When mixed with water,why do phospholipids spontaneously form membranes?
A. Phospholipids do not spontaneously form membranes when mixed with water.
B. Phospholipids have hydrophilic phosphate groups that are attracted to water and hydrophobic fatty acid tails that avoid water.
C. Phospholipids have hydrophilic phosphate groups that are attracted to their hydrophobic fatty acid tails.
D. Phospholipids are capable of violating the second law of thermodynamics.
E. Phospholipids have hydrophilic fatty acid tails that are attracted to water and hydrophobic phosphate groups that avoid water.
Answer:
The answer is B. A phospholipid is characterized as having a hydrophilic region (the phosphate) and a hydrophobic region (the long chain fatty acids). whe put into H2O the phosphate groups will orientate themselves towards the H2O while the fatty acids will orient themselves away from the H2O thus forming membranes or miscelles.
