unlike at the taste. By adding flavorings‚ it can be used by everyone in the family. D. Definition of Terms • Sodium Bicarbonate – Baking Soda • TRPM8 – Transient receptor potential cation channel subfamily M member 8 also known as the cold and menthol receptor 1‚ is a protein. TRPM8 is an ion channel‚ upon activation it allows the entry of Na+ (sodium) and Ca2+(calcium) ions to the cell that leads to depolarization and the generation of an action potential. This eventually

Prior to begin the experiment‚ preparation for some solutions is required to enhance the lab performance. The solutions needed are standardized potassium bromate‚ standardized sodium thiosulfate‚ and starch indicator. First‚ to prepare a starch indicator‚ pulverize 1g of soluble starch and add 15mL of water to make it as a paste-like substance. Dilute it with about 500mL of boiling water‚ and continue to heat until the mixture becomes clear. Cool it to room temperature and save it into a stoppered

Clostridium Difficile People getting medical care can catch serious infections called healthcare-associated infections or HAI’s. One type of HAI which is caused by the germ Clostridium Difficile or C-Diff. In 2015 it was estimated almost half a million infections in the United Ststes‚ and 29‚000 died within 30 days of the initial diagnosis. Those most at risk are older adults‚ who take antibiotics and also get medical care. The CDC provides guidelines and tools for the healthcare population to help

must regulate is water; water is everywhere in our body and its balance is essential for proper body function. A very carefully regulated process is solute concentration. If there is a sudden increase in water which enters the extracellular fluid‚ sodium ions will then contribute less to the extracellular solute concentration as the ratio between water and solute has now changed. Osmolality is the amount of solute in a kilogram‚ hence the osmolality in the extracellular space has also decreased.

They are very reactive metals and do not occur freely in nature. Alkali metals are malleable‚ ductile‚ and are good conductors of heat and electricity. Alkali metals can also explode if they are exposed to water. The Alkali metals are: lithium‚ sodium‚ potassium‚ rubidium‚ cesium‚ and francium. Lithium The mineral petalite‚ which contains lithium‚ was discovered by a Brazilian scientist named Jose Bonifacio towards the end of the 18th century. Then in 1817‚ lithium was discovered by Johan August

difference in charge is continued by three factors. Firstly‚ in the cell membrane‚ there are sodium potassium ‘pumps’ crossing the membrane which are proteins that bring 2 potassium ions into the cell‚ for every 3 sodium ions it pumps out. As well as this‚ there are protein channels which allow potassium ions in the cell to flow out via facilitated diffusion. Potassium diffuses out the cell much more readily than sodium diffuses in. Lastly there are many negatively charged organic anions such as some amino

Similar to potassium‚ sodium is a major mineral‚ however‚ unlike potassium which maintains fluid and electrolyte balance inside the cell‚ sodium is a major part of the body’s fluid and electrolyte balance system because it is the chief ion used to maintain the volume of fluid outside cells. Sodium also helps maintain acid-base balance and is essential to muscle contraction and nerve transmission. The DRI recommended intakes for sodium for adults ages 19 to 50 years old is 1‚500 milligrams per day

citrate and sodium carbonate were mixed together‚ then the products were filtered out as so only the precipitate remained. The filtered paper was then dried and the mass of the precipitate in the experiment divided by the theoretical mass of the precipitate from the calculated gave the percent yield. The percent yield that was acquired is about 69.1%. The chemical reaction that took place was that sodium displaced calcium in a solution of calcium nitrate‚ and that calcium displaced sodium in a solution

Case Study: Newsflash! Transport Proteins on Strike! 1. What is the meaning behind the PHOSPHOLIPIDS’ chant? Phospholipids make up most of the cell membrane‚ in a phospholipid bilayer. Phospholipid molecules form two layers‚ with the hydrophilic (water loving) head facing the extracellular fluid and the cytosol (intracellular) fluid‚ and the hydrophobic (not water loving) tails facing one another. The cell membrane is constructed in such a way that it is semipermeable‚ and allows oxygen

In this experiment‚ several different compounds are being worked with – potassium iodide‚ lead (II) nitrate‚ acetic acid and sodium bicarbonate. The purpose of this experiment is to determine whether or not a reaction has taken place using qualitative and quantitative analysis. Procedure Part 1 - Qualitative observations of both potassium iodide and lead (II) nitrate were
