Neurotransmitters are . A. chemicals that cross the synaptic gap and bind to receptors on another neuron B. excitatory chemicals 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

Option D) all of these options

Explanation:

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. 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.

im gonna compare the cells to jobs in factory. give brainliest

job in the factory //       cell organelle   //  

shipping/receiving

department                 plasma membrane    

chief executive officer// nucleus

factory floor // cytoplasm

assembly line// endoplasmic reticulum

workers in the assembly line //ribosomes

finishing/packaging department //golgi apparatus

maintenance crew //lysosomes

support beams (walls, ceilings, floors) //cytoskeleton

power plant //mitochondria/chloroplasts

here's what each part of the cell does:

plasma membrane :

regulates what enters and leaves the cell; where cell makes contact with the external environment

nucleus :

controls all cell activity; determines what proteins will be made

cytoplasm :

contains the organelles; site of most cell activity

endoplasmic reticulum:

where ribosomes do their work

ribosomes :

build the proteins

golgi apparatus :

prepares proteins for use or export

lysosomes :

responsible for breaking down and absorbing materials taken in by the cell

cytoskeleton :

maintains cell shape

mitochondria/chloroplasts :

transforms one form of energy into another

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this
