Once bound to cargo, it enters the cell via COPII-mediated endocytosis

It is shuttled back to the cell surface after it delivers its cargo

It releases its cargo in the low pH environment of the endosome

Its cargo is low density lipoprotein

None of these can be concluded

Cell expends energy to transport this molecule

Cell does not expend energy to transport this molecule

The molecule is found in higher concentration outside the cell

Active transport

Passive diffusion

Cotransport

Facilitated diffusion

Secondary active transport

Sodium-potassium pump because it involves active transport

Sodium-potassium pump because it involves passive transport

Potassium channels because it involves active transport

More than one of these are true

When the cell is in a hypotonic solution

When the cell is in an isotonic solution

When there is more solute outside of the cell compared to inside the cell

When the cell is hypotonic to its surrounding environment
