Question

13) The last time point was taken at S0 hours... from what's shown on the growth curve at that time, can you describe what the bacteria were doing in the flask of liquid media at 5O hours? What was their environment like inside the flask? (4 points) 14) In the intestine, E. coli grows best aerobically. Draw a flowchart of the metabolic pathways necessary to completely oxidize glucose and produce maximum ATP (-38ATP max). (you don't need to draw the PATHWAY, just name the pathway but put the pathways in the order in which they are used). (3 points) Glucose- 15) Once oxygen runs out, the bacterium shifts its metabolism so that fewer ATPs are produced (10- 23ATP max) as long as there is nitrate (NO3) available. Draw the flow of pathways again for this scenario. (3 points) Glucose- -10-23APTS time producing only 2 ATPs per glucose. Draw the flow of pathways under this situation. (3 points) Glucose 17) Which one of the individual cycles/pathways above is MOST important for ATP production? (3 points) 18) Which one of the individual cycles/pathways is MOST important for harvesting electrons from food? (3 points)

Explanation / Answer

14) glucose--> glycolysis--- Krebs cycle--- electron transport chain---38 Atp

16) Glycolysis--anerobic respiration

17) glycolysis

18) Krebs cycle
