A
A complex carbohydrate used for energy storage in plants
B
A catalyst that speeds up chemical reactions in living organisms
C
A simple, pre-cellular structure that exhibits some properties of life
D

Verified step by step guidance1
Begin by understanding the term 'protobiont'. In organic chemistry and biology, a protobiont refers to a simple, pre-cellular structure that exhibits some properties of life. These structures are considered precursors to living cells.
Protobionts are not complex carbohydrates, catalysts, or organic molecules forming the backbone of DNA. Instead, they are primitive structures that may have been involved in the origin of life.
Consider the properties that define life, such as metabolism, growth, and reproduction. Protobionts exhibit some of these properties, although they are not fully living organisms.
Protobionts are thought to have formed spontaneously from organic molecules in the early Earth's environment, possibly through processes like self-assembly and encapsulation.
Reflect on the significance of protobionts in the study of the origin of life, as they provide insights into how simple organic molecules could evolve into complex living cells.
