Diagnosing a Membrane Transport Failure
Captions available
The idea
This capstone diagnoses which membrane transport mechanism has failed in each of three malfunctioning cells, using only the transport concepts this unit's closing block has established.
Where people slip
A cell can transport water, ions, and solutes normally while still failing at endocytosis, since bulk transport depends on a distinct membrane-folding mechanism that ordinary diffusion and carrier proteins do not use.
