CRITICAL THINKING QUESTIONS 1. A pre-weighed dialysis bag which contained a solution of 10% glucose was placed in a beaker containing a solution of 20% glucose. After one hour, the bag was weighed again a. Calculate the % mass change of this dialysis bag from the following information: • Mass of bag before experiment: 15.39 • Mass of bag after experiment: 12.79 b. Determine the tonicity of the beaker when it is compared to the dialysis bag: 2. facell had...

2. What would happen to each of the following if reduced the supply of glucose to cells by 50%? You may assume that the cell will NOT switch to an alternative energy source. Briefly explain why for each. A. The level of glycolysis activity. B. The level of Krebs Cycle activity. C. The level of activity in the electron transport chain in the mitochondria. D. The size of the proton gradient across the inner mitochondrial membrane. E. The rate of...

. For each of the 3 situations below, use an arrow to indicate the net movement of water into or out of the cell through the semipermeable plasma membrane (i.e. osmosis). (Assume that the sugar molecules cannot pass through the plasma membrane in each case.) 1% sugar (inside a circule) 3% sugar (inside a circule) 1% sugar (inside a circule) 5% sugar 1% sugar 1% sugar 3. In each of the drawings above, indicate if the inside of the cell...

Osmotic Pressure: You are trying to make artificial blood cells. You have managed to get pure lipids to form spherical bags (cells) of radius 10 μm, filled with hemoglobin. The first time you did this, you transferred the cells into pure water and they promptly burst, spilling the contents. Eventually you found that transferring them into a 1 mM salt solution prevents bursting, leaving the cell spherical and full of hemoglobin and water. Explain the reason why the cells burst...

Question 9 Diffusion is an important process at the micro and nano scale and different devices may be designed to minimize it, compensate for it, or take advantage of it. (a) Explain what is meant by the term diffusion and describe how it occurs, illustrating your answer with references to each of the following: (i) a hole in a semiconductor such as silicon (ii) a protein molecule within a living cell. (6 marks) Explain why diffusion could be a particular...

Approximation At some point, scientists are confronted with the recognition that some math problems do not have exact answers. This is very different than the math we learn in high school and college, which typically represents math as a construction that only has exact answers (2 + 2 = 4 and not any other number) What is the expected time of diffusion of biologically important molecules at different scales? There is no exact answer to a question like how long...

can you please help with # 4-6
3. You make a solution that contains 1000 molecules of water. 90 molecules of glucose, and 120 molecules of sucrose. What is the solute concentration of this solution? (2 points) 17.35/ 4. You now add a cell into the solution from question 3. This cell has a 20% solute concentration. a. Is the outside of the cell hypertonic, hypotonic, or isotonic when compared to the inside of the cell? How do you know?...
