What is a prophyrin?

It is an organic compound ( a group ) of which the most commonly known is heme, the pigment that gives blood its red color. Word (prophyrin) comes from Greek word for purple, relates to their deep color. Heme is…

What does hemogoblin do?

a red protein responsible for transporting oxygen in the blood of vertebrates. Its molecule comprises four subunits, each containing an iron atom bound to a heme group.(From THE Macintosh dictionary). a red protein responsible for transporting oxygen in the blood…

What is a cytochrome?

A cytochrome functions like an electron transfer agent in several metabolic pathways. They are any of several compounds that are heme bonded to a protein.

How is oxyhemoglobin formed?

Oxyhemoglobin is formed during physiological respiration. This is when oxygen binds to the heme component of the protein hemoglobin in red blood cells.

Why does body need iron?

The main use of iron in the body is to make heme, the protein building block of hemoglobin. Hemoglobin is the oxygen transporter molecule in red blood cells. There are also other uses but together they take far less than…

Is cobalt present in hemoglobin?

No. In most vertebrates, the hemoglobin (or heamoglobin if you prefer) molecule is an assembly of four globular protein subunits. Each subunit is composed of a protein chain tightly associated with a non-protein heme group. Proteins are amino acid structures…

Blood cells use a protein called?

Red Blood Cells use the protein hemoglobin to transport oxygen throughout the body and carbon dioxide back to the lungs so that it can remove the waste from our bodies through the process of breathing. Hemoglobin also aids in the…

What are the products of hemoglobin breakdown?

Hemoglobin molecules liberated from red blood cells are broken down into subunits of heme, an iron containing portion, and globin, a protein. The heme further decomposes into iron and a greenish pigment called biliverdin. Biliverdin eventually is converted to an…

What is the function of iron?

Hemoglobin, which is found in the blood, is made of four proteins and inside each protein is a heme or iron. Oxygen binds to the iron and is carried to various parts of the body.

What does myoglobin store?

Myoglobin is an oxygen carrying protein in muscles and it stores oxygen and hence it acts as oxygen reservoir.In muscles Oxygen reacts with the heme group and forms oxymyoglobin

What protein needs iron?

Hemeproteins as a group are so named because they contain the heme prosthetic group in which iron is coordinately bound within a porphyrin ring. The iron is the reactive center of the protein and is needed for whatever redox reactions…
