Alexander Oparin hypothesized that living cells evolved from coacervates. What was the "boundary" material of the coacervates Oparin made, and how does this boundary differ from present day liposome membranes?
A. Oparin used a phospholipid bilayer to build the coacervates, it is the same as the bilayer found in present day liposomes.
B. Oparin's coacervates were surrounded by a tight skin of water molecules, the same as present day liposomes.
C. Oparin's coacervates were surrounded by carbohydrates and lipids, unlike present day liposomes which have a carbohydrate membrane only.
D. Oparin's coacervates were surrounded by a tight skin of water molecules; present day liposomes have a phospholipid bilayer for their membrane.
E. Starch was the main component in Oparin's coacervate boundry; liposomes also use mainly carbohydrates for their membrane.
D. Oparin's coacervates were surrounded by a tight skin of water molecules; present day liposomes have a phospholipid bilayer for their membrane.
