I think it's number 4 for 5 and its 3 for 6
False because zooming in makes it seem bigger so you can see more details. Zooming out would make it look farther away than what it really is
Physical anthropology, sometimes also called biological anthropology studies the biological features of human beings, such as morphological features, hair color, height, skin color etc. Besides that, it also studies the biological foundation of human behavior and adaptations of our species to the environment.
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.
