Ion

nerves cells that make up the nervous system are excitable cells, as they have the ability to produce an electric current to formrom an action potential from using a concentration gradient of ions across their membrane (Sherwood, 2013). The current generated by the flow of sodium (〖Na〗^+) and potassium ( K^+)ions is called an action potential and occurs in three steps: depolarization, repolarization, and hyperpolarization. First, a membrane potential 〖(V〗_m) is established by creating a…

optimal rate. On average, it would take around 4 hours for the Tungsten filament to erode which would often happen at the end of a 2nd session of synthetisation, with each session lasting 2 hours. It is better to not bombard the filament with positive ions for longer as this would cause the filament to erode at an even faster…

wondering what inorganic and organic compound are. An inorganic compound is any compound that is not organic while an organic compound is any member of large gaseous, liquid, or solid chemical compounds whose molecules contain carbon. A polyatomic ion compound are made up of two or more atoms bonded together and a metal. A binary compound is a chemical compound that contains exactly two different elements. These two differ because polyatomic are made up of two or more atoms while binary…

superabsorbent pillows to identify a quantitative trend that can efficiently clean-up spills of heavy metal ion solutions. This investigation has value to companies or people they want to find a way to efficiently clean-up spills of toxic metals in bodies of waters that could damage species in and around these waters. Experimental Design and Procedure In order to efficiently clean-up spills of heavy metal ion solutions, we implemented an experimental design by having the amount of sodium…

sounds crazy, but it's true! This is because salt water is a good conductor of electricity. Salt molecules are made of sodium ions and chlorine ions. (An ion is an atom that has an electrical charge because it has either gained or lost an electron.) When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity through water. What happens is the solution of the water and the salt is transformed…

If the solution has more hydrogen ions, it is an acidic solution, and if the solution has more hydroxide ions, it is a base (636). Acids and bases can be strong or weak. Strong acids are able to conduct electricity, and all the HCl molecules in the solution can be ionized completely (644). Weak acids produce fewer ions, and therefore do not conduct electricity well (645). Strong bases can dissociate completely into metal ions and hydroxide ions, while weak bases can only ionize partially…

through the membrane. Ion channels are pore-forming proteins also referred to as cell-membrane bound receptors. They are mostly found on synaptic structures and are involved in neuronal activities. Ions pass down their electrochemical gradient through ion channels without the requirement of ATP or metabolic energy. Ion channels are an important component of the nervous system as activation of these channels by neurotransmitters mediate conduction across nerve synapses. Ion channels also play a…

combine with the diphenylmethyl cation. At the beginning, although chloride ion is a better nucleophilic reagent than water, its concentration is so small that it can be neglected, while the concentration of water is so large that it does not appear in the rate formula as the solvent. During the process of the reaction, the concentration of chloride ion increases gradually and the effect of the competition between chloride ion and water becomes important enough to be taken into consideration in…

contain zinc. Zinc can also be consumed by taking a supplement. A deficiency in zinc can cause growth retardation, delayed sexual maturation, eye and skin lesions, hair loss, and an increased risk of illness and infection. Zinc is one of the many ions that function as an enzyme cofactor. Every chemical reaction in the body requires an enzyme. Enzymes are biological…

Epilepsy is a neurological disorder caused by malfunctioning nerve cells within the brain and nervous system. Juvenile myoclonic epilepsy (JME) is a variation of this disorder, appearing mainly in children ages 12 to 18. This disorder is caused when the ion channels in the nerves cells that regulate cell communication are not produced in the correct amount. When this happens, signaling is not controlled and leads to overstimulation. Some symptoms resulting from this include mild muscle jerks, or…
