Since there’s nothing here other than what you’ve asked i’ll guess, an experiment that is more likely to be reliable will not use the first values it gets, will be done multiple times and the values will be close in number

Describe the substrate specificity of chymotrypsin and the structural feature that determines this specificity.
serg [7]

Answer:

The main substrate of chymotrypsin includes tryptophan, tyrosine, phenylalanine and methionine

Explanation:

1.

Histidine yields a proton to aspartate and recovers it from serine.

Seen in another way: aspartate captures a proton from the serine through histidine.

2.

a) The serine (deprotonated) is thus capable of attacking the peptide bond (nucleophilic carbonyl attack) and forms a tetrahedral intermediate; The substrate is thus covalently bound to the enzyme (now it is a transition state).

b) The peptide bond is broken and the released amino terminus (R) recovers a proton from histidine.

c) Histidine, in turn, recovers it from aspartic.

3.

a) Aspartate captures a proton of histidine again, so that it can capture it in turn from water.

b) This generates a hydroxide anion that attacks the ester intermediate between the serine and the carboxyl part (R ′) of the substrate peptide.

c) A new tetrahedral intermediate bound to the enzyme is formed (via serine residue).

4.

a) The carboxyl group of the peptide is regenerated, the serine being separated and the other peptide fragment being free (the R ′ part with a free carboxyl end)

b) The serine recovers the proton at the expense of histidine, which in turn captures it from aspartic acid.

c) The catalytic triad (Asp, His, Ser) has been regenerated in its original state.

The net reaction is:

R–NH – CO –R ′ + H2O ⟶ R– NH2 + HOOC –R ′ ⟶ R – NH3 + + −OOC –R ′

The active site or catalytic center of chymotrypsin is formed by several amino acid residues, among which the essential role corresponds to the "catalytic triad".

Explain blood curculation in human body in brief (in 100 words)​
bekas [8.4K]
Circulatory system pumps blood from the heart to the lungs to get oxygen. The heart then sends oxygenated blood through arteries to the rest of the body. The veins carry oxygen-poor blood back to the heart to start the circulation process over. Your circulatory system is critical to healthy organs, muscles and tissues.

Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms, including a high fever, headaches, and
monitta

Answer:

lytic, because of the quick onset of symptoms after infection

Explanation:

As seen in the question above, the SARS virus tends to develop symptoms very quickly when it is infecting a person. This speed in the development of symptoms is a characteristic of the lytic cycle, in relation to the reproductive cycle of viruses. This is because in the lytic cycle, a virus can infect many cells at once, which accelerates the development of the disease. This cycle allows the virus to use all of the cell's biological machinery to reproduce more copies of the virus. When these copies are ready, the virus causes the destruction of the host cell and the release of new viruses to other cells, where the whole process will be repeated. This is all done very quickly.

The lysogenic cycle does not cause the rapid infection of thousands of cells, since it is necessary that there is an adaptation between the DNA of the cell and the DNA of the virus. This slows down the infection process and, therefore, symptoms appear more slowly.
