What is the catalytic triad of chymotrypsin, a type of serine protease? the enzyme-cofactor-intermediate complex the amino acids
VashaNatasha [74]

Answer:

The correct answer is: Serine, Histidine, Aspartate

Explanation:

The catalytic triad of an enzyme is composed of three aminoacid residues which are the most important for its catalytic activity. They are located in the catalytic site of the enzyme. In the case of chymotrypsin- a serine protease, the catalytic triad is composed by serine, histidine and aspartate (Ser-His-Asp). Serine proteases hydrolyse peptidic bonds in proteins and peptides. To do that, the histidine-which interacts with the aspartate by a hydrogen bond so its pKa increases- take a proton from the serine. Thus, deprotonated serine is able to attack the peptide bond and to perform hydrolysis.

N which changes of state do atoms lose energy? Check all that apply.
Alex73 [517]
When liquid state is being converted to solid state, atoms come closer to each other and their speed of movement also decreases. Instead of moving about in the substance, they are only able to vibrate about their positions in solid. Hence, this change leads to loss of energy. Similarly, atoms loose energy when state changes from gas to liquid.

How do electrons enter an orbital​
Hoochie [10]

Answer:

Electrons that occur together in an orbital are called an electron pair. An electron will always try to enter the orbital with the lowest energy. ... In other words, within one energy level, electrons will fill an s orbital before starting to fill p orbitals. The s subshell can hold 2 electrons.
