You need more context to answer this.
Answer:
The (Receptive) segment includes both dendrites and the cell body, which are the regions of the neuron that receive stimuli to excite the neuron. Channels in this region are (Gated chemically) ; no significant numbers of (Voltage gated) channels are present.
• The (Initial) segment is composed of the axon hillock. This segment contains voltage-gated channels.
• The (Conductive) segment is equivalent to the length of the axon. It contains voltage-gated channels.
• The (Transmission) segment includes the synaptic knob and contains voltage-gated channels and (Pumps) .
I believe it results to a conformation change that moves the Na+ binding site to the inside of the cell. ATP hydrolysis involves the release of chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate.For example in muscles. The process of moving sodium and potassium ions across the cell membrane is an active transport process involving the hydrolysis of ATP to provide the necessary energy. It involves an enzyme referred to as Na+/K+ ATPase.
Answers:
thorium-234
Explaination:
Isotopes are defined as the variants of a particular chemical element obtained by radioactive decay which makes it differ in neutron number and nucleon number but have the same number of protons in each atom.
Uranium-238 produces thorium-234 by alpha decay. alpha particle is a helium nucleus which carry 2 neutrons andn 2 protons with the mass number 4. In alpha decay, nucleus emits alpha particles which tranforms or decay into an atom with a mass number 4 less and an atomic number 2 less.
The equation for alpga decay is attached below:
Hence, the isotope is thorium-234 .
