Structure of hemoglobin and how does oxygen bind to it

1 answer:

3 0

Hemoglobin is a protein that exists in the red blood cells. Hemoglobin contains iron atoms in its chemical structure which are responsible for binding with oxygen or carbon dioxide. In its final structure, Hemoglobin contains 4 sites that can bind to oxygen. Despite that, it's difficult for a hemoglobin molecule to bind with four oxygen atoms at the same time because the structure will be complicated. Hemoglobin combined with oxygen is called oxyhemoglobin, while that combined to carbon dioxide is called carboxy hemoglobin.

postnew [5]

The large population of microbes that contributes to the gut microbiota and have an important role in food processing are called Commensal microorganisms .

The human body is host to trillions of microbes or bacteria. Most of these are useful but may become harmful when out of control.

The microbiota consists of a wide variety of bacteria, viruses, fungi ,and other microorganisms present in a singular environment such as the human digestive tract.

<h3>Gut microbiota : </h3>

The gut microbiota is vast and complex collection of microorganisms that profoundly affects human health gut microbiota are present in the digestive tract of vertebrates including humans.

The function of gut microbiota in body function includes harvesting energy from digested food, protecting against pathogens, regulating immune system and strengthening biochemical barriers of the gut and intestine changes in microbiota composition can affects these functions.

The normal gut microbiota have specific functions like host nutrition metabolism, maintenance of structural integrity of the gut mucosal barrier, helps in immunity, protect against pathogens.

<h3>Commensal microorganisms:</h3>

Commensal microorganisms are those type of microbes that reside on either surface of the body or at mucosa without harming human health . commensal bacteria are 10 times more than the cells present in our body.

Example - Streptococcus oralis and Streptococcus salivarius .

Commensal microorganisms plays an important role against pathogens including respiratory pathogens. It acts on the host's immune system to induce protective response that prevents colonization an invasion by pathogens. On the other hand these bacteria can directly inhibits the growth of respiratory pathogens by producing antimicrobial products .it also competing for nutrients and adhesion sites. Provides the host with essential nutrients.

<h3>What are microbes ?</h3>

Microbes are tiny living things that are found all around us and are too small to be seen by eye. They live in soil, water and in air. The human body is the home of trillions of microbes.
