The supply of hydrogen ions will also depend upon their concentration, i.e. the pH of the electrolyte. A concentration gradient in the electrolyte is illustrated. ·If the electrolyte is unstirred, the ...

Scientists designed autonomous nanovesicles capable of following glucose concentration gradients, even through the blood brain barrier in rats. Amid cuts to federal funding, US universities tighten ...

It seems that concentration gradients of morphogens outside a cell ultimately impact the activity of transcription factors (activators and repressors) to regulate transcription within the cell's ...

The idea of concentrations and the gradients within them is important when understanding the movement of particles or molecules across cell membranes. A solution with a low solute concentration ...

Diffusion Substances move from a high to a lower concentration down a concentration gradient Carbon dioxide, oxygen, water, food substances, wastes, eg urea No Osmosis Water moves from a high to a ...
