1. State the principle of the test (the general laws or facts of nature underlying the working of a device or test) Hemoglobin which is also known as HbG or Hb is composed of 2 alpha and 2 beta chains. They both transport a heme molecule. HbG is the primary constituent of red blood cell cytoplasm and transports oxygen from the lungs to the tissues and then returns carbon dioxide to the lungs. HbG can be used to diagnose or monitor a number of conditions. Anemia is one of those conditions.

Pipe cleaners=subunits Green marsh mellow=iron molecule Yellow marsh mellow=oxygen molecule Orange cards= heme groups (wolfe‚ 2000) Oxygenated/deoxygenated oxygenated • 02 bound • Bright red • Subunit is in relaxed form • Higher affinity for 02 • Affinity for oxygen is cooperative‚ which means that the affinity for 02 increases with each bound molecule

Plant Hemoglobin Hemoglobin is a protein-iron compound found within the red blood cells of most vertebrates and is responsible for the cell’s red pigment. These red blood cells carries oxygen from the lungs to the rest of the tissue cells throughout the rest of the body. Just as hemoglobin transports oxygen in humans‚ they have also been found transporting oxygen within plants. In plants‚ there are two types of hemoglobin that can be found; symbiotic and non symbiotic. Oxygen is used

HEMOGLOBIN AND MYOGLOBIN I. OXYGEN CARRIERS A. Why do we need oxygen carriers? i. Cannot carry enough in blood to meet metabolic demand ii. Oxygen is very reactive – oxidizes iii. Oxygen cannot diffuse very easily (we have thick skin) B. Properties of a good oxygen carrier i. Binds oxygen at a high [O2] ii. Doesn’t oxidize cellular components iii. Gives up oxygen on demand C. Hemoglobin and Myoglobin i. Cooperativity 1. Hemoglobin needs to have high affinity to bind O2 in the lungs‚ but low affinity

Definition of Hemoglobin • Description of Hemoglobin • Questions To Ask Your Doctor About Hemoglobin Definition of Hemoglobin Hemoglobin is the iron-carrying protein found in red blood cells that binds to oxygen. Description of Hemoglobin Hemoglobin is a crystallizable‚ conjugated protein consisting of an iron-containing pigment (called heme or hematin) and a simple protein‚ globin. In the lungs‚ it combines readily with oxygen to form a loose‚ unstable compound called oxyhemoglobin

blood is almost transparent because of the lack of red blood cells‚ and they are the only vertebrate that does not have circulating hemoglobin. Those organisms are referred to as Ice fish‚ and they are one of the unique organism that live in Southern Ocean around Antarctica and Southern South America‚ where water temperatures remain relatively stable. Hemoglobin is a protein within mammalian red blood cells that transports oxygen for delivery to tissues throughout the body. Having red blood cells

Thalassemia is genetic disorders that involve the decreased and defective production of hemoglobin‚ a molecule found inside all red blood cells (RBCs) that transports oxygen throughout the body (Miller‚ Thalassemias‚ 2008). As (Hashemi‚ 2011) says "Thalassemia is blood disorders ". As (Clinaero‚ n.d.) says" There are mild and severe forms of
