WebAug 26, 2024 · Well, there’s always a reason for bias. Bacteria can bias their walks based on the concentration gradient of a particular chemical. So even though each step is in a random direction, the length of the step is longer if the bacterium is moving towards a higher concentration than it is if the bacterium is moving towards a lower concentration.

WebThe concentration of sodium in the extracellular solution is about 10 times higher than the intracellular solution, so there is a concentration gradient driving sodium into the cell. Additionally, at rest, the inside of the neuron is more negative than the outside, so there is also an electrical gradient driving sodium into the cell.

WebMar 24, 2024 · Concentration gradient is the difference in the concentration of a particle in one region compared to the other, eg., when the concentration of particles is higher in one area than another.
