a. Percent of water inside the cell is 100%
b. Percent of water outside the cell is 50%
c) Yes, from outside the cell to inside the cell.
d) Yes, from outside the cell to inside the cell.
e) No, the membrane is impermeable to starch.
f) Yes, from inside the cell to outside the cell.
g) Yes, from inside the cell to outside the cell.
h) No, the membrane is impermeable to Ca+.
i) The solution in the beaker is hypertonic (higher solute concentration) compared to the inside of the cell.
What is osmosis?
Osmosis is the movement of water molecules across a selectively permeable membrane from an area of low to high concentration.
Given the following information
In the cell:
Water: 100%, Glucose: 5%, Starch: 10%, Na+: 10%
, K+: 5%, Ca+: 0%
Outside the cell: Water: 50%, Glucose: 20%, Starch: 0%, Na+: 5%, K+: 15%, Ca+: 10%
a. Percent of water inside the cell is 100%
b. Percent of water outside the cell is 50%
c. Will osmosis occur? If so, in what direction?
Osmosis will occur because there is a concentration difference of water. It will move from the region of higher water concentration (outside the cell) to the region of lower water concentration (inside the cell).
d.Will glucose diffuse? If so, in what direction? Yes, glucose will diffuse. It will move from the region of higher concentration (outside the cell) to the region of lower concentration (inside the cell).
e. Will starch diffuse? If so, in what direction
No, starch will not diffuse as the membrane is impermeable to starch.
f. Will Na+ diffuse? If so, in what direction?
Yes, Na+ will diffuse. It will move from the region of higher concentration (inside the cell) to the region of lower concentration (outside the cell).
g. Will K+ diffuse? If so, in what direction?
Yes, K+ will diffuse. It will move from the region of higher concentration (inside the cell) to the region of lower concentration (outside the cell).
h. Will Ca+ diffuse? If so, in what direction?No, Ca+ will not diffuse as the membrane is impermeable to Ca+.
i.Is the solution in the beaker hypotonic, hypertonic, or isotonic?
The solution in the beaker is hypertonic (higher solute concentration) compared to the inside of the cell.
