Evolution: Energy Pathways in the Different Domains of Life


Evolutionary biologists maintain that glycolysis is a metabolic pathway that evolved on earth prior to the divergence of life on Earth into different domains.

Which of the following statements BEST supports this hypothesis?


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


Glycolysis is the only metabolic pathway the does not use or require the presence of oxygen.


The process of glycolysis is used by all eukaryotic organisms from all domains and kingdoms.


The enzymes used in the process of glycolysis are found in the cytosol of cells, rather than in a membrane-enclosed organelle.
