What else can I help you with?
Within the axonal endings are many small vesicles containing a neurotransmitter substance called?
Acetylcholine
Which process describes the ATP requiring movement of extremely large sub substances out of a cell in pockets called vesicles?
The process that describes the ATP-requiring movement of extremely large substances out of a cell in pockets called vesicles is known as exocytosis. During exocytosis, vesicles containing the substances fuse with the cell membrane, releasing their contents into the extracellular space. This mechanism is crucial for processes such as neurotransmitter release and the secretion of hormones.
A chemical found in the synaptic vesicles that when released has an effect on the next cell is called a?
neurotransmitters
What are specialized vesicles containing enzymes?
The special vesicles containing enzymes are called Lysosomes.
Which transport process does the cell use to direct the contents of vecicles out of the cell membrane?
The transport process used by the cell to direct the contents of vesicles out of the cell membrane is called exocytosis. In this process, vesicles containing substances fuse with the cell membrane, allowing their contents to be released into the extracellular space. Exocytosis is crucial for various functions, including hormone secretion and neurotransmitter release.
What are the small sacs within the axon terminal called?
They are called as vesicles. They are constantly created. They contents the neurotransmitter. Neurotransmitter is required for transmission of the nerve impulse.
What are the vesicles containing enzymes that neutralize toxins such as alcohol?
The vesicles containing enzymes that neutralize toxins such as alcohol are called peroxisomes. These organelles contain enzymes like catalase that break down toxic molecules like hydrogen peroxide into non-toxic substances, aiding in detoxification processes in the cell.
What is the process of a neurotransmitter being absorbed into the axon terminal?
When an action potential reaches the axon terminal, it triggers the opening of voltage-gated calcium channels. Calcium ions enter the axon terminal, leading to the fusion of neurotransmitter-containing vesicles with the synaptic membrane. The neurotransmitter is then released into the synaptic cleft where it can bind to receptors on the postsynaptic neuron.
What ion enters the axon nerve terminal to cause exocytosis of the neurotransmitter is called?
The ion that enters the axon nerve terminal to trigger neurotransmitter release is calcium (Ca2+). When an action potential reaches the nerve terminal, voltage-gated calcium channels open, allowing calcium ions to flow into the cell and initiate the process of exocytosis of neurotransmitter-containing vesicles.
What is it called when vesicles are used to moved substances out of cells?
Endocytosis
What is called when vesicles are used to move substances out the cell?
Exocytosis
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.
