What is different about the secondary, tertiary, and quaternary structure of each protein?

sweet-ann [11.9K]

Primary structure is the order in which what amino acid bound the other with a peptide bond. This is coded for by the order of codons in a gene

secondary structure is how the chains on amino acids interact with each other to form beta barrels and alpha helixes. This structure is determined by hydrogen bonds between the different amino acids

Tertiary structure is when the secondary structures interact with each other through disulphide bonds, hydrogen bonds hydrophobic/ hydrophilic interactions etc. This is all determined by the placement of certain anino acids within the proteins secondary structure

hope this helped you!!!!

Carbon monoxide (CO) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. A concentratio

velikii [3]

<u>Answer:</u> The amount of CO that is occupied in the room is $1.98\times 10^3L$

<u>Explanation:</u>

We are given:

Concentration of CO = $8.00\times 10^2ppm=800pm$ by volume

This means that $800\mu L\text{ or }800\times 10^{-6}$ of CO is present in 1 L of blood

To calculate the volume of cuboid, we use the equation:

$V=lbh$

where,

V = volume of cuboid

l = length of cuboid = 10.99 m

b = breadth of cuboid = 18.97 m

h = height of cuboid = 11.89 m

$V=10.99\times 18.97\times 11.89=2478.83m^3$

Converting this into liters, by using conversion factor:

$1m^3=1000L$

So, $2478.83m^3=2.479\times 10^6L$

Applying unitary method:

In 1 L of blood, the amount of CO present is $800\times 10^{-6}$

So, in $2.479\times 10^6L$ of blood, the amount of CO present will be = $\frac{800\times 10^{-6}}{1}\times 2.479\times 10^{6}=1983.2L=1.98\times 10^3L$

Hence, the amount of CO that is occupied in the room is $1.98\times 10^3L$
