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

- RNA interference
- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

- Two gases A and B are filled at the same pressure in separate cylinders with movable pistons of radii \(r_A\) and \(r_B\) respectively. On supplying an equal amount of heat to both the cylinders, their pressures remain constant and their pistons are displaced by 16 cm and 9 cm respectively. If the change in their internal energies is the same, then the ratio \(r_A / r_B\) is:

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.
