All about atp

The Nature of ATP Back to Top Adenosine triphosphate ATPthe energy currency or coin of the cell pictured in Figfures 1 and 2, transfers energy from chemical bonds to endergonic energy absorbing reactions within the cell. Structurally, ATP consists of the adenine nucleotide ribose sugar, adenine base, and phosphate group, PO plus two other phosphate groups. A 2-D stick view of the structure of ATP.

Every single thing you do depends on your bodies ability to produce ATP. Learn all about this fascinating molecule of energy by reading this page. Whether it's during a 42km marathon run or one explosive movement like a tennis serve, every single movement in the human body is powered by the breakdown of one chemical compound - adenosine triphosphate ATP.

ATP is essentially the energy currency of the body. An ATP molecule consists of one adenosine and three tri phosphate groups, as shown in the adjacent diagram. It results in the last phosphate group splitting away from the ATP molecule and releasing energy for muscle contraction and all other bodilly functions as shown All about atp diagram 2.

This enzyme has different forms, which contribute to either the breakdown of ATP or the manufacture synthesis of new ATP. The by-products of the breakdown of ATP are adenosine diphosphate ADPwhich is the remaining adenosine and two di phosphate groups, and one single phosphate Pi that is 'on its own'.

ATP Nutrition – Live The ATP Lifestyle

The body only stores a very small quantity of ATP within its muscles cells, enough to fuel only a few seconds of exercise. Because of this the body must constantly synthesise new ATP in order to constantly fuel movement and without being dramatic…survive!

If this occurs in the presence of oxygen it is called aerobic metabolism or 'oxidative phosphorylation' if we want to be really really technical. If it occurs without oxygen it is called anaerobic metabolism. Understanding how the body synthesises ATP is the key to understanding how the different energy systems work.

Phosphocreatine is also known as creatine phosphate All about atp like existing ATP; it is stored inside muscle cells.

However it is only stored in limited quantities and therefore like our ATP stores it also runs out very quickly. It is estimated that there is only about g of ATP and about g of phosphocreatine stored in the body, mostly within the muscle cells.

Because the stores of PC run out quickly other substrates that are stored in larger quantities in the body are also used to synthesize ATP. These include the sources gained from everyday foods that provide the following macronutrients: Fats Carbohydrate Carbohydrates are the bodies preferred source of food energy for the synthesis of ATP, with one gram of CHO providing four calories of energy.

Once digested carbohydrates are broken down into glucose and chemical reactions involving glucose then produce ATP.

Glucose is always present within the blood as it circulates and provides a readily available source of energy. Too much glucose in the blood is not healthy however as it becomes thick and sticky, making it harder to flow through small blood vessels.

So to ensure the blood glucose levels are healthy excess glucose that is not needed immediately to produce energy for the body is converted into a substance called glycogen and this is stored in the muscles and liver.

When needed, glycogen can then be converted back to glucose for energy. Fatty acids either circulate in the blood or are stored as triglycerides in adipose tissue and muscle. Fat is a very energy dense nutrient, one gram of it provides nine calories of energy.

Despite the large quantity of available energy that fat has it provides this energy at a much slower rate than carbohydrate.

This is because the chemical reactions required for its breakdown are much more complex and time consuming. Protein Protein contains four calories per gram and again provides energy at a much slower rate than carbohydrates.

Protein only makes a small contribution to energy production. However it can become a more significant energy source under periods of prolonged starvation or in ultra endurance events where other energy sources become severely depleted.

Protein is converted into amino acids. Amino acids are normally responsible for the growth and repair of body tissue but they can also be converted into glucose or into other substances used by the aerobic energy system to synthesise ATP.

It is important to note that an excess consumption of any or all of these food sources carbohydrates, fats or proteins does not result in more energy being produced, rather it results in the consumed excess being converted to and stored as adipose fat tissue.

There are three separate energy systems through which ATP can be synthesized, these are the: ATP-PC system also known as the phosphagen system Anaerobic glycolytic system also known as the lactate system Aerobic system also known as slow glycolysis or oxidative phosphorylation The ATP-PC system and anaerobic glycolytic system are both anaerobic systems, meaning that oxygen is not used by these systems to synthesize ATP.

The aerobic system on the other hand relies heavily on oxygen to synthesize ATP. Most exercise involves ATP being synthesized through a mix of all three systems. The factors that determine which system is most dominant at any time are the intensity and duration of exercise.

The diagram below is an example of the percentage contribution of energy provided by each system during the initial six minutes of a run. When exercise begins energy will come from the anaerobic energy systems, the initial 10 seconds or so are almost exclusively through the ATP-PC system.

As exercise continues the anaerobic systems become depleted due to the limited stores of ATP, PC and glycogen and the aerobic system becomes increasingly dominant as it can break down more complex fuels for energy such as fats and proteins as well as glycogen.

The higher the intensity of the exercise the quicker the anaerobic systems will be depleted.ATP Prize Money Leaders (US$) Rankings Date: Sep 17, Money Rank Player Career YTD Singles Doubles. ATP is the main source of energy for most cellular processes.
