Chapter 14, Problem 25A

Summary Introduction

To analyze:

The first step in the emergence of life from non-living matter.

Introduction:

Life on earth was evolved about 3.5 billion years ago. There are many theories of origin of life on earth. Some says it was started with the spark of electricity. Some says it was due to the molecular interaction and some other says life began in the deep sea.

Explanation of Solution

Most of the theories were true in sense of understanding the origin of life on earth from the microbes. They said the microbes evolve into the more complex organism with the time. However, the life evolves from non-living matter which includes the formation of macromolecules. Major macromolecules are carbohydrates, nucleic acid, proteins and lipids.

Conclusion

This concludes that the first step in the emergence of life is the formation of macromolecules.
