Escherichia coli, is a type of bacteria that lives in the intestines. It's also found in the gut of some animals. Most of them are harmless, they aid keeping the digestive tract healthy. Though if contaminated food or fouled water is consumed, some strains can cause diarrhea .
Catalase enzymes, hydroperoxidase I (HPI) and HPII, catalyze the dismutation of hydrogen peroxide to water and oxygen but they play crucial roles in protecting cells against the effects of oxidative stress.
Some examples of pathogenic microorganisms which produces catalase include staph, bacillus, aureus,etc
Test Procedure:
- With the aid of a loop or sterile wooden stick, a small amount of bacterial colony should transferred onto the surface of clean, dry glass slide .
- A drop of 3% Hydrogen peroxide should be placed on to the slide and mixed.
- A positive result is indicated by the rapid evolution of oxygen gas (within 5-10 seconds), which is evident by bubbling, while a negative produces no bubbles or only a few scattered bubbles.
- The used slide should be disposed in the bio hazard glass disposal container.
It helps to classify all the different organisms out there in an orderly way.
Answer: If Jasmine received a shot of 'Erythropoietin', it would stimulate the growth the of hemocytoblasts and myeloid stem cells which in turn will also stimulate the growth of lymphoid stem cells.
Explanation: Let me explain some of the terms you used.
'Haematopoiesis' is the formulation of blood cell components.
'Hemocytoblasts' is one of the major components used in the formulation of different types of blood cells.
'Myeloid Stem Cells' is a type of blood cell while 'Lymphoid' stem cells are responsible for the production of immunity against infections and diseases.
Naturally, Erythropoietin is a hormone produced by the kidney. Chemically, it is a protein with an attached sugar (glycoprotein). The main function of the Erythropoietin is that it promotes the formation of the red blood cells by the bone marrow. When injected, it serves as a stimulant for the growth of specific types of blood cells in the bone marrow. In turn, the rise in red blood cells increases the oxygen carrying capacity of the blood.
