How does atp form? why is it so important to the cell? ' (open answer)

Ans.

ATP (adenosine triphosphate) is complex organic biomolecule that provides energy to all living organisms. ATP is produced by a chemical reaction, in which an inorganic phosphate molecule binds with ADP (adenosine diphosphate) molecule.

ATP is important to the cells as it is considered as energy currency of the cell, which is required for various functions, performed by a living cell, such as chemical synthesis of compounds, muscle contraction, and propagation of nerve impulses.

the supermassive black hole is in the middle of the galaxy.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
