A researcher prepares 100 mL of aqueous
solution containing 0.1 g of a protein. The
researcher then uses an experimental
apparatus ,where he notes that, at room
temperature (300K) and atmospheric
pressure (101.325 kPa), distilled water
flows naturally into the solution
compartment. However, when he applies
an extra pressure of 1000 Pa he observes
that the flow of distilled water ceases and
the system is in balance.
Calculate the molar mass of this
protein, in kDa (1 Da = 1 g/ mol);
Why does the flow of distilled water
cease with the application of the
pressure of 1000 Pa? Explain in
terms of potential chemicals.

The distribution of Na* ions across a typical biological membrane is 10 mmol/dm3
inside the cell, and 140 mmol/dm³ outside the cell. At equilibrium, the
concentrations across the membrane are equal. What is the Gibbs energy
difference across the membrane at 37°C?
The stated difference in concentration MUST be maintained by coupling to
reactions that have at least your calculated difference of Gibbs energy.
Ans: 6.8 kJ/mol
An important buffer system in the human body involves carbon dioxide (CO2), carbonic acid (H2CO3), and bicarbonate ions (HCO3-) as shown: If a person becomes excited and exhales large amounts of CO2, how will his or her body’s pH be affected?

For example, 1M = 1 mole/L. To determine how many grams of a substance is equal to one mole the molecular mass is needed (we will not explore this in this lab rather this is taught in your Chemistry subjects). The general formula for making a dilution solution is the following: CıV1 = C2V2 where C: = the original concentration of stock solution Vi = the volume of stock solution needed to make working solution C2 = the desired concentration of working solution V: = the desired final volume of working solution For Educational Purposes Only SLSU-TO/NCMatondo 18 What would be the working stock concentration (in molarity) if you diluted 250 ul of a stock concentration of 10 µM in a total volume of 1 mL?

- The normal range of the sodium electrolyte in the body is 134 to 145 mEq/L. The term mEq is dependent on the charge of the ion. Since sodium is a +1 ion, 134 mEq/L is the same as 134 mmol/L. An ion that has a greater positive or negative charge; however, will have 1 mEq for each positive or negative charge of the ion for every 1 mmol. For example, for Ca+2, 2mEq/1mmol. If the standard range of Magnesium in the body is 0.70 to 0.95 mmol/L, convert this value into mEq/L for the Mg2+ ion.

The others have started to drink the seawater to quench their thirst. Since you’re waiting for rescue (and are a top notch AP Biology student), you decide to solve a couple of water potential problems to determine if drinking sea water is a good idea or not. a) The majority of dissolved ions in seawater is NaCl, roughly a 0.5M concentration. The ionization constant of NaCl is 2.0. Calculate the solute potential for seawater if you know that the water is 2°C. b) Your own cells have a 0.15M concentration. Calculate the solute potential for your own cells, knowing that body temperature is 37°C. c) Using your knowledge about water potential, if you drink the seawater, wat will happen when the seawater comes into contact with your body’s cells?
