What produces ATP energy in a cell?
Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.
What function produces ATP?
ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen.
How is energy captured in ATP?
Energy is stored in the bonds between the phosphate groups (PO4-) of the ATP molecule. When ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, energy is released. When ADP and inorganic phosphate are joined to form ATP, energy is stored.
How do organisms generate ATP in the absence of oxygen?
Fermentation. Some organisms are able to continually convert energy without the presence of oxygen. They undergo glycolysis, followed by the anaerobic process of fermentation to make ATP.
What kind of energy is produced in the cell?
ATP, adenosine triphosphate, is the storage molecule for energy that is used in all living things. In our own cells, it is produced during anaerobic and aerobic respiration. Become a Study.com member to unlock this answer!
How does ATP function as an energy carrier?
Understanding the chemistry behind these questions will lead us to a more thorough understanding of how cells are able to conduct the business of living. The molecule ATP functions as an energy carrier. Adenosine triphosphate (ATP)is composed of the nitrogenous base adenine, the sugar ribose, and three phosphate groups (Figure 1).
How does hydrolysis of ATP work in a cell?
On its own, the hydrolysis of ATP would simply result in organisms overheating because the dissipation of energy would excite nearby molecules, resulting in heat (thermal energy). For energy to be useful in a cell, it needs to be linked to other processes.
How is ATP used during energy-coupling reactions?
By coupling the release of energy that occurs during ATP hydrolysis with changes in protein conformation, the breaking and forming of chemical bonds, and other reactions that require energy, the cell can perform nearly all of the tasks it needs to function.
