Question

Imagine a new type of cell was discovered on Mars in an organism growing in benzene, a nonpolar liquid. The cell had a lipid bilayer made of phospholipids, but its structure was very different from that of our cell membranes.*Part A:* Describe what might be a possible structure for this new type of membrane.A.)This membrane would have the polar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophilic interior.B.) This membrane would have the nonpolar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophilic interior.C.) This membrane would have the nonpolar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophobic interior.D.) This membrane would have the polar groups on the two surfaces facing the nonpolar solvent, and it would have a hydrophobic interior.*Part B:* *What might be characteristic features of the phospholipid head groups?A.)The phospholipid head groups would likely have equal numbers of hydroxyl and amino groups that would pack well and not be bulky.B.)The phospholipid head groups would likely have equal numbers of positively and negatively charged groups that would pack well and not be bulky.C.)The phospholipid head groups would likely bind to each other with covalent bonds that would pack well and not be bulky.D.)The phospholipid head groups would likely bind to each other with hydrogen bonding that would pack well and not be bulky

Answer 1

Answer:

Part a : c is true, part b: c is correct

Explanation:

Since this new cell can grow in a non polar liquid, that mean that need to be surround with this kind of molecules, and inside will be similar because if not the water will never get out from the cell.

The phospholipid will form a lipid bilayer and since the external and the inner structure is a non polar environment, the bonding among the lipids will be covalent nature so it can flow in a non polar surrounding.
