Comments P.678 right column bottom paragraph: "There are two types of energy cost during chemotaxis: one for running and tumbling (“the cost of searching for a resource”) and one for moving along a gradient (“the cost of migrating toward that resource”) (primary source). These costs are different for cells of different diameters, as reflected in the relative values in Table 4. It is clear that even slight changes in diameter dramatically alter the energy cost of chemotactic motility (primary source). For example, consider a cell with a flagellum 10 times longer than the cell is wide. Compared to a cell 0.4 μm in diameter, ∼5 times more energy is required to move a cell 1.0 μm wide, ∼20 times more to move a cell 1.6 μm wide, and ∼40 times more to move a cell 2.0 μm wide (Table 4) (from Fig. 2B in primary source)."
