Adenosine triphosphate (ATP) is a nucleotide which is also called as nucleoside triphosphate is a small molecule used in cells as a coenzyme. It is often referred to as the "molecular unit of currency" of intracellular energy transfer. ATP transports chemical energy within cells for metabolism. Most of the cellular functions need energy in order to be carried out such as synthesis of proteins, synthesis of membranes, movement of the cell, cellular division, transport of various solutes etc. The ATP is the molecule that carries energy to the place where the energy is needed. When ATP breaks into ADP (adenosine diphosphate) and Pi (phosphate), the breakdown of the last covalent link of phosphate liberates energy that is used in reactions where it is needed.

In nuclear reactor the speed of neutrons is slowed down by heavy water.

The IUPAC name of the given compound is Propyne. It is also known as Methyl acetylene. It contains three carbons and one triple bond (alkyne). It is also called Prop-1-yne because the triple bond is present at first carbon.

Out of P (Phosphorous), S(Sulphur), Cl(chlorine), F(Fluorine), P will be having the least negative electron gain enthalpy.

This is due to the fact that P comes before S, Cl, F in the periodic table. Therefore, it will be having a little bit bigger size with decreased nuclear charge. Thus it will show lesser attraction towards electrons.

The alpha-particles are double positively charged helium nuclei.

Sulphuric acid is called the King of Chemicals because it is used in the preparation of a very large number of other useful chemicals such as hydrochloric acid, nitric acid, dyes, drugs etc. In fact the annual production of shulpuric acid in a country is a measure of the economy of the country.

Blood is a natural colloid.

Here the most stable carbocation is the 2.

The particle with 13 protons and 10 electrons is Al3+ ion.
