The oxidation of carbohydrates and fats in an organism creates several chemical reactions that release enough energy to turn one molecule of ADP into approximately 150 molecules of ATP by adding phosphate groups to the m... More »

The energy used by an organism is called ATP. Part of its makeup is three phosphates. When one of these breaks off, energy is released and ADP is formed. More »

Organisms need to carry out respiration to convert glucose to usable energy. When organisms consume food, the body targets glucose molecules for conversion to energy. However, respiration must first occur to transform th... More »

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 ri... More »

Adenosine triphosphate (ATP) is converted to adenosine diphosphate (ADP) in the cells of plants and animals when energy is required to power processes in the cell. ATPase, an enzyme, cleaves one of the phosphate bonds on... More »

The process that uses high energy electrons to convert ADP to ATP is known as oxidative phosphorylation. ATP, or adenosine triphosphate, is the molecule that provides the energy cells need to function. More »

Adenosine diphosphate becomes adenosine triphosphate when a phosphate molecule is bonded to it. ADP has two phosphate groups, and when an additional phosphate group is added, it becomes ATP. More »
