Vedclass · Answer

(A) Microspheres are spherical structures formed by the aggregation of proteinoids. Sydney Fox $(1950)$ demonstrated that heating a dry mixture of amino acids to $130^{\circ}C-180^{\circ}C$ results in the formation of proteinoids or polypeptides. When these are cooled in water,they form protenoid microspheres with a diameter of $1-2 \mu m$. These microspheres possess a membrane composed of lipids and proteins,which mimics the structure of modern cell membranes and represents a primitive form of protobiont.

In the origin of life,microspheres are the most primitive protobionts,which have a membrane of
