Questions With Correct Answers
Noradrenallines affect on pacemaker cells - CORRECT ANSWER✔✔-G Protein--
| | | | | | | |
>INcreased cAMP-->increased flow through funny channel--> HR
| | | | | |
Na+ equilibrium potenial - CORRECT ANSWER✔✔-membrane potential that is
| | | | | | | | |
required to stop a net flow of ions across the membrane
| | | | | | | | | |
Threshold potentail - CORRECT ANSWER✔✔-membrane potential that leads to
| | | | | | | | |
the opneing of a channel
| | | |
Action potential - CORRECT ANSWER✔✔-membrane potential change that does
| | | | | | | | |
not diminsh with distance and time when propagated
| | | | | | |
Axon Hillock - CORRECT ANSWER✔✔-location of voltage gated sodim channels on
| | | | | | | | | |
the cell body
| | |
BMR - CORRECT ANSWER✔✔-least energy need ed to maintain.
| | | | | | | |
-aerobic scope=10x BMR (max MR)
| | | |
Saper Paper - CORRECT ANSWER✔✔-mice make UCP's in hypothalamus by
| | | | | | | | | |
attaching hte coding region of an uncoupler gene to regulatory region of an
| | | | | | | | | | | | |
orexion gene |
, -UCP mouse>body weight than WT, lower body temp, same food intake/activity,
| | | | | | | | | | |
greater life span | |
Kleibers Law - CORRECT ANSWER✔✔-BMR=mass^2/3 but originally tried to prove
| | | | | | | | |
it was mass^3/4 but was wrong
| | | | | |
Goose Paper Purpse - CORRECT ANSWER✔✔-The blood of the bar headed goose
| | | | | | | | | | | |
would have an increased temp dependence of O2
| | | | | | |
Bohr Effectt - CORRECT ANSWER✔✔-pH decreases and the partial pressure of
| | | | | | | | | | |
CO2 increases, resulting in lower affinity of Hb for O2
| | | | | | | | |
-results in a shift to the right of coorperative kinetics curve Hb binding of O2
| | | | | | | | | | | | | |
Goose Paper(Temp affect on Hb affinity for O2) - CORRECT ANSWER✔✔-Lung
| | | | | | | | | | |
Temp decreases, O2 affinity increases
| | | |
muscle temp incrases, O2 affinity decreases
| | | | |
Graded Potential - CORRECT ANSWER✔✔-membrane potential change that
| | | | | | | |
diminishes with distance and time when propogated
| | | | | |
Funny channel - CORRECT ANSWER✔✔--voltage gated cation channels that
| | | | | | | | |
remain open when membrane potential is below threshold potential
| | | | | | | |
-generate pacemaker potential that brings membrane potential from resting to
| | | | | | | | | |
threshold
