what is the function of hemoglobin and where is it found?
153072
Hemoglobin is contained in red blood cells, which efficiently carries oxygen from the lungs to the tissues of the body. Hemoglobin also helps in the transportation of carbon dioxide and hydrogen ions back to the lungs.

Hemoglobin is a two-way respiratory carrier, transporting oxygen from the lungs to the tissues and facilitating the return transport of carbon dioxide. In the arterial circulation, hemoglobin has a high affinity for oxygen and a low affinity for carbon dioxide, organic phosphates, and hydrogen and chloride ions.

Hemoglobinuria is a condition in which the oxygen transport protein hemoglobin is found in abnormally high concentrations in the urine.

Hemoglobin in blood carries oxygen from the lungs or gills to the rest of the body (i.e. the tissues). There it releases the oxygen to permit aerobic respiration to provide energy to power the functions of the organism in the process called metabolism.

Functions of blood. Transports gases, nutrients, waste, cells and hormones throughout the body. Transports O2, CO2, nutrients, hormones, heat and wastes. Regulates pH, temperature, water content of cells.

Hemoglobin. (a) A molecule of hemoglobin contains four globin proteins, each of which is bound to one molecule of the iron-containing pigment heme. (b) A single erythrocyte can contain 300 million hemoglobin molecules, and thus more than 1 billion oxygen molecules.

Red blood cells. Red blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs into the RBCs, where it binds to hemoglobin. One molecule of hemoglobin can bind four molecules of oxygen (O2).

Each hemoglobin molecule is made up of four heme groups surrounding a globin group, forming a tetrahedral structure.

Hemoglobin (American English) or haemoglobin (British English) (Greek αἷμα (haîma, “blood”) + -in) + -o- + globulin (from Latin globus (“ball, sphere”) + -in) (/ˈhiːməˌɡloʊbɪn, ˈhɛ-, -moʊ-/), abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells (erythrocytes) of almost ...

Hemoglobin: The protein inside red blood cells (a) that carries oxygen to cells and carbon dioxide to the lungs is hemoglobin (b). ... It is easier to bind a second and third oxygen molecule to Hb than the first molecule. This is because the hemoglobin molecule changes its shape, or conformation, as oxygen binds.

Hemoglobin, also spelled haemoglobin, iron-containing protein in the blood of many animals—in the red blood cells (erythrocytes) of vertebrates—that transports oxygen to the tissues. Hemoglobin forms an unstable reversible bond with oxygen.

Red blood cells at work Hemoglobin is the protein inside red blood cells. It carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale. Red blood cells are made in the bone marrow.

Iron Metabolism and Its Disorders Myoglobin is an oxygen-binding protein located primarily in muscles. It contains one heme group per molecule and has a structure similar to that of hemoglobin monomers.

It is distantly related to hemoglobin which is the iron- and oxygen-binding protein in blood, specifically in the red blood cells. In humans, myoglobin is only found in the bloodstream after muscle injury. It is an abnormal finding, and can be diagnostically relevant when found in blood.

Red blood cells (RBCs), also known as erythrocytes, have two main functions: To pick up oxygen from the lungs and deliver it to tissues elsewhere. To pick up carbon dioxide from other tissues and unload it in the lungs.
1008261
Hemoglobin is found in red blood cells binding to four oxygen molecules in the lungs and transports them to the tissues. Hemoglobin is not only an oxygen binding protein, it plays a key role in the respiratory pathway which includes binding to carbon dioxide once oxygen is released.

Hemoglobin is the protein that makes blood red. ... Oxygen binds reversibly to these iron atoms and is transported through blood. Each of the protein chains is similar in structure to myoglobin, the protein used to store oxygen in muscles and other tissues.
