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? Choose Answer Do you have all necessary information to determine the relative importance of glycolysis and the Kreb’s cycle? Reflect on Process Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
In 1937, two German biochemists published a paper proposing the following reactions as part of the glucose oxidation. citrate isocitrate -ketoglutarate succinate fumarate malate oxaloacetate
Adding succinate, fumarate, or malate to thin slices of tissue increased oxygen consumption, supporting the hypothesis that these molecules are intermediates in the process. However, a puzzling observation was that intermediates were still present in the reaction mixture at the end of the experiment. If they are intermediates, then they should be consumed as the next product in the pathway is formed. What explains this observation? A. Succinate, fumarate, and malate are not reactants but catalysts, and catalysts are not consumed in the process. B. Succinate, fumarate, and malate are constantly regenerated in the citric acid pathway. C. Succinate, fumarate, and malate increase metabolism and therefore oxygen consumption, but they are not directly part of the glucose oxidation pathway.
