pyrimidine
CT, ONE RING STRUCTURE
purine
AG TWO RING STRUCTURE
cystine
contains a sulfhydryl group
lysosome
when a macrophage ingests material, it becomes trapped in a phagosome, which then fuses with a lysosome to form a phagolysosome. This is where enzymes digest the object.
golgi apparatus
proteins from the ER are either transported, modified, and packed into vesicles for delivery to target destinations
Endoplasmic reticulum
Ca2+ storage, protein synthesis and lipid metabolism
active transport
movement of charged ions against their concentration gradient.
high isoelectric points
indicate a positive charge at physiological pH (basic)
nuclear localization sequence
short stretch of amino acids that mediated the transport of nuclear proteins into the nucleus
GAPDH
catalyzes the reversible conversion of G3P to 1,3Bisphosphoglycerate
Vasopressin
regulates the fusion of aquaporins with the apical membranes of the collecting duct epithelial cells.
microglia
immune cells of the brain.
astrocyte
subtype of glial cell, majority of cells in CNS. Perform metabolic, structural, homeostatic and neuroprotective tasks
schwann cells
myelin forming cells in the PNS
oligodendrocytes
production of myelin in CNS
Blood from the small intestine is transported first to…
the liver in order to have toxins removed.
determine percentage increase
total percentage / initial percentage. The numbers after the decimal will indicate the percent increase
endosomes
involved in the internalization of particles through endocytosis
proteases
digest proteins into smaller fragments
citric acid cycle products
Can I Keep Selling Sex For Money Officer
citrate, isocitrate, a-ketoglutaratem, succinyl co-a, succinate, matale, oxaloate
motor proteins
move along microfilaments through interaction with actin.
tubulin
protein that forms long chains that form microtubules
actin
protein that forms (w myosin) contractile filaments of muscle cells, involved in motion in other types of cells/
centrosomes
area of microtubule origin
