AP BIOLOGY

Detailed explanation-1: -Chemically ATP has 3 photosphate molecules along with a nitrogenous compound called adenine and a pentose sugar called ribose.

Detailed explanation-2: -Ribose is a type of sugar used by the body to make the energy-containing substance adenosine triphosphate (ATP). Intense exercise depletes muscle cells of ATP as well as the ATP precursors made from ribose, though these deficits are typically replaced within minutes.

Detailed explanation-3: -ATP is a single nucleotide made of a pentose sugar (ribose), a nitrogenous base, and three phosphate groups. It helps the cell to store and move energy.

Detailed explanation-4: -The molecule consists of three components: an adenine bicyclic system, a furanose ring, and a triphosphate chain. Two research groups reported the discovery of ATP in 1929.

Detailed explanation-5: -An ATP molecule consists of three parts (Fig. 1.7): adenine (a double ring of carbon and nitrogen), ribose sugar (five-carbon sugar), and three phosphate groups attached to ribose, which are linked by covalent bonds.
