 Context examples 

Chemotaxis Induction involves initiation of characteristic movement or orientation of an organism or cell along a chemical concentration gradient either toward or away from a chemical stimulus.

(Chemotaxis Induction, NCI Thesaurus)

Osmotic Activity is a passive process in which water diffuses across a cell membrane in response to a concentration gradient.

(Osmotic Activity, NCI Thesaurus)

The characteristic directional movement or orientation of an organism or cell along a chemical concentration gradient either toward or away from the chemical stimulus.

(Chemotactic Process, NCI Thesaurus)

Chemotaxis Inhibition involves interference with, or restraint of, characteristic movement or orientation of an organism or cell along a chemical concentration gradient either toward or away from the chemical stimulus.

(Chemotaxis Inhibition, NCI Thesaurus)

A method to determine microbial susceptibility to antibiotics in which an agar plate, which has a concentration gradient of the drug within the agar, is streaked with the microorganism of interest.

(Gradient Diffusion Method, NCI Thesaurus)

The U-shaped portion of the nephron between the proximal and distal convoluted tubules with descending, ascending, and thick ascending limbs which sets up a concentration gradient in the medulla.

(Henle's Loop, NCI Thesaurus)

(Hearing different frequencies, NIH)

The antibiotic diffuses from the strip producing a concentration gradient of drug on the agar.

(Epsilometry, NCI Thesaurus)

This enzyme allows protons to flow back down their concentration gradient across the membrane, and in the process uses the energy of the gradient to drive ATP synthesis.

(Electron Transport Pathway, NCI Thesaurus/BIOCARTA)

Active Transporter Interaction involves temporary non-covalent binding of a molecule through intermolecular physical forces of attraction with a protein that, after conformational change, moves a bound substrate across a cell membrane with (symport) or against (antiport) a concentration gradient resulting directly from the expenditure of energy.
