The concentration of calcium in a cell is 0.3 .The concentration of calcium in the surrounding fluid is 0.1%.How could the cell obtain more calcium?
Answers
Answer:
•The cell can obtain calcium from outside the cell through osmosis when the
concentration of solute outside the cell is
more the concentration of solute inside the
cell, ie it can travel across the cell membrane through passive transportation.
•But when the concentration of solute is
less outside the cell than the concentration
inside the cell, then it perform active
transportation.
• In this, membrane proteins
are used to transport solutes from outside
to inside against the gradient. It involves
the use of ATP to move the solute inside the cell.
•For example: Na- K pump.
