AP BIOLOGY

Detailed explanation-1: -process, ATP is degraded to adenosine diphosphate (ADP), a molecule with only two phosphate bonds. To recharge the molecule by adding the third phosphate group requires energy derived from the breakdown of foodstuffs, or substrates.

Detailed explanation-2: -ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atom of ribose. The diphosphate group of ADP is attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon.

Detailed explanation-3: -The ADP molecule shows two phosphates, whereas the ATP molecule comprises three phosphates. ADP stands for adenosine diphosphate. As the name suggests, it consists of two phosphate groups that form a bond with the ribose molecule.

Detailed explanation-4: -Adenosine diphosphate (ADP) is a nucleoside phosphate comprised of a ribonucleoside and two phosphate groups. It means it has a ribose as its sugar and two phosphate groups attached. Its nucleoside contains a purine base, i.e. an adenine attached to the ribose sugar.

Detailed explanation-5: -ADP or adenosine diphosphate is composed of one adenine molecule, a ribose sugar and two phosphate groups.
