What is the process of vesicles releasing their contents outside the cell?
Exocytosis
What is a process by which vesicles release their contents outside the cell?
The process by which vesicles release their contents outside the cell is called exocytosis. During exocytosis, vesicles containing substances, such as hormones or neurotransmitters, fuse with the cell membrane. This fusion allows the contents of the vesicle to be expelled into the extracellular space. Exocytosis is essential for various cellular functions, including communication and secretion.
How do the vesicles know when to move to the membrane and dump their contents into the synaptic cleft?
Vesicles know when to move to the membrane and release their contents into the synaptic cleft primarily through the influx of calcium ions (Ca²⁺) triggered by an action potential. When the action potential reaches the axon terminal, voltage-gated calcium channels open, allowing Ca²⁺ to flow into the neuron. This increase in intracellular calcium levels signals the vesicles to undergo a process called exocytosis, where they fuse with the presynaptic membrane and release neurotransmitters into the synaptic cleft. Additionally, molecular machinery, such as SNARE proteins, facilitates the docking and fusion of the vesicles with the membrane.
The transport mechanism for a neurotransmitter across the synaptic cleft is called?
The transport mechanism for a neurotransmitter across the synaptic cleft is called exocytosis. During exocytosis, neurotransmitter-filled vesicles fuse with the presynaptic membrane, releasing the neurotransmitter into the synaptic cleft where it can then bind to receptors on the postsynaptic membrane.
What means of membrane transport is used to release the neurotransmitter into the synaptic cleft?
Neurotransmitters are released from the nerve terminals by a specialized exocytosis process, synaptic vesicles. These are small nearly uniform capsules that join with the cell membrane to expel their contents. Release is both quantal (set amount) and mediated by calcium.

Which transport process does the cell use to direct the contents of vesicles out of the cell membrane?
Exocytosis
What is the reverse process of endocytosis called?
Nnice attemptu, but the correct answer is exocytosis. The prefix should have been an indicator. Pinocytosis: A process of taking in fluidtogether with its contents into the cell by forming narrow channels through its membrane that pinch off into vesicles, and fuse with lysosomes that hydrolyze or break down contents. Exocytosis is when materials leave the cell by the membrane "spitting it out". Endocytosis is the transport of larger matters into or out of the cell.
