Oxygen carried in a hemoglobin molecule is bound to a/an

[ad_1]

Oxygen carried in a hemoglobin molecule is bound to an iron atom. 
The red blood cells contain a pigment called hemoglobin, each molecule of which binds four oxygen molecules.
This protein carries oxygen to the cells and carbon dioxide to the lungs. 
It is the iron atom that binds oxygen as the blood travels between the lungs and the tissues.

Many different types of mutations can occur within the body. Sickle cell anemia is a disease that occurs when a mutation in a base pair of the hemoglobin beta gene causes a single replacement of the amino acid glutamic acid by the amino acid valine. As a result of this mutation, the individual’s blood cells take on a sickle shape under certain conditions and form clusters that can block blood vessels and cause organ damage. Which type of mutation causes sickle cell anemia? A)silent B)missense C)insertion D)frameshift

[ad_1]

The right option is; B)missense

Missense mutation is the type of mutation that causes sickle cell anemia

A missense mutation is a type of nonsynonymous substitution in which the change of a single nucleotide (base pair) influences the genetic code and results in a codon that code for a different amino acid. This type of mutation can affect the function of the protein, and it is responsible for human diseases such as, sickle-cell anemia and Epidermolysis bullosa.

Carbon dioxide enters the blood at the _____________________ capillaries. here, some of the carbon dioxide binds to the _____________ region of hemoglobin.

[ad_1]

Answered by answersmine AT 22/10/2019 – 05:00 AM

Carbon dioxide enters the blood at the systemic capillaries. Here, some of the carbon dioxide binds to the globin region of hemoglobin. The systemic capillaries function to carry oxygenated blood for the tissues of the body. As it enters these capillaries, blood would lose oxygen and in return gain CO2 molecules due to the difference in pressure of the tissues and the blood.

In the lungs, oxygen diffuses into the blood and is loaded onto hemoglobin for transport. in the tissues, oxygen is unloaded from hemoglobin and diffuses from the blood into nearby cells. what drives the diffusion of oxygen?

Answer:

The integumentary system covers the surface of the body is true about the integumentry system.

Explanation:

The integumentary system includes the skin, nails, glands, hairs, and nerves. Its main role is to act as a barrier to protect the body from the outside environment. It also retains body fluids, regulates body temperature, eliminates waste products, and protects against disease.

The integumentary system is the largest organ in the body that covers the surface of the body.

Thus, The integumentary system covers the surface of the body is the true statement about the integumentry system.

How does the structure of hemoglobin allow it to combine with oxygen?

[ad_1]

Answer: The correct answer is- D. The shape and folded structure of a protein molecule are important in determining its function.

Proteins are the most diverse group of biologically essential organic molecules that are considered to be significant for life. The basic monomeric unit of protein is amino acid whose sequence affects the function of the protein.

Biologically active form of proteins is their three dimensional structure ( native and active form) that is produced by the folding of protein molecule after it gets synthesized.

Therefore, shape and folded structure of a protein molecule are important in determining its function.

Human red blood cells that lack sufficient hemoglobin would have a low amount of what substance?

[ad_1]

Answer:

The correct answer of Q1 is D. Aids in gas exchange.

The function of gas exchange is performed between lung’s alveoli and capillaries having blood located in the alveolar wall. So skin does not play any role in gas exchange. Therefore the correct answer is D. Aids in gas exchange.

The correct of Q2 is C. kidney

Kidney is the organ that helps in the filtration of blood. It clears the blood from impurities like urea, salt, steroids, and excess water. It does not play any role in digestion. So the correct answer is C. kidney.

The correct answer of Q3 is C. stomach

The stomach contains hydrochloric acid not hydroelectric acid and due to this hydrochloric acid the pH of the stomach is very low between 2-3.5. This pH is beneficial to kill pathogen comes with food. So the right answer is C. stomach.

Where is hemoglobin normally found?

[ad_1]

Answer:

1: D

2: D

3: D

4: D

5: D

Explanation:

1. In some areas of the world, like California and Japan, earthquakes are a common occurrence. How can this best be explained?

  • The surface of the Earth is formed by tectonic plates. These plates sometimes move and the friction between the edges generate the earthquakes.

2. In the diagram of the ocean basin, where is the oldest oceanic crust found?

  • The surface of the Earth is formed from the liquid magma that comes out from the center, through the volcanoes. So, the surface furthest from the volcano is the oldest.

3. When an experiment is repeated and the new results are different from the original results, what could you assume to be true?

  • To get a conclusion, from an experiment, you have to repete it many times and see what is the result that repeted. You can not draw conclutions from one or two results.

4. Which piece of lab equipment has specific markings for highly accurate measurements of liquid volumes?

  • The graduates cylinder, made from glass or plastis, it’s transparent and lets you see precisely where the liquids are.

5. Which question can be answered by an experiment?

  • Cancer is a multi-causal disease. You can’t, through an experiment, say that its generated by replacing sugar.
  • You can guess about what kill them all, but not by an experiment.
  • Again, you can guess or do a reserch about it but you can’t do an experiment.
  • Hunta Virus is a disease, so you could took a group of people and expose them to this disease and see if all of them got it.
