- Which of the following is a true distinction between fermentation and cellular respiration?
- Cells do not catalyze carbon dioxide because
- When electrons flow along the electron transport chains of mitochondria, which of the following changes occur?
- The final electron acceptor of the electron transport chain that functions in aerobic oxidative phosphorylation is
- In mitochondria, exergonic redox reactions
- Which metabolic pathway is common in both fermentation and cellular respiration of a glucose molecule?
- The immediate energy source that drives ATP Synthesis by ATP synthase during oxidative phosphorylation is
- Even though plants carry on photosynthesis, plant cells still use their mitochondria for oxidation of pyruvate. When and where will this occur?
- What is the purpose of beta oxidation in respiration?
- Phosphofructokinase is an allosterically enzyme that catalyzes the conversion of fructose-6-phosphate to fructose-1, 6-bisphosphate, an early step of glycolysis. In the presence of oxygen, an increase in the amount ATP in a cell would be expected to
- Phosphofructokinase is an important control enzyme in the regulation of cellular respiration. Which of the following statements describes a function of phosphofructokinase?
- You have a friend who lost 7kg of fat on a low carb diet. How did the fat leave her body?
- When muscle cells undergo anaerobic respiration, they become fatigued and painful. This is now known to be caused by
- When muscle cells are oxygen deprived, the heart still pumps. What must the heart cells be able to do?
- Muscle cells, when an individual is exercising heavily and when the muscle becomes oxygen deprived, convert pyruvate to lactate. What happens to the lactate in skeletal muscle cells?
- Why is glycolysis considered to be one of the first metabolic pathways to have evolved?
- Glycolysis is thought to be one of the most ancient of metabolic processes. Which statement supports this idea?
- An organism is discovered that consumes a considerable amount of sugar, yet it does not gain much weight when denied air. Curiously, the consumption of sugar increases as the air is removed from the organisms environment, but the organism seems to thrive even in the absence of air. When return a normal air, the organism does fine. Which of the following best describes an organism?
- One function of both alcohol fermentation and lactic acid fermentation is to
- In alcohol fermentation, NAD+ is regenerated from NADH during which of the following?
- In the absence of oxygen, yeast cells can obtain energy by fermentation, resulting in the production of

- Which metabolic pathway is common to both cellular respiration and fermentation?
- Which of the following occurs in the cytosol of a eukaryotic cell?
