Answer:
- flippases translocate lipids from outer (extracellular) leaflet to inner (cytosolic) leaflet,
- floppases, move phospholipids from inner (cytoplasmic) leaflet to outer (extracellular) leaflet, ABC transporter, move phospolipids across the lipid bilayer down the concentration gradient
- scramblases Not ATP-dependent, Activation may result in increased membrane lipid symmetry, translocate phosphatidylserine, preventing apoptosis and engulfment by macrophages,
Explanation:
Flipases are transportes that require energy for their functioning (ATP dependent) beause they move phospolipids across the lipid bilayer against the concentration gradient (from extracellular side to cytosolic side).
Floppases are ABC transporters, opposite than flippases (move phospholipids from the cytosolic side).
Scrablases are bidirectional transporters, responsible for asymmetry formation. It also enables exposure of phosphatidylserineon the outer leaflet when it is necessary.
The appropriate action that nurse should do first is to take
note of the signs that can be a suspect of nasogastric tube blockage and that
it is needed to instill about 30 ml of air in which will reestablish the
patency. Next step is to also take note that the opioids used can increase
nausea and abdominal detention and that it decreases peristalsis. The nurse
should tell the client and notify them that there will be no stool for several
days and that because of the surgery in which is also expected that there are
no bowel sounds to be produced.
Water, air, food. and heat.
The structure of the plasma membrane makes it selectively permeable, enabling it to regulate the transport substance into and out of the cell, such as
- small, non polar molecules are hydrophobic
- Polar molecules and ions are hydrophilic
- Polar molecules and ion usually pass with the help of protein
hope this helps
