What type of ion channels in the membrane of neurons open or close in response to a neurotransmitter binding to its receptor

An ion channel in the membrane of neurons which <u>open or close</u> in response to a neurotransmitter that binds to its receptor is called:  ligand-gated channel.

<h3>What is an action potential?</h3>

An action potential can be defined as a sudden, fast change in electrical (voltage) potential with respect to the transmission of an impulse to a receptor, across a cellular membrane such as:

  • A nerve cell
  • A muscle cell

<h3>What is a neuron?</h3>

A neuron is a nerve cell that is saddled with the responsibility of transmitting electrical impulses down an axon across a cellular membrane of the body of a living organism through an action potential.

In Science, a ligand-gated channel is a type of ion channel in the membrane of neurons which <u>open or close</u> in response to a neurotransmitter that binds to its receptor.

Mnenie [13.5K]

Answer:

A homozygous recessive pea plant would have genotype rr and the heterozygous plant would have genotype Rr. So after the crossing between these two individuals occurs the two offspring produced would be heterozygous and the other two would be homozygous recessive.                    

                                      R    r

                                r   Rr   rr

                                r    Rr   rr

Therefore the genotype ratio would be 1:1 and the phenotypic ratio would also be 1:1 in the F1 generation because half would be round and half would be wrinkled.

The resolving power of the earliest electron microscopes was at least ten times higher than that of the light microscopes, mainl
ki77a [65]

The resolving power of the earliest electron microscopes was at least ten times higher than that of the light microscopes, mainly because the wavelength of electrons is much shorter than the wavelength of light.

The electron microscope uses a beam of accelerated electrons to magnify the object whereas the light microscope uses visible light for this purpose. Unlike the light microscope, the electron microscope uses electromagnets as lenses.

The magnification of the electron microscope is much higher as compared to the light microscope and it produces high-resolution images. However, the Specimen preparation of an electron microscope takes several days while the Specimen preparation of the light microscope takes only a few minutes.

Humans deplete the most resources when
Studentka2010 [4]

Answer:

Resource depletion is the consumption of a resource faster than it can be replenished. Natural resources are commonly divided between renewable resources and non-renewable resources (see also mineral resource classification). Use of either of these forms of resources beyond their rate of replacement is considered to be resource depletion. The value of a resource is a direct result of its availability in nature and the cost of extracting the resource, the more a resource is depleted the more the value of the resource increases. There are several types of resource depletion, the most known being: Aquifer depletion, deforestation, mining for fossil fuels and minerals, pollution or contamination of resources, slash-and-burn agricultural practices, Soil erosion, and overconsumption, excessive or unnecessary use of resources.

Resource depletion is most commonly used in reference to farming, fishing, mining, water usage, and consumption of fossil fuels. Depletion of wildlife populations is called defaunation.
