Q Question 1 0.5 / 0.5 pts Please match each term related to energy and metabolism with its best definition. Question 2 0.5 / 0.5 pts Which of the following electron donor/electron acceptor pairs would generate the most energy for a bacterial cell? Question 3 0.5 / 0.5 pts E. coli is capable of aerobic respiration, anaerobic respiration, and fermentation. Imagine you inoculate three test tubes with the same number of E. coli cell, add the same amount of glucose to each, and set each up with the appropriate conditions to each individually support one of these forms of metabolism, e.g., tube A supports aerobic respiration, tube B supports anaerobic respiration, and tube C supports fermentation. Following growth, you measure the optical density (absorbance) of each tube using a spectrophotometer. Which of these three tubes should show the highest density of E. coli cells? PartialQuestion 4 0.17 / 0.5 pts A friend asks you to summarize the benefits of central metabolic pathways to a cell. You would most correctly choose which of the following options?
