• D. P\(_N\) \(\xrightarrow{\Delta}\) P\(_D\) \(\rightleftharpoons\) P\(_A\) \(\xrightarrow{\nabla}\) P\(_G\)

Hint:

During egg-white gel formation, the proteins undergo denaturation with heat, followed by aggregation, ultimately leading to the formation of a gel-like structure.

Answer 1

The Correct Option is B

The formation of egg-white gel involves a sequence of events where proteins undergo denaturation and aggregation due to heating:
- \(\mathbf{P_N}\) represents the native protein. Initially, the egg-white proteins are in their native form.
- \(\mathbf{P_D}\) represents the denatured protein, which occurs when heat is applied to the egg-white proteins, causing them to unfold.
- \(\mathbf{P_A}\) is the aggregated protein, which forms as denatured proteins begin to interact and aggregate with each other. This aggregation starts to form the gel-like structure.
- \(\mathbf{P_G}\) represents the protein gel, which is the final product after sufficient aggregation of the proteins.
The correct sequence is: Denaturation of native proteins (\(\mathbf{P_N}\)) leads to the formation of denatured proteins (\(\mathbf{P_D}\)), which then aggregate (\(\mathbf{P_A}\)) and finally form the gel structure (\(\mathbf{P_G}\)). Thus, the correct answer is (B) P\(_N\) \(\rightleftharpoons\) P\(_D\) \(\xrightarrow{\Delta}\) P\(_A\) \(\xrightarrow{\nabla}\) P\(_G\).
