Functions
Of Enzymes
BACK SIDE:





Enzymes are proteins
Fit with substrate like a “Lock and Key” –
if enzymes “denatures” it won’t fit!
Act as a “catalyst” (speed up reactions)
Lower activation energy
Work best at “Optimum” conditions!
(this is different for each enzyme)

membrane bound
organelles and a nucleus)

saltier than usual
environments
because of osmosis!!

Photosynthesis
And
Cellular Respiration
*Opposites of each other*
Photosynthesis
 Converts sunlight into chemical energy

to the ribosome, anticodon
pairs with mRNA codon

Genotypes
EOC Flashcard 20
Paths of Inheritance
(be able to do punnett
squares)





Dominant = one allele
dominant
Recessive = allele “hidden” by
dominant
Codominance= both alleles
equal, both show up! (AB)
Incomplete Dominance =
Neither allele dominant,
blending together (AA’)
Sex-linked = on X
chromosome, no male carriers
(XA Xa)
EOC Flashcard 21
Karyotype



Picture of
chromosomes (should
have a total of 46 (23
pairs)
Shows chromosomal
abnormalities (Ex.
Down’s Syndrome =
Trisomy 21)
Usually follows an
amniocentesis
EOC Flashcard 22
Pedigrees
Parents are
carriers!
Rules to Remember:
1. Filled in shapes have the trait
2. Trait may be dominant or recessive!
3. If trait skips a generation, it’s probably recessive
4. Sex-linked traits are passed from mother to son
EOC Flashcard 23
Viruses


Not living because they
cannot reproduce outside
a living organism (not
made of cells)
Two reproductive cycles


Lytic – fast, destroys cell

genetic material hides in
cell

separated.
Genetic diversity – by
mutation or in gene pool
Natural selection

from ovary of plant.)
EOC Flashcard 33
Behaviors as Adaptations




Instinctive behaviors
improve survival rates.
Protective behaviors
(spray, teeth bared) turn
predators away and
defends resources
Parental behaviors
(advanced in birds and
mammals) increase
survival of young.
Communication and
courtship allow mate
recognition
EOC Flashcard 34

instinct)

EOC Flashcard 37
Carbon Cycle
Carbon Cycle
 - Respiration releases carbon
as CO2 (carbon dioxide)
 Photosynthesis removes
carbon and makes sugar
(C6H12O6)
Human Impact
 Burning Fossil fuels releases
CO2
 Deforestation increases the
amount of CO2 in the
atmosphere
EOC Flashcard 38
Symbiosis
 Mutualism
 Parasitism
 Commensalism
Two species “living
together” permanently



Mutualism (+ +) both
benefit
Parasitism (+ -) One is
harmed
Commensalism (+, 0)
one benefits, the other is
neutral
EOC Flashcard 39
Environmental Problems



Overpopulation – cause
of all environmental
problems
Global warming – too
much CO2 in atmosphere
increases average global
temperature ->flooding,
climate change
Acid Precipitation –
caused when NOx and
Sox react with water
vapor  lower pH of soil
and aquatic ecosystems
EOC Flashcard 40
Biomagnification


Pesticides and
contaminants “move up
the food chain”
Chemical contaminants
are stored
(bioaccumulation) and
magnified in organisms
higher up the food chain
because predators
accumulate pesticides in
the bodies of their prey.
