\.Imagine an exercising muscle cell that requires a constant supply of oxygen to
avoid fatigue. At which of the following distances from a capillary would you
predict these muscle cells to have sufficient oxygen delivery?
0.5 m
2 nm
2 mm
20 nm - ANSWERS✔-We know from the lecture material that a diffusion can
transport in 1 ms over a distance of 20 nm, so it should be even faster at shorter
distances.
\.Which of the following factors increase the rate of diffusion across a membrane?
Increasing membrane permeability
Increasing the solute concentration difference across the membrane
Increasing membrane thickness
Increasing the membrane area - ANSWERS✔-Increasing membrane permeability
