From the point of view of early chemical evolution that preceded the origin of life on earth, the most important simple organic molecules formed were

A

sugars and amino acids

B

glycerol and fatty acids

C

puriness and pyrimidines

D

all of these

Text Solution

Verified by Experts

The correct Answer is:
D
The early inorganic molecules interacted and produced simple organic molecules such as simple sugars (e.g., ribose, deoxyribose, glucose, etc.), nitrogenous bases (e.g., purines, pyrmidines), amino acids, glycerol, fatty acids, etc. `CH_(4) +CO_(2)+H_(2)O to ` Sugars + Glycerol + Fatty acids
`CH_(4)+HCN+NH_(3)+H_(2)O to` Purines + pyrimidines
`CH_(4) +NH_(3)+CO_(2)+H_(2)O to` Amino acids
