Increase Weight Loss 1. High in Antioxidants Antioxidants are compounds that help neutralize harmful free radicalspreventing oxidative stress and damage to your cells. Some studies have found that antioxidants could protect against many types of chronic disease, such as heart disease, cancer and diabetes. In vitro studies have found that these potent pigments may help protect against the development of certain types of cancer and disease.

Function Secondary functions When red blood cells undergo shear stress in constricted vessels, they release ATPwhich causes the vessel walls to relax and dilate so as to promote normal blood flow. Red blood cells can also synthesize nitric oxide enzymatically, using L-arginine as substrate, as do endothelial cells.

Red blood cells can also produce hydrogen sulfidea signalling gas that acts to relax vessel walls. It is believed that the cardioprotective effects of garlic are due to red blood cells converting its sulfur compounds into hydrogen sulfide. As red blood cells contain no nucleus, protein biosynthesis is currently assumed to be absent in these cells.

Because of the lack of nuclei and organelles, mature red blood cells do not contain DNA and cannot synthesize any RNAand consequently cannot divide and have limited repair capabilities.

When matured, in a healthy individual these cells live in blood circulation for about to days and 80 to 90 days in a full term infant.

In many chronic diseases, the lifespan of the red blood cells is reduced. Creation Erythropoiesis is the process by which new red blood cells are produced; it lasts about 7 days. Through this process red blood cells are continuously produced in the red bone marrow of large bones. In the embryothe liver is the main site of red blood cell production.

The production can be stimulated by the hormone erythropoietin EPOsynthesised by the kidney. Functional lifetime The functional lifetime of a red blood cell is about — days, during which time the red blood cells are continually moved by the blood flow push in arteriespull in veins and a combination of the two as they squeeze through microvessels such as capillaries.

They are also recycled in the bone marrow. This process is termed eryptosisred blood cell programmed cell death. Eryptosis is increased in a wide variety of diseases including sepsishaemolytic uremic syndromemalariasickle cell anemiabeta- thalassemiaglucosephosphate dehydrogenase deficiencyphosphate depletion, iron deficiency and Wilson's disease.

Eryptosis can be elicited by osmotic shock, oxidative stress, energy depletion as well as a wide variety of endogenous mediators and xenobiotics.

Inhibitors of eryptosis include erythropoietinnitric oxidecatecholamines and high concentrations of urea. Much of the resulting breakdown products are recirculated in the body.

The biliverdin is reduced to bilirubinwhich is released into the plasma and recirculated to the liver bound to albumin. The iron is released into the plasma to be recirculated by a carrier protein called transferrin.

Almost all red blood cells are removed in this manner from the circulation before they are old enough to hemolyze. Hemolyzed hemoglobin is bound to a protein in plasma called haptoglobinwhich is not excreted by the kidney.

Blood diseases involving the red blood cells include: Anemias or anaemias are diseases characterized by low oxygen transport capacity of the blood, because of low red cell count or some abnormality of the red blood cells or the hemoglobin. Iron deficiency anemia is the most common anemia; it occurs when the dietary intake or absorption of iron is insufficient, and hemoglobin, which contains iron, cannot be formed Sickle-cell disease is a genetic disease that results in abnormal hemoglobin molecules.

When these release their oxygen load in the tissues, they become insoluble, leading to mis-shaped red blood cells. These sickle shaped red cells are less deformable and viscoelastic meaning that they have become rigid and can cause blood vessel blockage, pain, strokes, and other tissue damage.

Thalassemia is a genetic disease that results in the production of an abnormal ratio of hemoglobin subunits. Hereditary spherocytosis syndromes are a group of inherited disorders characterized by defects in the red blood cell's cell membranecausing the cells to be small, sphere-shaped, and fragile instead of donut-shaped and flexible.

These abnormal red blood cells are destroyed by the spleen.

Several other hereditary disorders of the red blood cell membrane are known. Vitamin B12 is needed for the production of hemoglobin. Aplastic anemia is caused by the inability of the bone marrow to produce blood cells. Pure red cell aplasia is caused by the inability of the bone marrow to produce only red blood cells.

Effect of osmotic pressure on blood cells Micrographs of the effects of osmotic pressure Hemolysis is the general term for excessive breakdown of red blood cells.

It can have several causes and can result in hemolytic anemia. The malaria parasite spends part of its life-cycle in red blood cells, feeds on their hemoglobin and then breaks them apart, causing fever.

Both sickle-cell disease and thalassemia are more common in malaria areas, because these mutations convey some protection against the parasite.The nutrient betaine in beets is known for protecting proteins, enzymes and cells from environmental stress.

This in turn helps to reduce inflammation, improve vascular risk factors, protect internal organs and enhance internal performance. eukaryote - type of cell that has a nucleus nucleus - control center of the cell, contains the cell's genetic information cell membrane - the outer boundary of a cell cytoplasm - the fluid within a cell where organelles float 6.

Keeping in mind that the mouth is the first site of chemical. When the beet was heated to 70°c or cooled to -5°c it was subjected to much more stress that at a normal room temperature, which the beet is grown and stored at. The various temperatures make the beet release its pigments. Effect of Stress on Beet Cells Essay.

The Effect of Temperature on Beet Cell Membranes Introduction In this lab, we are going to learn how the stress of temperature affects fresh beets. We have come to learn that cell membranes organize the chemical activities of cells.

All cells are made of plasma membranes, often called fluid mosaics. No.

there is a possibility that these conclusions also work for many cell types derived from various organisms. Though cell structure is different from cell type to cell type depending on the specific functions for that type of cells, all cells are vulnerable to stress. 1) Are your conclusion about membrane structure and stress valid only for beet cells?

Why or why not? 2) What characteristics of beets make them useful as experimental models for studying cellular membranes?
