ATP consists of adenosine and two inorganic phosphates. True False. ATP is synthesized by the cell through cell respiration. In the absence of oxygen, respiration occurs in the following steps: Glycolysis, Kreb's Cycle, and Cytochrome System. Plants no longer need cell respiration because they produce food through photosynthesis.

Skeletal muscles require large amounts of energy for mechanical work, so muscle cells contain more mitochondria than the cells of other tissue types. A full-time writer since , David Dunning is a professional freelancer specializing in creative non-fiction.

When the chemical bonds within ATP are broken, energy is released and can be harnessed for cellular work. The more bonds in a molecule, the more potential energy it contains. Because the bond in ATP is so easily broken and reformed, ATP is like a rechargeable battery that powers cellular process ranging from DNA replication to protein synthesis. Adenosine triphosphate ATP is comprised of the molecule adenosine bound to three phosphate groups.
Adenosine is a nucleoside consisting of the nitrogenous base adenine and the five-carbon sugar ribose.
The three phosphate groups, in order of closest to furthest from the ribose sugar, are labeled alpha, beta, and gamma. Together, these chemical groups constitute an energy powerhouse.
