Macromolecule
carbohydrates
Building Block
monosaccharides
a.k.a. simple sugars
lipids
fatty acids & glycerol
proteins
amino acids
nucleic acids
nucleotides
Mitosis
Purpose:
GROWTH &
REPAIR,
ASEXUAL
reproduction for
unicellular
organisms
Results: two
identical cells
that are identical
to the parent cell
Examples
starch,
glycogen,
glucose,
sucrose, end in
“-OSE”
fats, oils,
waxes, steroids
insulin, keratin,
actin, myosin,
enzymes (end
in “-ASE”
DNA & RNA
only
Meiosis
Purpose: MAKE
SPERM & EGG
(gametes) for
SEXUAL
REPRODUCTION
Results: four
genetically unique
cells with half the
number of
chromosomes as the
parent
Function
ENERGY
How to remember?
“kids on pixie sticks,”
saccharine means “sweet”
water repellant, store
energy
cell/body structures,
speed up reactions
salad dressing, ski wax,
fatty acids=fats
eat chicken and meat to
build muscle
transmit genetic info
(DNA)
protein synthesis (RNA)
nucleotide=nucleic acid
Active transport
moves molecules from
low to high
concentration through
protein channels,
requires energy (that’s
why it’s “active”)
Passive Transport
moves molecules from
high to low
concentration, no
energy needed –
diffusion, osmosis,
facilitated diffusion (FD
uses protein channels)
