An Experiment Mixed Oil (Lipids),organophosphate-Containing Detergent in Water,and Copper Ions

question 72

Multiple Choice

An experiment mixed oil (lipids) ,organophosphate-containing detergent in water,and copper ions to act as a catalyst for a chemical reaction.Membranes budded off of the oil in this mixture.Which of the following is a reasonable and possible explanation of the experimental results?

• A) The chemical reaction caused the organophosphates from the detergent to chemically combine with lipids from the oil to form phospholipids. The hydrophilic tails lined up toward each other with their hydrophobic heads pointing out toward the water; this configuration formed a phospholipid bilayer that pulled into a liposome.
• B) The chemical reaction caused the organophosphates from the detergent to chemically combine with lipids from the oil to form phospholipids with hydrophilic heads and hydrophobic tails. The hydrophobic tails lined up toward each other with their hydrophilic heads pointing out toward the water; this configuration formed a phospholipid bilayer that pulled into a spherical liposome.
• C) The copper ions permanently, chemically combined with the lipids to form phospholipids. The hydrophilic tails lined up toward each other with their hydrophobic heads pointing out toward the water; this configuration formed a phospholipid bilayer that pulled into a liposome.
• D) The copper ions permanently, chemically combined with the lipids and phosphates to form phospholipids. The hydrophilic tails lined up toward each other with their hydrophobic heads pointing out toward the water; this configuration formed a phospholipid bilayer that pulled into a liposome.
