Assignment: How ATP/PC System Works

There are three main energy systems used in a game of touch football which consist of the creatine phosphate (ATP PC) system, lactic acid system and the aerobic system. Each system plays a vital role during game play. Every muscle in your body requires energy to perform all movements, and to do this, the energy is produced by the breakdown of a molecule called adenosine triphosphate (ATP). ATP is found in all cells which is a chemical form of muscular activity and performs mostly all functions in the human body. It contains 3 phosphate groups and adenosine. ATP is stored in the muscles and lasts for approximately 10-30 seconds. Carbohydrates, fats and proteins, are all producers of ATP from the food we eat; however Creatine Phosphate is

The way that creatine works in the body is very astonishing. When the molecule ATP or adenosine triphosphate is broken down into ADP or adenosine diphosphate and phosphate, energy is released from the exothermic reaction for our body to have intense movements. The energy that is released is the decomposition of the single Phosphorus. Creatine synthesizes another phosphorus to turn ADP back into

The Creatine supplement most commonly used is Creatine Monohydrate (C4H11N3O3). There are other derivatives of this supplement. Creatine Monohydrate has a variety of influences on athletes. Creatine’s occupation is to raise the rate at which ATP (Adenosine Triphosphate) is produced (Creatine Monohydrate Supplementation). When a muscle is used an ATP molecule goes through hydrolysis, the breaking of a chemical bond using H20. The muscle uses this breaking down of ATP to release energy. The ATP gives off an ADP (Adenosine Diphosphate) molecule. Due to the reliability of ATP breaking down with a water molecule, the amount of ATP available in the muscle cells is increased. At the same time ATP is being converted into ADP, ADP is being changed back to ATP inside the muscle. During the contraction of the muscle, the changing back of ADP to ATP is achieved by the Creatine already present in the cells. However, this rebuilding of ATP is not a direct result of the use of the Creatine in the cellular complex. Right upon the taking of Creatine Monohydrate, the total muscular capacity levels of phosphocreatine (PCr) and Creatine Monophosphate increase. This elevation of phosphocreatine “shifts the equilibrium towards the production of ATP,” allowing ATP to be generated at a much faster rate ( Muscle and Strength Magazine). This is the chemistry behind what Creatine does to your body and the reactions

Since the ATP vitality utilized by your muscles is produced with the guide of oxygen, it takes after that an expansion in exercise force will bring about an increment in muscular oxygen requests. Accordingly, more intense exercise relates to an expanded VO2. This is the reason that you're breathing gets continuously quicker and more profound as your exercise force expands, your body is attempting to give more oxygen to your working muscles with the goal that they can produce enough ATP vitality to keep you

Usually relying on ATP production for energy is alright except for two problems. The first is that ATP is produced at a slow rate, too slow to supply the energy needed to run a 200-meter sprint, for example. The second problem is that ATP production takes a while to get started. As one goes from rest at the starting line of a race to running at race speed, for example, the traditional method of ATP production does not begin working at full capacity until a couple of minuets have passed. Another source of energy is therefore needed to get one through the early moments of a race or workout. (http://www.creatine.com/creatine.html#source)

ATP-PC system has the highest rate of the 3 systems, it provides more energy in a short interval of time because it produces ATP more quickly than any other system. Its downfall however is that it burns out very quickly, meaning has a short and limited capacity of storage.

In these experiments we talked about the Resting Metabolic Rate and Progressive Submaximal Exercise Testing to determine a subjects’ carbon dioxide production to oxygen consumption. This was done by having examples provided for us to calculate the RMR by using a formula, (X ml/kg/min x weight in kg) / 1000 mL= # L/min, to determine the number of calories burned at rest, as well having subjects perform the standardized treadmill test for 12-15 minutes for the Progressive Submaximal Exercise Testing.

stored in all cells, particularly muscles. Only from the energy released by the breakdown of this compound can the cells perform work. The body is capable of resynthesising ATP to continue producing energy. For this to be able to happen within the body it must use the energy and reverse the equation: ATP = ADP + Energy.

If we suddenly begin sprinting, the ATP has to resynthesise very quickly. The quickest way is a chemical reaction that uses creatine phosphate (CP) which is found in the muscle cell. There is only enough CP to resynthesise ATP for about 10 seconds. It takes several minutes of rest or low

What sport do you play? What are the primary movements involved in your sport? Also, what intensities does your sport consist of? When thinking critically about the sport or activity you play these last two questions are important questions to ask yourself if you want to train efficiently and effectively to be the best athlete you can be. The type of movements and intensities your sport requires is directly related to the topic of bioenergetics, or the production of usable energy from important nutrients such as carbohydrates, proteins, and fats. Your body uses these nutrients or food we eat and converts it into an important molecule called, adenosine triphosphate (ATP). It is the production of ATP that allows muscular action to occur. However ATP can be produced in three main

The amount of ATP in the cells stay constant when physical activities increase. In the lab, students are experimenting their pulse rate in beats/min through three physical activities. An observation that is noticed is how everyone breathed really hard when they are faking to jump rope in the third activity. In addition, the average pulse rate for the relaxation activity is 60, the moderate activity is 121, and the intense activity is 155. As displayed in figure 1, the trend of the first bar and second bar double as the intensity of the activity increases. When performing an intense activity, the body requires an abundance of oxygen to produce energy which is also ATP. That process is called cellular respiration which uses glucose and oxygen

The body does not switch from the Lactic Acid Energy System to the ATP-PC system at exactly 2 minutes rest between sets. For some people it will be sooner and for some it will be later. Either way, it is not a sudden change, but rather a gradual changing of the guard with the Aerobic Energy System helping to bridge the gap between the two.

phosphocreatine stores.It takes 2-3 minutes and stores are 50% of normal level after 30 seconds of

ATP is an energy carrying molecule and it is found in the cells of living things, the ATP would capture the chemical energy that comes from the breakdown of food molecules and it releases the fuel to the other cellular processes, the cells need chemical energy to take away metabolic reaction that would not work automatically, it would also transport substances that are needed across the membranes and does mechanical work like moving muscles, an ATP does not store molecules for chemical energy because the carbohydrates like glycogen and fats do that, energy is needed by the cell and is converted from stored molecules in the ATP and then it delivers energy to the areas in the cell that need energy to do their daily

ATP is universal form of free energy in all living organisms and is an energy coupling agent (Tymoczko et al. 2013. p. 250). When ATP is hydrolyzed to produce adenosine diphosphate (ADP) and orthophosphate (Pi), or to adenosine monophosphate (AMP) and Pi, free energy is liberated. This free energy can then be utilized for endergonic reactions that need an input of free energy in order to occur. The recycling of ATP/ADP is critical to for energy exchange in living organisms. Thermodynamically unfavorable reactions can be driven if they are coupled to ATP hydrolysis in a new reaction.
