Endocytosis and exocytosis are the bulk transport mechanisms used in eukaryotes. As these transport processes require energy, they are known as active transport processes. Vesicle function in ...

In all eukaryotic cells, the constitutive processes of exocytosis and endocytosis maintain the flow of material to and from the cell surface. In secretory active cells, these processes have to be ...

Vesicles were captured at small, discrete active zones near the terminal surface. An electric stimulus caused them to undergo rapid exocytosis, seen as the release of a fluorescent lipid from the ...

The alternative to active transport is passive transport ... are moved across cell membranes through the processes of endocytosis or exocytosis. In endocytosis, the cellular membrane folds ...

In clathrin-mediated endocytosis, the cell membrane invaginates ... In Drosophila, DAP160 surrounds the active zone and contains AP-2. In cases where DAP160 function is abrogated, the synaptic ...
