Adenosine triphosphate (ATP) is a multifunctional nucleotide used in cells as a coenzyme. It is often called the "molecular unit of currency" of energy transfer. ATP transports chemical energy within cells for metabolism. It is produced by photo-phosphorylation and cellular respiration and used by enzymes and structural proteins in many cellular processes, including active transport, respiration, and cell division. One molecule of ATP contains three phosphate groups, and it is produced by ATP synthase from inorganic phosphate and adenosine diphosphate (ADP). ATP is used is many organisms and also in different ways. Below are a few ways in which ATP is used.
Oxidation of NADH and FADH2to H2O (and NAD or FAD). Generates H ion concentration gradient and therefore ATP.
In photosynthesis H+ ions are vital in the production of the energy source that is ATP, which is used in several metabolic processes, such as respiration. The photolysis of water produces H+ ions, electrons and O2. The excited electrons lose energy as they move along the electron transport chain, this energy is used to transport the H+ ions (protons) in to the thylakoid, which causes a higher concentration of H+ than there is in the stroma, thus causing a proton gradient across the membrane. The H+ then proceed to move down the concentration gradient into the stroma via the enzyme ATP synthase. The energy from this process is called chemiosmosis and combines ADP with inorganic phosphate (Pi) to form ATP. Light energy is then absorbed by photosystem I (PS I) which excites the electrons to a higher energy level. These electrons are transferred to NADP with H+ ions from the stroma to form reduced NADP. The whole of this process is
ATP is the main energy molecule in cells and has a unique function as an energy transferor. This molecule contains nitrogenous base adenine connected to three molecules of phosphorus. The last 2 phosphates are high energy bonds. When ATP releases the terminal phosphate, energy is released while forming a new compound ADP. ADP can be remade with another phosphate to form ATP again
It refers to the process of harvesting chemical energy (ATP) from organic molecules (food) into a form immediately usable by organisms. This process is happening all the time in the cytoplasm and mitochondria. The following equation is used during cellular respiration:
Adenosine Triphosphate (ATP) is a chemical compound formed to provide the body with energy. The molecule is made up of 1 adenosine molecule and 3 phosphate molecules which can be seen as; (A + P + P + P = ATP). The body obtains ATP from carbohydrates, fats and proteins and only small amounts of ATP can be stored in muscle cells, for about 10 seconds only. It only takes the body around 3 minutes to fully restore its ATP supply.
ATP is often referred to as the energy currency of life. The cells use a form of energy called ATP to power almost all activities, such as muscle contraction, protein construction, transportation of substrates, communication with other cells and activating heat control mechanisms. Adenosine Triphosphate (ATP), an energy-bearing molecule found in all living cells. Formation of nucleic acids, transmission of nerve impulses, muscle contraction, and many other energy-consuming reactions of metabolism are made possible by the energy in ATP molecules. The energy in ATP is obtained from the breakdown of foods.
All living cells require energy in order to proceed with cellular processes such as active transportation, and the synthesis of molecules. ATP (Adenine Tri-Phosphate) is a molecule, which provides energy in a form that cells can use for such cellular processes. Cellular
Introduction: Cellular respiration and fermentation are used in cells to generate ATP. All cells in a living organism require energy or ATP to perform cellular tasks (Urry, Lisa A., et al. , pg. 162). Since energy can not be created (The first law of thermodynamics) just transformed, the cell must get its energy from an outside source (Urry, Lisa A., et al. , pg.162). “Totality of an organism’s chemical reactions is called metabolism” (Urry, Lisa A., et al., pg. 142). Cells get this energy through metabolic pathways, or metabolism. As it says in Campbell biology, “Metabolic pathways that release stored energy by breaking down complex molecules are called catabolic pathways” (Urry, Lisa A., et al. pg.
This energy is used to re-form the bonds between ADP and P to make ATP.
Cellular respiration is creating ATP from ADP and a phosphate inorganic using the energy which was released from breaking apart glucose. The equation that summarizes this process is (ADP + Pi) + C6H12O6 +6O2 → 6H2O + 6CO2 + heat + (ATP). ATP is made up of a sugar ribose, 3 phosphate groups, and adenine. ATP is the energy used to complete processes in the body. ATP also has a very high potential energy because of its phosphate groups. Potential energy has to do with energy due to location. For example, a person on a diving board has a higher potential energy than a person already in the water. This is because the girl on the diving board has more potential to fall or convert the potential energy into kinetic energy by using her location to power her fall. The ATP has higher potential energy because its phosphate groups have oxygen ions. The negatively charged oxygen ions repel each other and do not want to be near to one another. Because of this, if the third phosphate group was to break off of the ATP molecule, an amount of energy would be released, lowering the potential energy. This is why ATP has such a high energy and is used for so many processes. The ATP would become ADP with a phosphate group becoming inorganic and would release energy.
ATP-PC - Adenosine triphosphate (ATP) is the usable form of chemical energy for muscular activity. It is stored in most cells, particularly in muscle cells. Other forms of chemical energy, such as that available from the foods we eat, must be transferred into ATP form before they can be utilized by the muscle cells.
ATP is used in all three systems, phosphagen, anaerobic, and aerobic as the primary energy source. How ATP is processed, used and renewed will depend on the speed, intensity and duration in contractions of our muscles.
Cellular respiration is a procedure that most living life forms experience to make and get chemical energy in the form of adenosine triphosphate (ATP). The energy is synthesized in three separate phases of cellular respiration: glycolysis, citrus extract cycle, and the electron transport chain. Glycolysis and the citric acid cycle are both anaerobic pathways because they do not bother with oxygen to form energy. The electron transport chain however, is aerobic due to its use of oxidative phosphorylation. Oxidative phosphorylation is the procedure in which ATP particles are created with the help of oxygen atoms (Campbell, 2009, p. 93). During which, organic food molecules are oxidized to synthesize ATP used to drive the metabolic reactions necessary to maintain the organism’s physical integrity and to support all its activities (Campbell, 2009, pp. 102-103).
