|
Denaturation (breaking chemical bonds of proteins) occurs by
|
|
adding acid
|
|
|
heat
|
|
|
mechanical agitation
|
|
|
trapping air bubbles
|
|
|
all of the above
|
Explanation:
Detailed explanation-1: -A protein becomes denatured when its normal shape gets deformed because some of the hydrogen bonds are broken. Weak hydrogen bonds break when too much heat is applied or when they are exposed to an acid (like citric acid from lemon juice).
Detailed explanation-2: -During the denaturation of proteins, the secondary and tertiary structures get destroyed and only the primary structure is retained. Covalent bonds are broken and interaction between amino-acid chains gets disrupted. This results in the loss of biological activity of the proteins.
