T or F: PO2 levels are strong drivers of respiration.
Choose an answer
1 True 2 False
Don't know?
Terms in this set (60)
Epithelial transport is not Gap junctions 2 multiple choice options
dependent upon:
Which transporter do Na+/K+ ATPase Pump 3 multiple choice options
nearly all other
transporters ultimately
depend upon for the
transport of substances
across epithelia?
, The movement of Transcellular transport
substances through a cell
via active transport
The movement of Paracellular transport
substances through
adjacent epithelial cells
via tight junctions
In a parallel universe, our +30mV 3 multiple choice options
cells are highly
permeable to Na+
(Equilibrium potential of
35+mV) and weakly
permeable to K+
(Equilibrium potential of
-90mV), what would you
estimate for the resting
membrane potential of
these cells?
The equilibrium potential Concentration gradient and charge
is determined by what
two things?
The resting membrane Concentration gradient and permeability
potential is determined
by what two things?
The electrical state of a Resting Membrane Potential
cell at rest
When there is no net Equilibrium Potential
movement of ions
What two channels L-type channels (Ca2+ in), voltage gated K+ channels
directly account for the (K+ out)
plateau phase of the
cardiac contractile cell?
What channel is Voltage gated Na+ channel
responsible for the
depolarization phase of
the contractile cell?
