Evolution: Energy Pathways in the Different Domains of Life

APBIO-TAPPNL

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.
