Some of the materials that exit the blood can be returned to the blood
If one question/answer:
Blood is passed into the nephron and removed through the urethra.
Answer:
The correct answer is -
a. Protonation of the substrate.
b. Deprotonation of the amino acids in the enzyme active site.
c. Change in tertiary structure in extreme conditions.
Explanation:
During an enzyme assay, suboptimal pH is changed and affect the Vmax to decrease and this could take place due to various reasons such as-
A) protonation of the substrate - Upon protonating or adding a proton or hydrogen cation to a substrate atom, the mass and the charge of the species each increase by one unit which make a conjugate acid.
B) Deprotonation of the amino acids in the enzyme’s active site -Changing the pH will affect the charges on the amino acid molecules.
C) Denaturation of the protein’s tertiary structure- Tertiary structure of the protein is basically a backbone of peptide chain with one or more secondary domains of proteins that increasing the pH or decreasing the pH get denature.
Thus, the correct answer is : option A, B, C.
The answer is : C. Gravity
The Gravitional forces that the stars and planet have are different from one another. The difference in gravities All the stars and planets in our solar system create an effect in which the stars and planets are pulling each other according the force of their gravity, which create our current orbits in the syste
