<span>Creationists don't seem to understand that evolutionary theory has become the cornerstone of modern biology. As a biology student, everything I learn about is supported by the fact that all life on earth is related. Evolutionary theory provides the "glue" that holds modern biology together and it is not only the best, but the only scientific explanation which can provide legitimate answers to numerous scientific observations (like the structure of human chromosome #2, for instance). And I'm not even beginning to talk about the importance that the theory has had on modern medicine, fighting diseases, understanding how viruses evolve resistance, etc.</span>
Answer:
b) glycolisis
Explanation:
Glycolisis precedes the Krebs cycle and can take place under aerobic or anaerobic conditions. Under aerobic condition, energy is directed towards the Krebs cycle in the form of piruvate and NADH to create more ATP. Under anaerobic conditions piruvate does not enter the Krebs cycle and it is oxidized to produce lactate.
