Do the cells in your body swell up and possibly lyse each time you drink water?
Homework Answers
Humans have flexible cell membranes which allow enlarging or shrinking up. Such a membrane also plays an important part in controlling the substances entering or leaving the cell.Whenever there is a change in concentration of salts and molecules of external fluid the cells will reactsby changing the inner concentration to match with that of outside. So if we drink more water external solution becomes more dilute, or hypotonic,due to which water will move into the cell until there is a balance between external and internal concentration.As a result the cell enlarges, or swells. This change can be minor but if severe it may cause damage and destroy the cell

When you drink cold water, your body must expend metabolic energy in order to maintain normal body temperature (37.0°C) by warming up the water in your stomach. Could drinking ice water, then, substitute for exercise as a way to "burn calories?" Suppose you expend 490. kilocalories during a brisk hour-long walk. How many liters of ice water (0°C) would you have to drink in order to use up 490. kilocalories of metabolic energy? For comparison, the stomach can hold about...

When you drink cold water, your body must expend metabolic energy in order to maintain normal body temperature (37.0°C) by warming up the water in your stomach. Could drinking ice water, then, substitute for exercise as a way to "burn calories?" Suppose you expend 510. kilocalories during a brisk hour-long walk. How many liters of ice water (0°C) would you have to drink in order to use up 510. kilocalories of metabolic energy? For comparison, the stomach can hold about...

If red blood cells are taken from the body and placed in a hypertonic solution, what happens to the cells? The cells remain unchanged due to equal solute concentrations inside and outside the cells. The cells remain unchanged due to equal water concentrations inside and outside the cells. They become white blood cells. The cells swell and burst because water moves into them. The cells shrivel up because water leaves them.

1. (a) The human body contains4.7L of blood. If you drink 1 cup (237 mL) of orange juice, which contains 0.13M concentration of citric acid, what will be the pH of your blood? (You can consider your blood to be initially pure water.) The Kal of citric acid is 7.1 x 10-4 (b) Blood pH must remain between 7.35-7.45 for normal cellular metabolism. A pH < 6.8 or pH > 7.8 is not compatible with life. Comment on this and...

Erythrocytes (red blood cells) swell or shrink rapidly in response to changes in the osmolarity of the blood by the movement of water molecules through plasma membrane channels called aquaporins (AQP). AQP1 is a tetramer that consists of four identical monomers, each of which has a transmembrane pore. A human erythrocyte has approximately 2.0 x 10° AQP1 monomers and a total volume of 9.4 x 10-" mL Water molecules flow through the plasma membrane at a rate of 5.0 x...
