How Cells Move Materials In and Out
Description
Cells move materials in and out of the cell by endocytosis and exocytosis. Endocytosis brings substances in from the extracellular environment, while exocytosis releases molecules to the outside. Both processes use vesicles, which are lipid membrane-bound sacs.
These membrane transport steps are ...

Transcript
Endocytic and exocytic pathways are critical for cellular homeostasis, tissue function, and overall cell survival. Simply put, endocytosis is the process that a cell uses to take in molecules from the extracellular space by folding its membrane around it and forming a vesicle. Exocytosis is the reverse process, which uses vesi...
