The most important process that atp is used with is respiration. This process allows animals and plants to convert chemical energy to chemical potential energy. the first step of respiration is glycolysis.the process converts glucose in to puruvic acid which needs 2 molecules of atp to iniate the reaction and consequently produces 4 molecules of atp. Thus produces a net gain of 2 molecules of atp. Pyruvic acid is converted furthur to acetylcoenzyme A, which is used to produce atp in the krebs cycle. Every turn of the citrus cycle 1 molecule of atp is produced. furthus more a lot atp is produced as electrons move across a electron tranfer chain in the final stage of respiration. chemical potential energy is transfered to Atp, as atp acts as more usefull immediate source of energy. Atp can be broken down in one single reaction to to produce inorganic phosphate and adenosine di phosphate. therefore it can provide energy instantanouesly. Unlike glucose which takes which takes several reactions to produce carbon dioxide and water. Another reasons that atp is used for fuelling he energy required reactions in he body is because atp provides a small but adeqate amount of energy. therefore atp acts more effeciently as glucose wil produce more energy than required.
Atp is also used with photosynthesis of plants, which consists of the absorption of light by chlorophyll pigments and conversion of this light to chemical energy.This occurs in organelles called chloroplasts on membrane systems known as thylakoids. Respiration reverses the process of photosynthesis, releasing the stored chemical energy. light is need to excite the photosystems that acts a primary pigment molecule, which cause two electrons to be raised. . the electrons that have been raised pass on to an electron acceptor , losing energy as they do , whch subsequently produces ATP. The Atp used is needed in the light independent reaction with the aid of reduced NADP to convert glycerate-3-phosphate to triose phosphate. whch the the plants can use as a source of nutrition.
However to gain nutrients from the soil, such as nitrates, Na+ ions which are essential for growth plants need top use a process called active transport which is fulled by ATP. Active transport requires energy to enable the cell in moving molecules against a concentration gradient. Active transport enables a cell to maintain a lower concentration of sodium inside the cell, and also enables a cell to accumulate certain nutrient inside the cell at concentrations much higher than the extracellular concentrations.
Other uses of atp that is produces an instant source of energy whch works with the muscle fibres to produce a contraction. Myosin ATPase produces contractile force from the energy released from ATP hydrolysis. ATP binding to myosin causes of the myosin "head" from actin. After release, the energy from ATP hydrolysis is stored in the myosin and released to cause contraction when myosin again comes in contact with actin. Myosin kinetics and the previous diagram help us to understand the cycle of active contraction, the relaxed state, and the development of rigor:
to conclude atp is an essential source of energy, and its uses are wide and vary from the protien synthesis to nitrogen fixation, which ia also an energy requiring process; have led to farmars increasing supplies of phosphate fertilizer, since phosphate fertilizer is used to make adenosine triphosphate (ATP), an energy-rich substance.which in turn alow nitrogen fixing plants the energy neccary to fix inert N2 into nitites and subsequentaly provideing nitrates to the soil. which reinforces the importance of this complex substance; Adenosine triphosphate.
contains; a ribose (the same sugar that forms the basis of DNA). Attached to one side of this is a base (a group consisting of linked rings of carbon and nitrogen atoms); in this case the base is adenine. The other side of the sugar is attached to a string of phosphate groups. These phosphates are the key to the activity of ATP.
