Hints & Solution
(b) Coacervate is an aggregate of macromolecules such as proteins, lipids and membrane, and contain enzymes that are capable of converting substance such as glucose into more complex molecules, such as starch. Coacervate droplets arise spontaneously under appropriate conditions and may have been the prebiological systems from which living organisms originated.
