misc things Flashcards
direction of na+ transport during co transport w/ glucose
out of the cell
golgi apparatus function
process and packages proteins and lipids
golgi vesicles function
directs molecules to the correct destination
ser function
synthesises lipids and phospholipids
rer function
synthesises proteins
why is there blood flow between lamellae
maintains countercurrent
what happens after glycolysis if aerobic respiration is happening
pyruvate enters the mitochondrial matrix via active transport
cholinergic synapse vs nmj differences
synapse is between neurones, nmj is between a synapse and a muscle
synapse can inhibit or excite, nmj is just excitory
artery structure
thick smooth muscle and elastic fibres, narrow lumen
arteriole structure
thin layer and wider lumen
larger diameter axons…
have less resistance facing ion flow so conduct faster
what happens to some of the energy released from photoionisation
conserved in the production of atp and nadph
pcr- stages and temperatures
separation 92c
priming 55c
synthesis 72c
types of stem cell in embryos
totipotent- all, includes placenta/umbilical cord
pluripotent- most
what is transcription inhibited by?
increased methylation
decreased acetylation
