Given the following initial conditions, in which system will diffusion be from the left to right at the greatest rate? (note that glucose has a greater molecular mass than sodium) a. 0.4M Glucose on the left; .02M Glucose on the right b. 0.2M Glucose on the left: 0.4M Glucose on the right c. 0.2M Nat on the left: 0.4M Nat on the right d. 0.4M Na+ on the left: 0.2M Na+ on the right 3. Given the tonicity within a human cell is 300 mosmoles, which of the following will cause a cell to crenate? a. 200 mOsmole solution of Na+ (a non-penetrating solute) b. 400 mOsmole solution of Na+ (a non-penetrating solute) c. Distiled water d. All of the above will cause crenation 4. Which solution would cause a red blood cell to lyse (burst)? a. 0.3M glucose b. 0.15M NaCl c. Normal Saline d. 0.05M NaCI e. All of the above would cause crenation 5. Distilled water is cons idered to be? a. Hypotonic b. Isotonic c. Hypertonic d. Isoosmotic 6. If multiple solutes are diffusing across a semipermeable membrane, such as glucose and urea they will have what affect on each other? They will make each diffuse faster They will make each diffuse slower They will diffuse independently a. b. c.Explanation / Answer
Answer-
1-(d) 0.6M Na+on the left and0.2M Na+ on the right side.due to concentration gradient.
2-(b) 0.2M glucose on left and 0.4M Glucose on right.
3-(c)Distill water and some time all the solution so sometimes answer is (d) and it is because of factors affect.
4-(e)All of the given option
5- (a) Distill water is hypotonic solution.
6-(a) they will make each other diffusion Faster.
Hope u will understand all the answers.
