Neurotransmitters are ________. A. chemicals that cross the synaptic gap and bind to receptors on another neuron B. excitatory c
hemicals that make it more likely that a neuron will fire C. inhibitory chemicals that make it less likely that a neuron will fire D. all of these options
A. chemicals that cross the synaptic gap and bind to receptors on another neuron
Explanation:
neurotransmitter are messenger that carries signals between neurons and other body cell. They operate through neurotransmission
This is done by transmission of signals between neurons. Neurons are not linked together and for signals to be transmitted it have to cross over though a space called synapse between this neuron to another neuron.
Neurotransmitter control brain activity and some other body activity such as heart rate,food appetite,fear,fright.
Yes! Neurotransmitters are chemical compounds that are produced from the terminal of a neuron and bound by specific protein in the adjacent neuron where it helps to transmits a nerve impulse.
Neurotransmitters can be:
- Excitatory such as acetylcholine that cause muscle to contract and gland cells to produce secretions (i.e neuron will fire)
- Or inhibitory such as glycine which inhibits the contractions of muscles (i.e neuron did not fire)
Thus, neurotransmitters do all of the functions provided
A scientific law predicts the results of certain initial conditions. It might predict your unborn child’s possible hair colors, or how far a baseball travels when launched at a certain angle. In contrast, a theory tries to provide the most logical explanation about why things happen as they do.
Organic molecules mainly have covalent bonds whereas, in inorganic molecules, there are covalent and ionic bonds. • Inorganic molecules cannot form long chained polymers as organic molecules do.
