What is a electrical current is produced when charges are accelerated by an electrical field to move to a position of potential energy that is?
potential energy
WhatConversion of a stimulus into a generator potential is?
Receptor potential, a type of graded potential, is the transmembrane potential difference of a sensory receptor. A receptor potential is often produced by sensory transduction. It is generally a depolarizing event resulting from inward current flow. The influx of current will often bring the membrane potential of the sensory receptor towards the threshold for triggering an action potential. A receptor potential is a form of graded potential, as is a generator potential. It arises when the receptors of a stimulus are separate cells. An example of this is in a taste bud, where taste is converted into an electrical signal sent to the brain. When stimulated the taste bud triggers the release of neurotransmitter through exocytosis of synaptic vesicles from the presynaptic membrane. The neurotransmitter molecules diffuse across the synaptic cleft to the postsynaptic membrane. A postsynaptic potential is then produced in the first order neuron, and if the stimulus is strong enough to reach threshold this may generate an action potential which may propagate along the axon into the central nervous system
Where is the energy form a light bulb produced?
in a power station, which usually converts chemical potential energy into electrical energy, which supplies potential difference and drives current.
How is produce current?
Current is created when electrical charges move through a wire or other conductor. It can be produced by rotating magnetic fields (as in a generator) or by connecting a source of higher electrical potential (charge) to one of lower electrical potential, which can cause the movement of charges from one point to another.
What do pacinian corpuscles detect?
They are mechanoreceptors that detect pressure, and are found in the skin and also in joints and tendons. Naked nerve endings lie in the centre of the corpuscle surrounded by concentric layers of connective tissue separated by viscous gel (looks a little bit like an onion!).Mechanical stimuli are converted into electrical impulses as follows:Transduction occurs - the production of a small receptor potential of about 1mV across the receptor membrane when pressure is applied.The receptor potential is produced by deformation of the receptor membrane, which interferes with ion channels embedded in the membrane and causes leaks, allowing an influx of sodium ions.A generator potential is produced and an impulse is generated at the first node of ranvier. Electrical impulses are transmitted along the neurone.The presence of gel-filled lamellae in the Pacinian corpuscles provides a mechanical filter of the stimulus. If pressure is applied rapidly the membrane of the corpuscle is deformed for a few milliseconds until the gel flows and the membrane resumes its normal shape. If pressure is applied slowly the gel flows away from the stimulus so the membrane is not deformed, and no receptor potential is generated. The greater the pressure applied to the corpuscle, the greater the receptor potential. Once the pressure reaches a critical size (te threshold) an action potential is triggered.
How many volts are produced in one cup of water?
essentialy zero. Voltage is the measure of difference of potential. unless something is done to charge the water its going to have the same electrical potential as everything around it.
How is potential energy converted to electrical energy?
Assuming that you are referring to electrical energy produced by power plants,where the source is water, the difference of potential represented by the difference of level, which falls down from the dam, a huge amount of water force the rotation of big turbines that generates alternating current.
When new cells are produced how will crossing over affect how they appear?
I KNOW When new cells are produced, how will "crossing over" affect how they appear?
Which membrane potential occurs because of the influx of Na plus through chemically gated channels in the receptive region of a neuron?
An excitatory postsynaptic potential, a type of graded potential, occurs because of the influx of Na+ through chemically gated channels in the receptive region, or postsynaptic membrane, of a neuron. Graded potentials are generated by chemically gated channels, whereas action potentials are produced by voltage-gated channels.
What is the difference between the gametes produced without corssing over and the ones produced with crossing over?
Gametes produced by crossing over are called non parental and possess more genetic variations as compared to those produced with out crossing over which possess much less genetic variations.
What is the energy produced by electrical charges called?
electrical energy
Is current produced with out potential difference?
No.
