Question

Review Uuristas A red blood cell is placed into each of the following solutions. Indicate whether crenation, hemolysis, or neither will occur. • Solution A: 2.19 % (m/v) NaCl • Solution B: 4.42 % (m/v) glucose • Solution C: distilled H2O • Solution D: 9.6 % (m/v) glucose • Solution E: 5.0% (m/v) glucose and 0.9% (m/v) NaCl Drag each solution to the appropriate bin.

Answer 1

Red blood cell ich enclosed by a Call membrane, which is selectively permeable. Molecules can move" into or out of the this cell membrane by diffusion of active transport. here, red blood cells will gain or Ide the water by asmosis Osmosis is a process where Wate molecule diffuse from lower solute concentration to higher solute concen- -tration. If a red blood cell CRBC) is placed .. in a typer tonic solution, the solution which has higher solote concentration than cell (RBC) cytosol. So, arater acill move from cell to the solution untill both the scution has same solute concentra rationie. isotonic & RB C ondergo Creation. I If RBC is placed in a lypo tonic solution then the adution all have lower solute concentration than cytosol of RBC. So, water acill move to inside the RBC from the solution until both the solution become isotonic of this leads to homoysin ultimately, If RBC is placed in a isotonic solution or which has name solute concentration as cytosol of RB C. Here, move in of water into RBC i equal to move out of water from & BC & nothing will happen

Exauple of isotonic solution o og 7. (mp) wao 5.0% (m/v) glucose. # Solutiont: 2.19% (w/v) wach which is greater than 0.9% (ms) Noes. So, solution A is hypertonie & RBC will undergo core nation # solution B: 4:42 7. ses glucon which is less than 50% ers) gluense So, solution B is hypotonic & RBC Aull undergo hamolysis solution c: distilled water which is hypotonic with respect to RBC. So, RBC will undergo hemolysis # Solution D: 96% (MW) gheore X5% (on/n) So, saution keypertonie & glucore RBC undergoes crenation # Solution : 5.0%. Forſ) glucore of 0.9% (rn) Nacl solution which is isotonie with RBC. So, neither acill occur solu : AMwen Hemolysin. Core notion AD Neither ке Е B,C
