4. (a) duced in large part by cells in the liver via a specialized metabolic program called gluconeogenesis. Gluconeogenesis is often incorrectly described as "glycolysis in reverse". Compare and contrast the enzymes and reactions that drive gluconeogenesis and glycolysis. Several mammalian tissues rely on a steady supply of glucose in the bloodstream pro-
The cell senses ATP is not being produced. What immediate effect will this have on the rate of glycolysis occurring in the cell? What will happen to the levels of pyruvate? A. Glycolytic rates will decrease: pyruvate levels will decrease B. Glycolytic rates will increase: pyruvate levels will increase C. Glycolytic rates will increase: pyruvate levels will decrease D. Glycolytic rates will decrease: pyruvate levels will increase 2. How will the cell shift its metabolic processes in response to the level of pyruvate and in order to produce ATP? A. It will shift from aerobic respiration to fermentation B. It will shift from aerobic respiration to anaerobic respiration C. It will continue with aerobic metabolism using oxygen in the cytosol to make ATP D. It will shift from anaerobic respiration to fermentation 3. Some of the symptoms the patient is experiencing are caused by acid-base imbalances in the extracellular fluid. Why would the patients blood become more acidic over a…
Under anaerobic conditions, skeletal muscle cramps up and is unable to relax. Based on what you know about ATP production under anaerobic conditions, explain why skeletal muscle remains contracted.

In order to improve their recovery after an intense work out or competition, many high-level athletes use "cool downs" to rapidly slow down their movements, by eating a snack, and breathing deeply. What choice below accurately explains how these steps aid cellular respiration? A. Eating a snack takes in more energy which converts to sugar needed by the body to produce oxygen to begin cellular respiration. B. Cooling down in this way they are able to take in oxygen and sugar, which allows their cells to produce energy through cellular respiration. C. Breathing deeply and eating a snack releases more carbon dioxide and sugar, which leads to more energy for cellular respiration to begin. D. Cooling down in this way they are able to take in carbon dioxide and water which allows their cells to produce energy through cellular respiration. 5.
If glucose was no longer available, citric acid cycle activity would: a. decrease b. increase c. remain the same

Carries glucose into the muscle cellb. signals the muscle cell to take up glucose c. signals the synthesis of glucose in the liver d. carries lactate from the muscle to the liver 2.In the fasting, state, the Liver helps maintain a normal level of blood glucose by: a. Making ketones and storing them for later.b. stopping glycolysis and using alternative fuels for energyc. speeding up glycolysis because it needs energy to make glucose d. Beginning glycogenesis to build up glucose storage
