Hemoglobin

What is the biological importance of hemoglobin in relation to myoglobin?

[SMIYAZAKI_1B]

Hemoglobin’s purpose is to carry important biological molecules like oxygen and carbon dioxide. Myoglobin’s purpose is to store oxygen within itself. Myoglobin’s stored oxygen are often times used by the muscles when there is a huge need of the oxygen upon physical activities to create energy.

myoglobin transports oxygen to muscle cells. while hemoglobin carries oxygen to the blood and tissues in the body. it also helps transport carbon dioxide and hydrogen ions.

it transfers oxygen via myoglobins

They are both hemeproteins. Their main physiological value is their ability to bind to oxygen.

[Andrew Yoon 3L]

Both hemoglobins and myoglobins are hemeproteins. However, hemoglobins are found in red blood cells and diffuses oxygen throughout the body. This oxygen goes through the blood and tissues of the body. Myoglobins are found in muscle cells, and they store oxygen in the muscle cells.

Just to add on, although both transport oxygen, hemoglobin can bind to more oxygen molecules at a time. I believe hemoglobin can bind to 4 oxygen molecules while myoglobin can only bind to 1 oxygen molecule at a time.

[Samudrala_Vaishnavi 3A]

The biological importance is that it binds to an oxygen ligand, specifically through five bonding points (4 nitrogen atoms binding points that also connect to a central iron atom and one histidine binding site which also is through another nitrogen atom) in this way a red blood cell can deliver oxygen to parts in the body that need it. It also acts as a storage mechanism for the body.

Both myoglobin and hemoglobin are hemeproteins, which their ability is to bind to molecular oxygen. Myoglobin helps with the transportation of oxygen in muscle cells as well.

[Queena Chu 3E]

Hemoglobin is an oxygen transport protein found in red blood cells while myoglobin serves as an intracellular storage site for oxygen.

[rhettfarmer-3H]

Hemoglobin is used in our blood to transfer oxygen and myoglobin is used in our muscles to transfer o2 too. Hence, both are made of the same structure the heme structure with the same protein and 02 Hence, one is just more complex than the other. For example, the hemoglobin is 4 myoglobin which comments on their ability to transfer o2 and their ability to have the same function.

[Nick Saeedi 1I]

Hemoglobin carries oxygen through the blood while Myoglobin carries oxygen through the muscles.

[kristinalaudis3e]

Hemoglobins transports oxygen through the blood and myoglobins store oxygen in the muscles

[Neha Jonnalagadda 2D]

I think that hemoglobin carries the oxygen around the bloodstream while myoglobin will store oxygen in the muscle tissue.
