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.

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.

Nitrogen is important
uranmaximum [27]

Plants and animals could not live without nitrogen. It is an important part of many cells and processes such as amino acids, proteins, and even our DNA. It is also needed to make chlorophyll in plants, which plants use in photosynthesis to make their food and energy.

Nitrogen is an important component of many essential structural, genetic and metabolic compounds in plant cells. It is also an elementary constituent of numerous important organic compounds including amino acids, proteins, nucleic acids, enzymes, and the chlorophyll molecule.

Of all the essential nutrients, nitrogen is the one that is most often limiting for crop growth. Nitrogen is the nutrient which normally produces the greatest yield response in crop plants, promoting rapid vegetative growth and giving the plant a healthy green color.

Which of the following best describe gas particles?
timama [110]

Answer:

a, b, d (see below)

Explanation:

So, looking at the 3 states of matter:

Solid - holds a shape and is made up of particles that vibrate in place (because particles are always moving no matter what)

Liquid - holds shape of its container and has particles with some space in between them that allow them to flow

Gas - holds shape of its container and has particles with huge gaps of space between them that are always, constantly moving and zooming around

Refer to the image below for a better visual understanding.

So, now, looking at the answer choices:

a) moving randomly

Yes. They are—they're speeding around super fast all the time.

Every time heat is added to something, the particles start loosening up and moving.<em> A lot.</em>

So when you add heat to a solid, it starts loosening up and moving around until it becomes flowy enough to be a liquid. Then, if more heat is added, the particles moving faster and loosen up even more until they're a gas.

Imagine doing that one more time, and you'll have plasma. As you may have guessed it, plasma moves <em>super fast</em>

<em />

b) collide into each other

Yes. Because they're moving so fast and uncontrollably all the time, they're bound to have rammed into one another a few or more times.

Imagine bumper cars at a carnival, except the speed of each car is sooo fast that you could be on a highway. You're probably going to hit someone, which is why bumper cars are not that fast in reality. For safety reasons.

c) move slow

No. Since we know that they're always zooming around (refer to my bumper car example above, in bold), they obviously can't be slow.

d) high kinetic energy

Yes. Anything moving (a.k.a. in motion) has kinetic energy. If gases zoom super fast 24/7, they will have high kinetic energy.

Having high kinetic energy means that the something is moving really fast or a lot. In this case, gases are both.

e) moving orderly

No. They're moving everywhere and really fast, so they have no control over how they move because of how fast they are.

(refer to my bumper car example in answer b, in bold)
