In order to keep the osmotic pressure in the cell constant, starch and glycogen molecules are a means for a plant or animal cell to store glucose. Cells require sugar or glucose as a source of energy for many different functions.

What is isotonic pressure?
A term applied when two solutions have identical concentrations of of solute molecules and hence the same osmotic pressure, or isotonic pressure.
What is osmotic rate?
the change of osmotic pressure over time
How do net hydrostatic pressure and net osmotic pressure each change along the length of a capillary?
Net osmotic pressure stays about the same and net hydrostatic pressure decreases.
The pressure that is exerted on the inside of cell walls and that is caused by the movement of water into the cell?
Osmotic pressure across the cell wall, here called Turgor Pressure.
The pressure that builds in a plant cell as a result of osmosis is called?
The pressure that builds in a plant cell as a result of osmosis is called turgor pressure.
Why are complex carbohydrates better for storing energy than simple sugar?
Simple sugar molecules will create lot of osmotic pressure in the cell. In case of glycogen, you have thousands of glucose molecules put together. Glycogen molecule is compact and does not produce much osmotic pressure.
What is the relationship between TDS and osmotic pressure?
TDS increases the osmotic pressure. From the formula, Osmotic pressure = CRT. C as the concentration in mol / L; R = gas constant; T = temperature. The higher the concentration of the solids, the higher is its osmotic pressure.
Molecules within the blood are forced out through the walls of capillaries as a result of osmotic pressure?
false- osmotic pressure draws water in capillaries hydrostatic pressure forces water out
What is isotonic pressure?
A term applied when two solutions have identical concentrations of of solute molecules and hence the same osmotic pressure, or isotonic pressure.
When water and useful molecules are drawn back into the blood due to osmotic pressure?
Glomerular Filtration
How does the liver control glycogen?
* Glycogenesis - the conversion of excess glucose into glycogen as a cellular storage mechanism; this prevents excessive osmotic pressure buildup inside the cell * Glycogenolysis - the breakdown of glycogen into glucose, which provides a glucose supply for glucose-dependent tissues. * Gluconeogenesis - de novosynthesis of glucose molecules from simple organic compounds. an example in humans is the conversion of a few amino acids in cellular protein to glucose.
When water and useful molecules are drawn back into the blood due to osmotic pressure it is called?
Glomerular Filtration
What does hypo-osmoregulatory mean?
Below normal maintenance of an optimal, constant osmotic pressure in the body of a living organism.
Which of the colligative properties is not dependent on vapor pressure boiling point elevation vapor pressure reduction osmotic pressure?
Osmotic pressure.
What do plasma proteins that remain in the blood capillaries help?
Maintain the osmotic pressure of the blood
What determines the osmotic pressure of any given solution?
Osmotic pressure of saline (0.91% NaCl w/v) is arround 0.0085 ATM.The osmotic pressure is 7.58 ATM at 25 °C. P=MRT The molarity of 0.9% NaCl is 0.155M. But it has 2 ions per formula so 0.31 mol/L * 0.082 latm/Kmol * 298K= 7.58 ATM
What term refers to diffusion of water molecules through a selectively preamble membrane?
Osmosis is the diffusion of water molecules through a semi-permeable membrane to equalise osmotic pressure.
