BIG IDEA I: BIOSPHERE

Ecosystem- such as the tundra

Communities- all biotic components in an area

Population- made up of plants, animals, and microorganisms

Organisms- such as polar bears in the tundra

Organ systems: such as the repitory system in the polar bear

organs- heart

tissue

cells- heart cell

organelles- lysosomes

molecules

BIG IDEA II: Chloroplasts

Calvin Cycle (no light)

CO2 fixed into G3P---> to carbohydrate

light reactions (uses light)

light strikes pigment molecule in PSII ; excites e- till it reaches the primary electron acceptor; makes NADPH & ATP

BIG IDEA III: Meiosis

Recessive

compared to dominant traits- do not have as much of an impact on expressed genes

Genotype

an organisms full hereditary information rvrn though not expressed always

Dominant

have a large impact on expressed gene

Phenotyes

organisms actual observed properties

BIG IDEA II: CELLULAR RESPIRATION

Oxidative Phosphorylation

ETC and cheiosmosis (inner mitochondrial membrane)

26 or 28 ATP

Subtrate Level Phosphorylation

Kreb's Cycle (2 cycle) matrix

1 FADH2

1 ATP

2 NADH+

3 NADH+

2 CO2

Glycolysis

Payoff

2 Pyruvate

4 ATP formed

Investment

2 ATP used

BIG IDEA I: Hydrogen Bonding

Expansion with freezing:

H bonds hard to break in crystal lattice formed by ice

Water is a very influential and versatile substance necessary to the life on earth. Therefore, it would have been placed at the top of the concept map since it relates to all the big ides in some form or fashion

Ability to Moderate Temperate

-

heat of vaporization

specific heat: amount of heat needed to raise one gram of a substance by 1 degree C

Cohesive Behavior

surface tension- responsible for dome shape

adhesive vs. cohesive

BIG IDEA III: Replication

Eukaryotes

replication occurs in the nucleus

Enzyme

DNA ligase

DNA Poly I & II

primase- synthesizes an RNA primer a 5' of leading strand and of each Okazaki fragment of lagging strand

topioisomerase- relieves the unwinding of the double helix

SSB- keeps this unwound

helicase- unwinds double helix at replication forks

Antiparallel

complementary base pairing

Prokaryotes

occurs in tht cytoplasm

Floating topic

BIG IDEA I: SRP

Polypetide not fully formed; attached to ribosome

SRP attaches to the signal petide chain

SRP leads the not fully formed peptide to the attached ribosome on the ER

Once there, the peptide chain continues to synthesize into the ER lumen; peptidase cuts off the synthsized chain

After being modified in the ER, vessicles travel on microtubules bringing the polypeptide chain to the Golgi for further modification

Once in the Golgi the protein can go four places

lysosomes

plasma membrane for secretion

back to the ER
