Question

Evolutionary biologists maintain that glycolysis is a metabolic pathway that evolved on earth prior to the divergence of life on planet Earth into different domains.
Which of the following statements best supports this hypothesis?

• A. The process of glycolysis, with few molecular modifications, is used by all cells on the planet regardless of the domain to which they belong.
• B. Glycolysis is the only metabolic pathway the does not use or require the presence of oxygen.
• C. The process of glycolysis is used by all eukaryotic organisms from all Domains and Kingdoms.
• D. The enzymes used in the process of glycolysis are found in the cytosol of cells rather than in a membrane-enclosed organelle.

Answer 1

The correct option is A The process of glycolysis, with few molecular modifications, is used by all cells on the planet regardless of the domain to which they belong.

Evolution of glycolysis. The first prokaryotic did not have access to a large supply of oxygen in the early Earth atmosphere, so they likely had to use glycolysis to create ATP. Without glycolysis living organisms would not have the ability to engage in fermentation or begin the process of Cellular Respiration

So, the correct answer is 'the process of glycolysis, with few molecular modifications, is used by cells on the planet regardless of the domain to which they belong'
