Question

Identify the incorrect statement about coacervates.

• A. Oparin speculated that a prebiont consisted of carbohydrates and proteins
• B. Miller introduced the term coacervates
• C. According to the modern theory of origin of life, coacervates are believed to be prebionts
• D. It is surrounded by a water film

Answer 1

The correct option is B Miller introduced the term coacervates

A coacervate is a spherical aggregation of lipid molecules. The hypothesis related to coacervates was proposed by Oparin.
Oparin introduced the term coacervates. Hence option b is incorrect.

According to the modern theory of origin of life, coacervates are believed to be protobionts. A protobiont is referred as an aggregate of abiotically produced organic molecules surrounded by non unit membrane. So option c is correct.

Coacervates consist of carbohydrate and proteins. It is surrounded by water film which acts as a barrier between coacervates and surroundings. They have the ability to take materials from surrounding and incorporates them into their structure. They have the ability to increase in size also. So option a and d are correct.
