The main ion responsible for depolarizing the sarcolemma is sodium (Na+).
Chemically gated Na+ ions.
Chemically-gated channels
An action potential starts when sodium channels in a neuron end open and sodium ions rush is, depolarizing the neuron's membrane.
Yes, many cells have chemically gated ion channels. This means that the channel requires a specific chemical to open the gate and allow for things to pass through the membrane
chemically gated channels
Chemically gated Na+ ions.
The sarcoplasmic reticulum are the membranous interconnecting channels and sacs that surround and run parallel to the myofibrils.
Chemically-gated channels
An action potential starts when sodium channels in a neuron end open and sodium ions rush is, depolarizing the neuron's membrane.
GABA chemically gated channels and chloride nongated channels
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.
Yes, many cells have chemically gated ion channels. This means that the channel requires a specific chemical to open the gate and allow for things to pass through the membrane
chemically gated channels
causes chemically gated sodium channels to open
Chemically Gated Channels.
It results from the opening of voltage-gated sodium ion channels, causing an influx of sodium ions (influx of positively-charged ions), depolarizing the neuronal membrane.
