Glycolysis is a metabolic process that is done by all cells. However, not all cells make use of another metabolic process called the Krebs cycle. What does this tell you about the evolution of these processes?
A. As a metabolic process, glycolysis likely evolved prior to the Krebs cycle B. As a metabolic process, the Krebs cycle likely evolved prior to glycolysis C. Both the Krebs cycle and glycolysis likely evolved at the same time Clarify Question What is the key concept addressed by the question? What type of thinking is required? Gather Content What do you already know about evolution and time? What other information is related to the question?
