Compare the number of ATP molecules required to produce one glucose molecule in photosynthesis (see figure 5.9)

Question:

Compare the number of ATP molecules required to produce one glucose molecule in photosynthesis (see figure 5.9) with the number of ATP molecules generated per glucose in aerobic respiration (see figure 6.8). How do these numbers compare to the ATP yield from fermentation?
