AAMC FL2 Bio/Biochem Missed Concepts Flashcards
biology
pyrimidines
cytosine
uracil
thymine
Biology
Purine
adenine
guanine
Biology
Active Transport
Moving ions into the cell against their concentration gradient, requiring energy
Biochemistry
pI (isoelectric point)
the pH at which the net charge of a protein molecule is zero
Biochemistry
When pI < pH the protein is
negatively charged
Ex) pI = 5 < pH = 7.2
Biochemistry
When pI > pH the protein is
positively charged
Ex) pI = 9 > pH = 7.2
Biology
Ubiquitination
targets a protein for degradation by a proteasome
Biochemistry
glycolysis occurs where?
cytoplasm
Biochemistry
CAC occurs where
mitrochondrial matrix
Biochemistry
oxidative metabolism occurs where?
internal folded mitochondrial membranes (cristae)
Biochemistry
ETC occurs where?
inner mitochondrial membrane
Biology
Southern Blot
DNA
Biology
Northern Blot
RNA
Biology
Western Blot
Proteins
Biology
Epithelial Cells
- cover outer surface of internal organs and the body
- secretory, transporting, regulatory functions
Biology
Endothelial Cells
- line the cavities of the circulatory system
- provide slippery, non-sticky surfaces for the flow of fluids
Biology
Astrocytes
- CNS
- maintain blood brain barrier
- regulation and perfom metabolite support
Biology
Ependymal Cells
- CNS
- line spinal cord & ventricles of the brain
- produces cerebrospinal fluid
Biology
Oligodendrocytes
- CNS
- myelinate CNS axons
- provide structural framework
Biology
Microglia
- CNS
- Brain’s immune cells
- remove dead cells and pathogens by phagocytosis
Biology
Schwann Cells
- PNS
- Myelinate neurons in PNS
- maintenance and regeneration of neurons after injury
Biology
Prion
abnormaly folded protein that induces a normally folded version of the protein to also adopt the abnormal structure, which is also deleterious
Biology
Proteases
digest proteins into smaller fragments
Biochemistry
How many moles of ATP are produced in anerobic conditions?
2 moles
Biochemistry
how many moles of ATP are produced in aerobic conditions?
38 moles
36 from CAC + ETC and 2 from glycolysis
Biology
What organs arise from the ectoderm
brain/nervous system
Biology
What organs are derived from the mesoderm
kidney
heart
skeletal muscle
Biology
Microtubules originate from?
centrosomes
