Transport vesicles can move molecules between locations inside the cell, e.g., proteins from the rough endoplasmic reticulum to the Golgi apparatus.
Synaptic vesicles are located at presynaptic terminals in neurons and store neurotransmitters.
Portions of the ER are pinched off, forming transport vesicles. These carry their load of proteins to the Golgi apparatus. The membrane of the transport vesicle fuses with the membrane of the Golgi apparatus, merging their contents.
Lysosomal hydrolytic enzymes are manufactured in the rough endoplasmic reticulum (Rough ER), from whence they are transferred in a transport vesicle to the cis face of the Golgi apparatus or complex (see Figure 1).

Cytoskeleton Internal scaffolding of cells, made up of microfilaments, intermediate filaments, and microtubules, which enables cells to transport vesicles, change shape, and migrate.
