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

that requires the heart to pump harder than normal‚ and as a result‚ causes the heart to enlarge (Stöppler‚ n.d.). Congenital heart defects can cause the heart to pump harder by being able to change the flow of blood through the heart (Mayo Clinic Staff‚ 2011). Arrhythmia and prolonged anemia are also conditions that can cause the heart to pump harder and lead to cardiomegaly (Stöppler‚ n.d.). People with arrhythmia have an abnormal heart rate and lack a heart that pumps blood effectively. This forces

precision is the volume of detail something delivers. Society depends on accuracy and precision in many places. One instance is the gas pumps. The gas pump can show accuracy when the gas is flowing‚ but this is not a precise measurement of how much gas is pumping through the pumps. Gas pumps must not only know how much gas is pumping through the pumps but also how precise the measurement of gas pumped. The gas companies need to know how much is pumped so that the company can charge the right

for Destin Brass’s Valve‚ Pumps and Flow Controllers in efforts to determine whether the company’s current costing system is in fact enhancing profitability. If you take a look at Exhibit 2‚ you can see the new costing Activity-Based Costing (ABC) System that we are proposing should be used to cost and price your products. The new costing system estimates the cost of the valves to be $37.75‚ the pumps to be $48.87‚ and the Flow Controllers to be $100.57.

therefore can detect if the wheel [or car] is entering a situation in which it may lock up. The valves control the pressure of the break by lowering it. On the other hand‚ the pump raises the pressure of the brake. Inside the car there is a controller‚ similar to a computer‚ which controls the speed sensors‚ the valves‚ and the pumps. Depending on the number of channels and sensors in the specific system‚ there are many variations of ABS. A four channel‚ four sensor ABS is the best because all four

its working and uses. A piston is a component of reciprocating engines‚ reciprocating pumps‚ gas compressors and pneumatic cylinders‚ among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. In an engine‚ its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. In a pump‚ the function is reversed and force is transferred from the crankshaft to the piston for
