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

nonfebrile controls. The osmolality in febrile children with convulsions was 3.8% (P < 0.01) and without seizures 3.5% (P < 0.01) lower than in nonfebrile nonconvulsive children. The changes in CSF sodium concentration‚ and to a lesser extent potassium and chloride concentrations‚ paralleled those of CSF osmolality. A positive correlation was observed between the CSF and serum osmolatities (r = 0.73‚ P < 0.0001)‚ and sodium concentrations (r = 0.63‚ P < 0.0001). A negative correlation between

divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal. Metals: Part - I Physical Properties of Metals:- Hardness:- Most of the metals are hard‚ except alkali metals‚ such as sodium‚ potassium‚ lithium‚ etc. Sodium‚ potassium‚ lithium etc. are very soft metals‚ these can be cut using knife. Strength:- Most of the metals are strong and have high tensile strength. Because of this big structures are made using metals‚ such as copper and iron. State:-

or concentration of the ion in the compound. Some colors are very weak and are easily overpowered by stronger colors. For instance‚ the presence of a potassium ion in a compound will color a flame violet. But on the other hand‚ even trace amounts of sodium ions in a compound produce a very strong yellow flame‚ often times making the potassium ion very difficult to detect. To counteract the effects of any sodium impurities‚ one can view the flame through a piece of cobalt blue glass. The cobalt

glucose along with water and electrolytes (esp. sodium and potassium). The fatty acids are converted into ketone bodies by the liver. Ketone bodies are acidic; their accumulation in the circulation due to lack of insulin leads to metabolic acidosis. 2. What are the commonly seen blood glucose levels? 300-800 mg/dL but some can get as high as 1‚000 mg/dL 3. What fluid and electrolyte disturbances commonly occur and why? Soidum and potassium due to the amount of water loss 4. What acid-base disturbances

Decomposition of Potassium Chlorate Hypothesis: Potassium chlorate decomposes into potassium chloride and oxygen gas‚ which means that when the glowing splint is inserted into the test tube‚ the flame will have enough fuel to fully reignite the splint. When the manganese dioxide is added‚ this will increase the rate of the production of oxygen in the reaction‚ without affecting the state of the manganese oxide.
