Introduction

An essay to describe the different ways in which organisms use ATP (25 marks) All living things, plants and animals, require a continual supply of energy in order to survive. The energy is used for all the processes which keep the organism alive. Some of these processes occur continually, such as the metabolism of foods, the synthesis of large, biologically important molecules, e.g. proteins and DNA, and the transport of molecules and ions throughout the organism . Other processes occur only at certain times, such as muscle contraction and other cellular movements currently used in strenous physical activity. Animals obtain their energy by phospharalation of foods stores, plants do so by trapping the sunlight using chlorophyll in a process known as photosythesis. However, before the energy can be used, it is first transformed into a form which the organism can utilise easily. ...read more.

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. ...read more.

Conclusion

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. ...read more.

    It is this latter point that is most significant when considering anaerobic respiration for it means that even if the aerobic pathway is blocked that cells will still yield a net gain (albeit not as great) of ATP molecules in order to continue doing cellular work.

    The lactic acid may be removed quickly when oxygen levels are restored. However if the organism is not anaerobic then further processes takes place and produce more ATP molecules. These processes take place in the mitochondria but the pyruvate molecule is too big and is broken down into acetyl coenzyme (Acetyl CoA, a two carbon molecule).
