DAT bio-302-345 Flashcards
pheromones
can act as sex attractants, mark territories, & accelerate reproductive maturity in a # of species (ex. formic acid by ants, in feces to mark territories)
a pH gradient is seen in what part of photosynthesis/ glycolysis
ETC
function of MHC
major histocompatibility complex distinguishes self- from non self ; responsible for stimulating rejection against the donated organ
pyrimidines and characteristics
cytosine, uracil, thymine, - contain one ring
purines and characteristics
adenine, guanine - contain two rings
technique used widely to elucidate 3-D structure of a macromolecule; to determine 3º structure
X-ray crystallography
exocytosis
it is in the presynaptic membrane where we see synaptic vesicles discharge their contents
neurotransmitter that plays a role in mood swings
seratonin
what does the blood-brain barrier allow passage?
permeable to CO2, O2, glucose, and general anesthetics
whats produced in a fatigue muslce
lactate
under aerobic conditions, most of the pyruvate is oxidized by??
TCA cycle
voice box
larynx
interferons
group of small proteins made by most body cells following a viral attack ; class of gycoproteins called cytokines
algae
bacteria (protist)
blue-green algae
monera
level of greatest biomass; least biomass
plants; 3º consumers
procedure most useful to study intracellular location of proteins; uses radioactive label on a protein to detect whats happening to molecules in cells!
pulse- chase experiment
ubiquinone
coenzyme Q lipid soluble electron carrier seen in the ETC
amphoteric
act as acid or base
whats special about glycine
is the only optically inactive amino acid since it has no chiral carbons
after ovulation the ovarian follicle creates
corpus luteum
corpus luteum
will produce progesterone and estrogen that will help blood vessel growth
whats derived from cholesterol
steroid hormones: estrogen, progesterone, cortisone, cortisol
where are epinephrine a thyroxin derived from
amino acid
true about ferns
vascular plants with large, feathery leaves, large leaves with many veins, fern spores develop on the sporophyte in sporangia; sori, or clusters of sporangia develop on the lower surface of the leaf
reverse transcriptase is found in
Retrovirus
mitosis makes up what % of cell cycle
10%
dioecious species
cannot self-fertilize; spec ices in which each individual is distinctly male or female (mammals and most reptiles)
human population
K-related species; low reproductive rates, constant in size
bacteria population
R-related species ; fast in growth , numerous offspring, fast maturation
haploid stage of life cycle dominates in
fungi
agonistic behavior can result it
two animals conflict over mate or food
casparian strip
waxy band in plants that aid in water control
main solute transported by the phloem
sucrose
nucleic acid backbone consist of
sugar and phosphate units
myoglobin structure
single chain, no quaternary structure
in glomerular filtrate, whats completely reabsorbed
K+
