Kidney Cancer KIdney Cancer is when cells in the body grow out of control. These cells can form a tumor or damaged tissue. If cancer cells grow in the kidney‚ it is called kidney cancer. The most common kidney cancer in adults is renal cell carcinoma. It forms in the lining of very small tubes in the kidney. Cancers found in the center of the kidney are known as transitional cell carcinoma. Wilms tumor is a kidney cancer that very young children can get. On average‚ people are diagnosed with kidney

iron in the center. It is the iron that binds the oxygen in a weak interaction that can easily broken. A RBC (red blood cell) is packed with haemoglobin molecules. The cell has no nucleus‚ so more haemoglobin molecules can be included. 2 Function of haemoglobin in Transporting Oxygen: * transport of O2 * transport of some CO2 from body cells to the lungs * conversion of CO2 to HCO3- by the action of the enzyme carbonic anhydrase in the RBC; HCO3- produces H+

sort of problem with its red blood cells (RBCs). If a person’s blood does not have the right amount of red blood cells or hemoglobin‚ anemia can develop. Anemia is defined as a decrease in the circulating red blood cell mass and an equal decrease in the oxygen carrying capacity of the blood (also known as hemoglobin). There are many types of anemia that are grouped by their underlying cause. To determine which type‚ doctors describe color‚ size‚ and shape of red blood cells. Treating it has to be specific

The disorder results in excessive destruction of red blood cells‚ which leads to anemia. Causes‚ incidence‚ and risk factors: Hemoglobin is made of two proteins: Alpha globin and beta globin

homeostasis about 2.5 million of those erythrocytes are destroyed and replace every second. The life cycle of an erythrocyte is 120 days. In the short lifetime the erythrocytes make an astonishing 75000 round trips between the lungs‚ heart and cells of the body. Erythrocytes do not possess a nucleus they are unable to repair or synthesize new cellular components and eventually they wear out. When they wear out most aging erythrocytes are pulled out of circulation by specialized leukocytes called

The use of banned performance-enhancing drugs (PEDS) in sports is commonly referred to as doping. The word doping is probably derived from the Dutch word dop‚ the name of an alcoholic beverage made of grape skins used by Zulu warriors in order to enhance their prowess in battle. The term became current around the turn of the 20th century‚ originally referring to illegal drugging of racehorses. ‘Doping’ however is as old as competitive sport itself. Modern times - In 1904 Olympics

Enzymes All enzymes are globular proteins and round in shape They have the suffix "-ase" Intracellular enzymes are found inside the cell Extracellular enzymes act outside the cell (e.g. digestive enzymes) Enzymes are catalysts → speed up chemical reactions Reduce activation energy required to start a reaction between molecules Substrates (reactants) are converted into products Reaction may not take place in absence of enzymes (each enzyme has a specific catalytic action) Enzymes catalyse
