
cause malignansy nakikita sa mga titsarya
disaccharide
two simple sugars joined by dehydration synthesis
decomposed by hydrolysis
breaking of bonds by adding water back in
glucose + fructose
sucrose
glucose +glucose
maltose
glucose + galactose
lactose
dehydration synthesis
removal of water to form bond
long branching chains of linked sugars
polysaccharide
plant polysaccharides (cellulose is indigestible)
starch and cellulose
animal polysaccharide
glycogen
what kind of sugar does the brain only use
glucose
lipids
fats
insoluble in water, non-polar, but some have polar heads
lipids
healthy fats
poly unsaturated fatty acids
animal fats
saturated fatty acids
healthy or plant fats
poly unsaturated fatty acids
all single bonds, solids at room temperature, animal fats, pile-up on sides of vesseld
saturated
some are double bonds, liquids at room temperature and plant fats
unsaturated
all single bonds, solids at room temperature, animal fats, pile-up on sides of vessels
saturated
neutral fats
triglycerides
composed of three fatty acids
triglycerides
phospholipids are composed of 2 fatty acids
glycerol and phosphate head
form cell membranes
phospholipid
steroids
cholesterol, bile salts, vitamin D and some hormones
bile salts
metabolic products on the composition ng lipids inside an animal being
3 interlocking 6-c rings, a 5-ring and a fatty acid chain
steroids
cholesterol esther
steroids
form peptide bonds through dehydration synthesis
proteins
CHO lagyan ng nitrogen minsan sulfure
protein
made up of amino acids
protein
