Question

The quaternary structure of ovalbumin D Question 28 2 pts Denaturation, a process in which a protein loses its native shape and function, is likely to be caused by all of the following except being transported from one cell to another in a living organism. pH change. temperature change. ionic concentration change. increase in hydrogen ion concentration. 2 pts Question 29

Answer 1

Solution

Question 28

First Option is incorrect for protein denaturation and other second third fourth and fifth are correct regarding protein denaturation causes. Because

• when any protein transfer from one cell to another in living organism.so there is no chance to denature structure of protein.
• change in ph that is change in hydrogen ion concentration will change in the structure of amino acids as well as secondory tertiary and quarternary structure of protein.it will disrupts hydrogen bonding and electrostatic interaction.
• change in temperature also affect the denaturation.i e if we increases temperature then denaturation occure.
• change in ionic concentration leads to affect on charged amino acids and it will affect electrostatic interaction between amino acids.
• increase in hydrogen ion concentration is nothing but the increase in ph.as ph increases structure of amino acids as wel as secondory and tertiary structure will disrupts leads to denaturation of proteins.
