How is hemoglobin's affinity for oxygen affected by the presence or absence of oxygen?

Chemistry

qwelly [4]2 years ago

Answer:

Explanation:

Haemoglobin is a red protein found in red blood cells of vertebrates responsible for transporting oxygen in the blood. Each haemoglobin has capacity to carry four oxygen molecules. When oxygen is available or present, the molecules of oxygen bind to the iron of the heme prothestic group and it's tend to release oxygen when oxygen level is low in the environment. Haemoglobin carries oxygen in lungs and releases it to tissues.

Answer:

Hemoglobin is the pigment present in the red blood cells that helps in the transport of oxygen in the body. A single hemoglobin molecule can binds maximally with four oxygen molecule.

The affinity of the hemoglobin with oxygen depends on the different factors like temperature, presence of the oxygen and the partial pressure. The oxygen affinity for hemoglobin increase with the increase in the oxygen concentration as they shows positive cooperativity. The decline in the oxygen concentration results in decrease in the affinity of hemoglobin with oxygen.

Pls help! Polonium has a large, unstable nucleus. Through which process is it most likely to become stable?
Stella [2.4K]

The process through which Polonium is most likely to become stable is: B. alpha decay.

An unstable element refers to a chemical element that lose particles because its nucleus contain an excess of internal energy (neutron or proton).

This ultimately implies that, an unstable element is radioactive in nature.

In Science, some examples of an unstable element are:

  • Tritium.
  • Bismuth-209 .
  • Xenon.
  • Polonium.

Polonium is a chemical element with a large, unstable nucleus.

Basically, the most stable isotope of Polonium is Polonium-209, which typically undergoes an alpha decay to form lead-205 and the emission of an alpha particle.

⇒  ^{209}_{84}Po ----> ^{205}_{82}Pb \;+\; ^{4}_{2}\alpha

In conclusion, we can deduce from the above chemical equation that Polonium is most likely to become stable through an alpha decay.

What mass of mgo is produced from 2.00 moles of mg ? Mg +02 mgo
Vanyuwa [196]
Chemical Reactions and Moles of Reactants and Products
That is, it requires 2 moles of magnesium and 1 mole of oxygen to produce 2 moles of magnesium oxide. If only 1 mole of magnesium was present, it would require 1 ÷ 2 = ½ mole of oxygen gas to produce 2 ÷ 2 = 1 mole magnesium oxide.

Consider a mixture of oil and water. What terms would you use to describe this mixture? Check all that apply. Heterogeneous homo
GenaCL600 [577]

A mixture of oil and water is:

Heterogeneous

immiscible

<h3>What type of mixture of oil and water is?</h3>

The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water. The mixture can be called as Emulsion. It is an immiscible liquid and the mixture is heterogeneous as oil floats on top of water surface but do not mix with it.

Thus, correct options are Heterogeneous and immiscible.
