ADP consists of adenosine which is composed of an adenine ring and a ribose sugar and two phosphate groups also known as diphosphate. This is vital to the flow of energy in biological systems. The breakdown of a phosphate group from ATP results in the release of energy to metabolic reactions.
These can be categorized into following subgroups,. ATP: ATP consists of adenosine an adenine ring and a ribose sugar and three phosphate groups triphosphate. As a result, they may have substantially different physical properties and different biochemical roles in the human body. Adenine attached to two phosphate groups is called adenosine diphosphate , i. ADP , and when it is attached to three phosphate groups it is called adenosine triphosphate , i.
Arijita S. Sep 29, ATP is a molecule with a lot of chemical energy. ATP stands for Adenosine Tri Phosphate , and that third phosphate is bonded to the other two with a very high energy bond, so a lot of energy is released when that bond is broken. With just 2 phosphates left, the molecule has much less chemical energy, because the high energy bond between the last 2 phosphates has been broken. Answer 1: This is a pretty sophisticated question. There are pictures of these molecules at: adenosine triphosphate.
Skip to content. ATP can be considered the potential energy, which is basically the stored energy used by a cell to do particular tasks. ADP can be considered kinetic energy, which is necessary for the flow of energy. It results in a release of free energy after the removal of one phosphate group.
Functions of ATP promotes active transport, the building of molecules, cellular functions like muscle movement, while ADP helps in catabolic reactions, activation of platelets etc.
