Crenation is the contraction of a cell after exposure to a hypertonic solution, due to the loss of water through osmosis.
Hemolysis is the breakdown of red blood cells.
2% NaCl is hypertonic to red blood cells causing them to shrink and crenate due to water moving out of the cells by osmosis. Hemolysis is likely to occur in hypotonic solutions where red blood cells swell and burst.
If you expose red blood cells to a high concentration of NaCl (salt), water will move out of the cells through osmosis, causing them to shrink and potentially undergo hemolysis (bursting). This process is known as crenation.
Hemolysis can falsely elevate sodium values due to release of intracellular sodium from red blood cells during the process of hemolysis. This can lead to inaccurately high sodium measurements in the blood sample.

H2O is a scientific version for Water, it is on the periodic table :) x
Hemolysis
None
False. Crenation, plasmolysis, and hemolysis are all related to osmotic processes in cells, but turgor pressure is not directly equivalent to hemolysis. Turgor pressure is the pressure exerted by the fluid inside plant cells against the cell wall, while hemolysis refers to the bursting of red blood cells.
A 2 percent solution of sodium chloride is considered isotonic to red blood cells, meaning it will not cause crenation (shriveling) or hemolysis (bursting). Isotonic solutions have the same osmotic pressure as red blood cells, allowing for equilibrium and maintaining cell integrity.
In a hypotonic solution, red blood cells swell and undergo hemolysis, while in a hypertonic solution, they lose water and undergo crenation.
2% NaCl is hypertonic to red blood cells causing them to shrink and crenate due to water moving out of the cells by osmosis. Hemolysis is likely to occur in hypotonic solutions where red blood cells swell and burst.
Red blood cells would exhibit crenation in a 5.0 percent solution of glucose. This is because the solution has a higher solute concentration than the cytoplasm of red blood cells, leading to water leaving the cells causing them to shrink and exhibit crenation.
This should be compared to something before determination can be done. For ex. if relative to blood, 2.8 % of Nacl will cause crenation since it's more hepertonic than blood. Liquid/solute in the blood will then difuse to go out (fr its low concentration) of the RBC cell to a higher concentration wich is Nacl.
Alpha hemolysis is partial hemolysis resulting in a greenish discoloration of the agar, beta hemolysis is complete hemolysis resulting in a clear zone around the colony, and gamma hemolysis is no hemolysis observed.
The three types of hemolysis are alpha hemolysis (incomplete hemolysis, causing a greenish discoloration around bacterial colonies), beta hemolysis (complete hemolysis, causing a clear zone around bacterial colonies), and gamma hemolysis (no hemolysis, with no change in the appearance of blood agar).
Crenation occurs in a hypertonic solution, where the concentration of solutes outside the cell is higher than inside, causing water to leave the cell, leading to shrinkage and deformation of the cell.
The hemolysis is called green hemolysis because of the color change in the agar.
