How the variation of pH affect the permeability of beet root plasma membrane?

Decreasing the pH from alkaline to acidic denatures the proteins within the membrane, making them less functional and efficient. This makes the cell membrane more permeable and allows the red dye, betalain to escape into the external solution via diffusion. The dye goes down a concentration gradient from a higher to a lower concentration.

How does the permeability of the plasma membrane relate to homeostasis?
who the knows
Selective permeability refers to the fact that the plasma membrane keeps all molecules out of the cell?
Selective permeability refers to the fact that the plasma membrane can choose which molecules to let in or out of the cell.
What is the feature of plasma membrane that keep some substances out?
Selective Permeability
What feature of the plasma membrane that keeps some substances out?
Selective Permeability
Is homeostasis the quality of a plasma membrane that allows oxygen and glucose to move in?
Selective Permeability
What property describes the plasma membrane's ability to regulate movement of molecules into and out of the cell?
permeability
What does the difference in the K and Na concentration on either side of the plasma membrane (and permeability of the membrane to those ions) generate?
Resting membrane Potential
Is the cell membrane permeable to glycerol?
No. Permeability of glycerol through plasma membrane= (approx) 1.9 x 10^-9 m/sec Permeability of water through plasma membrane = 2.0 x 10^-6 m/sec
