Many trace elements serve as essential co-factors for enzymes, which are biological catalysts that facilitate chemical reactions within cells. These trace elements are required in small quantities but play crucial roles in various biochemical processes, often by assisting enzymes in their catalytic functions.
So, the correct option is (A): co-factors of enzymes
Given below are two statements:
Statement I: In prokaryotes, the positively charged DNA is held with some negatively charged proteins in a region called nucleoid.

Enzymes are proteins that help accelerate metabolism or the chemical reactions in our bodies. They build some substances and decompose others. All living creatures have enzymes.
Our bodies naturally build enzymes. But enzymes are also in mass produce products and food.
One of the most important roles of enzymes is to succor digestion. The process of turning the food that we eat into energy is called digestion. For instance, there are enzymes in our saliva, pancreas, stomach, and intestines. They decompose fats, proteins, and carbohydrates. Enzymes make use of these nutrients for growth and cell repair.
