The definition of ATP in biology. ATP or adenosine triphosphate is the energy-carrying molecule essential for all living organisms. It is used to transfer the chemical energy necessary for cellular processes. Adenosine triphosphate (ATP) is an organic compound that provides energy for many processes in living cells.

Get a quoteGlycogen, a polymer of glucose, is a short-term energy storage molecule in animals ( Figure 9.9.1 9.9. 1 ). When there is plenty of ATP present, the extra glucose is converted into glycogen for storage. Glycogen is made and stored in the liver and muscle. Glycogen will be taken out of storage if blood sugar levels drop.
Get a quoteEnergy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis. Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation. The key steps of this process, shown in simplified form in the diagram above, include:

Get a quoteATP Structure and Function. The core of ATP is a molecule of adenosine monophosphate (AMP), which is composed of an adenine molecule bonded to a ribose molecule and to a single phosphate group. Ribose is a five-carbon sugar found in RNA, and AMP is one of the nucleotides in RNA. The addition of a second phosphate group to this core molecule ...
Get a quoteThrough the production of ATP, the energy derived from the breakdown of sugars and fats is redistributed as packets of chemical energy in a form convenient for use elsewhere in the cell. Roughly 10 9 molecules of ATP are in solution in a typical cell at any instant, and in many cells, all this ATP is turned over (that is, used up and replaced) every 1–2 minutes.

Get a quoteAerobic Respiration (with oxygen again) Within two minutes of exercise, the body starts to supply working muscles with oxygen. When oxygen is present, aerobic respiration can take place to break down the glucose for ATP. This glucose can come from several places: remaining glucose supply in the muscle cells. glucose from food in the intestine.
Get a quoteUpdated on May 09, 2019. Adenosine triphosphate or ATP is often called the energy currency of the cell because this molecule plays a key role in metabolism, particularly in energy transfer within cells. The molecule acts to couple the energy of exergonic and endergonic processes, making energetically unfavorable chemical reactions able to …

Get a quotePhotosynthesis takes place in two stages: light dependent reactions and the Calvin cycle. Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO 2.
