Definition of Concentration gradients
Check what you remember
Read the wording for your board, then hide it and explain Concentration gradients in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Gradients that specialised exchange surfaces, with transport systems, maintain steep so that diffusion continues at a useful rate.
