| Method |
"Rates of motility were determined by mixing extracted organisms with MgATP, placing a sample of the mixture in a hemacytometer chamber, and measuring the time (with a digital stopwatch) taken for individual cells to swim straight across a 200-µm grid." |
| Comments |
"At least 10 intact or extracted cells were scored, as described in Results, for each [MgATP]. The five fastest swimming rates were then selected and averaged to yield the rates shown, the assumption being that maximum rates are least prone to error due to diagonal paths and/or mechanical obstacles." "Table
