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

1 answer:

4 0

An ion channel in the membrane of neurons which open or close 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 open or close in response to a neurotransmitter that binds to its receptor.

31. The data in the accompanying graph show evidence of disease in the human body. D 38 - - E Body Temperature (°C) 377 А IDOT B

shepuryov [24]

Homeostasis keeps the organism in a dynamic equilibrium within the homeostatic range. A disruption in dynamic equilibrium is indicated by the temperature change between point C and D. Option C is correct.

<h3>What is homeostasis?</h3>

Homeostasis is the organism's capacity to keep the body in constant internal equilibrium, even when the external environment is oscillating.

Homeostasis is critical to keep the correct internal functioning of the body.

Different functions -blood pressure, body temperature, respiratory rate, and blood glucose levels, among others- are kept in a restricted range around a reference point, even though external conditions may be changing.

When a sudden change occurs in the internal functioning that disturbs this equilibrium, the organism counters it back by negative or positive feedback.

<h3>Graph interpretation</h3>

In the exposed graph we can see,

The restricted range of homeostasis at a constant temperature around 37ºC.

Six reference points (A-F) withing 12 hours.

Dynamic equilibrium is kept in the range of homeostasis around 37ºC, excepting for point D that reaches 38ºC.

The references point A, B, and C suggest that during the first 10 hours, approximately, the body was in equilibrium.

A change in the internal functioning broke the equilibrium, rising temperature to 38ºC, out of the homeostatic range.

The organism took the internal values to their original state, and at points E and F, the organism was in equilibrium again.

A disruption in dynamic equilibrium is indicated by the temperature change between point C and D.

Vitek1552 [10]

The clip that provides an example of a match cut is two cars one night. You are to compare between Death to the Tinman and Two Cars One Night. Between the two, only two cars and one night showed a sense of continuity between shots in terms of graphic content, eyelines and action of a match cut.
