Answer:
The effect of protein disulfide isomerase on insulin signifies that the active conformation of insulin is not the most thermodynamically favored form. The main reason behind this is that the protein disulfide isomerase seems to decline the free energy, that is, it makes them more steady form predominant.
In the case of insulin, the prevalence of the stable form results in its inactivation. Thus, it signifies that the active form is not thermodynamically stable.
Its the second option....................................... :)
4 is the correct answer hope you get it right!!!
Epigenetics is the study of how the structure and function of genes interact with our environment to influence behavior.
In addition to your surroundings and habits, such as what you eat and how much exercise you get, your genes play a significant part in determining your health. The field of epigenetics investigates how environmental factors and behavior may alter how your genes function. Gene-environment interactions that result in the expression of different phenotypes throughout development are the basis for the initial usage of the term "epigenetics." To turn on or off the genes that cause long-lasting alterations linked to the differentiation of various cell types, epigenetic processes are frequently used.
Epigenetics is the study of how DNA sequences are maintained as genes are controlled by cells. DNA alterations known as epigenetic changes control whether or not genes are activated.

Enzymes (Catalysts) lower the required activation energy, allowing the reaction to happen more quickly.
