Step by step
Solved in 2 steps
- Both prokaryotic and eukaryotic organisms carry out some form of glycolysis. How does ha fact support or not support the assertion that glycolysis is one of the oldest metabolic pathways?When oxygen is not available, yeast cells can still do glycolysis to produce ATP. Under these conditions, why would yeast cells also need to do fermentation?Fermentation in yeast cells generates ethanol. is this statement true or false?
- why alcoholic fermentation is not the most efficient process for producing ATP?Fermentations yield only a fraction of the energy available from the complete combustion of glucose. Why is a relatively inefficient metabolic pathway so extensively used?In aerobic oxidation, oxygen is the ultimate oxidizing agent(electron acceptor). Name two common oxidizing agents inanaerobic fermentation.
- Fermentation permits the continued extraction of energy from glucose in the absence of oxygen. If glucose catabolism is anaerobic, why is fermentation necessary for glycolysis to continue?how does the fermentation help the process of glycolysis continue in the absence of oxygenWhy is there such a large range of ∆G for the second step of glycolysis?
- for aerobic respiration, anaerobic respiration and fermentation, briefly explain How are they processes similar?The pyruvate →lactate reaction in animals is reversible, but the pyruvate → ethanol fermentation in yeast is irreversible. Explain.Is it possible to perform aerobic fermentation using yeast? Explain why and compare the fermentation pathway with anaerobic pathway.
