ADP is the abbreviation for adenosine 5'-diphosphate, a molecule involved in energy transfer within cells and with regulation of clot formation in the blood. It consists of an adenine ring, a ribose sugar and two phosphate groups.Continue Reading
Adenosine 5'-diphosphate is formed when adenosine 5'-triphosphate (ATP) is hydrolyzed to form ADP plus a free phosphate group. This is a spontaneous or exergonic reaction which releases energy that the cell then uses to drive nonspontaneous reactions.
ADP also plays an important role in hemostasis, the normal process of blood coagulation to stop bleeding when an injury occurs. Platelets in the blood will stick to the walls of blood vessels when a vessel is injured. The platelets then release several chemicals — including ADP — to regulate the coagulation process. ADP causes additional platelets in the blood to change shape and stick aggressively to the growing clot, increasing its size and strength. ADP also induces fibrinogen fibers to stick to and reinforce the clot.Learn more about Cells
Aerobic respiration is a chemical reaction that requires oxygen to generate adenosine triphosphate, or ATP, a chemical that cells use for energy. It is also referred to as intracellular energy transfer.Full Answer >
ADP is an organic compound that is essential for the transfer of energy during photosynthesis. ADP is composed of a five carbon atom compound known as ribose, one adenosine molecule and two phosphate groups. It is formed by removing one phosphate from adenosine triphosphate, ATP.Full Answer >
ATP contains three phosphate groups, whereas ADP contains two. ATP stands for "adenosine triphosphate," and ADP stands for "adenosine diphosphate." They both contain the nitrogenous base adenine, the five-carbon sugar ribose and several phosphate groups.Full Answer >
Cells capture the energy released by cellular respiration in adenosine triphosphate, commonly abbreviated as ATP. ATP is the main energy currency of all cells, or the molecule that carries the energy needed for all the chemical reactions the cell performs.Full Answer >
