How electrochemical gradients and proton gradients are formed and function in cells

1 answer:

8 0

To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.

If the concentration of salt in the fluid surrounding cells decreases and the concentration of other solutes remains constant?

svetoff [14.1K]

Answer:

The cell will swell.

Explanation:

The cells react distinctly when placed in different solutions like hypertonic, isotonic and hypotonic solutions. In the mentioned question, that is, in the fluid surrounding the cells, the concentration of salt reduces, which makes the solution hypotonic. Hypotonic solution exhibit high water potential and low solute concentration.

This makes the water move from the hypotonic solution to the inside of the cell as the osmotic movement occurs from high solvent concentration to low solvent concentration, thus, swelling of the cell takes place.
