Question 1: Compare and contrast the different metabolic pathways used by cells to generate ATP, illustrating your answer with a suitable table or diagram. Include in your answer discussion of the metabolic adaptations that occur in cells as they respond to changing internal and external environmental conditions.

Suppose the concentration of glucose inside a cell is 0.4 mM and the cell is suspended in a glucose solution of 0.03 mM. Part A What would be the free energy change, in kJ/mol, for the transport of glucose from the medium into the cell? Assume T= 37°C. Express your answer with the appropriate units.

Describe the process of cellular respiration, from the introduction of a glucose molecule into the cytoplasm to the production of the final ATP made from energy contained within that glucose molecule.

Imagine a scenario where a person is deprived of oxygen for a period of time. Answer the following questions as it relates to the aerobic cellular respiration reactions that occur in the mitochondria. Be specific in your answers and thoroughly explain. (Don't say fermentation will happen. It would likely, but focus on the mitochondrial reactions.)  Answer the following questions. These are 4 separate questions. Give an answer and explanation for each question.  1. Explain what would directly happen in the electron transport chain if oxygen is not present. 2. Based on #1, how would this affect NADH and FADH2?  3. What would be the direct effect of this in the intermembrane space?  4. If #3 happens, how will that affect what ATP synthase does?
