The native structure of hemoglobin (hb) comprises of two α and two β subunits, each of which carries a heme group. there appear

to be no previous studies that report the in-vitro folding and assembly of hb from highly unfolded α and β globin in a 'one-pot' reaction. one difficulty that has to be overcome for studies of this kind is the tendency of hb to aggregate during refolding. this work demonstrates that denaturation of hb in 40% acetonitrile at ph 10.0 is reversible." (j am soc mass spectrum 2007, 18, 8-16) how many heme groups are present in three hemoglobin protein molecules?

If each subunit of a hemoglobin protein molecule carries a heme group and a hemoglobin protein molecule is made of four subunits, two α and two β, we can simply multiply four (number of heme groups that can be found in one hemoglobin protein molecule) by three (number of hemoglobin protein molecules considered). 4×3=12

There are twelve heme groups in three hemoglobin protein molecules.

Further Explanation:

Hemoglobin molecules:  

Hemoglobin, additionally spelled hemoglobin, iron-containing protein in the blood of numerous creatures in the red platelets (erythrocytes) of vertebrates, that transports oxygen to the tissues. Every hemoglobin particle is comprised of four heme gatherings encompassing a globin gathering, framing a tetrahedral structure.  

Hemoglobin protein molecules:  

Hemoglobin is the protein that makes dark red. It is made out of four protein chains, two alpha chains and two beta chains, each with a ring-like heme gathering containing an iron particle. Oxygen ties reversibly to these iron iotas and is shipped through blood.  

Which protein is found in hemoglobin:  

The name hemoglobin is gotten from the words heme and globin, mirroring the way that every subunit of hemoglobin is a globular protein with an installed heme gathering. Every heme gathering contains one iron iota, that can tie one oxygen particle through particle initiated dipole powers.  

Ordinary hemoglobin types include:  

• Hemoglobin A (Hb A): makes up about 95%-98% of hemoglobin found in grown-ups; it contains two alpha (α) chains and two beta (β) protein chains.  

• Hemoglobin A2 (Hb A2 ): makes up about 2%-3% of hemoglobin found in grown-ups; it has two alpha (α) and two delta (δ) protein chains.

Which are characteristics of all protists? Select two options.
Andru [333]

Answer:

<h3>The correct answers are :</h3>

<u>(B) They have nuclei </u>

<u>(C) They live in moist environments.</u>

Explanation:

Protists are very diverse group of organism, it contains all the organisms that does not fits into other kingdom. All of the protists are not heterotrophs some of them are autotrophs. They reproduce sexually but some of them reproduce asexually. Example: amoeba: binary fission. Some of the protists are multicellular. Some of them are unicellular too.

Cholesterol transported from the cells to the liver by HDL can then be used to synthesize bile.
Leto [7]

Answer:

True

Explanation:

Cholesterol is a lipid organic molecule which is the modified steroid form. The cholesterol is secreted by the animal cells as it a constituent of the animal cell membrane.

The cholesterol easily dissolves in the blood and is hydrophobic in nature so cholesterol is transported into the blood plasma in the form of lipoprotein complex.

There are four types of lipoproteins formed on the basis of their cholesterol density which are: VLDL, LDL, IDL and HDL.

HDL or high-density lipoprotein transports the cholesterol to the hepatic cells of Liver where the Liver enzymes convert the cholesterol to the bile acid and thus bile juice is excreted with bile.

Thus, True is the correct answer.
