ATP is:
- Nucleotide
- Nucleoside
- Nucleic acid
- Vitamin
The Correct Option is A
Solution and Explanation
ATP is a Nucleotide. ATP stands for Adenosine Triphosphate. It is composed of a nucleoside (adenosine) linked to three phosphate groups. Nucleotides are the basic building blocks of nucleic acids like DNA and RNA, but ATP primarily serves as a universal energy carrier in cells.
So, the correct option is (A): Nucleotide

Enzymes - Biology
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.
