Select the true statements about denaturation. a. Denaturation and digestion refer to the same process.
b. Denaturation of an enzyme will cause a loss of its catalytic activity.
c. A zymogen is a denatured form of a proteolytic enzyme.
d. Egg white meringue contains denatured egg white proteins.
e. A denatured protein has a different tertiary structure than its native state.
f. Protein denaturation involves cleavage of its peptide bonds.

The correct options are: Denaturation of an enzyme will cause a loss of its catalytic activity.

Egg white meringue contains denatured egg white proteins.

A denatured protein has a different tertiary structure than its native state.

 Protein denaturation involves cleavage of its peptide bonds.

Explanation:

Protein denaturation is the breakdown of tertiary or quaternary junctions of proteins, which are the easiest to break compared to primary and secondary.

Denaturation can arise due to a change in pH or due to excess temperature. An enzyme is generally a protein and if it is subjected to acidic acids or high temperatures, it denatures, ceasing to perform its function.

Zymogen is a non-denatured INACTIVE proenzyme, that is why we consider that option false along with those that were not selected.

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form() .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.
