P7 – describe the three different energy systems and their use in sport activities
ATP stands for Adenosine triphosphate. It is an important question in sports training because all energy production is powered by this. The training programs that are designed for you or others will target you’re ability to produce energy for power and endurance.
ATP is often referred to as the energy currency of life. The body’s cells use a special form of energy called adenosine triphosphate to power almost all their activities, such as muscle contraction, protein construction, and transportation of substrates, communication with other cells, activating heat control mechanisms, and dismantling damaged and unused structures.
The alactic system is a form of training

Glycolysis is the breakdown of carbohydrates.
The process of lactic acid removal takes approximately one hour, but this can be accelerated by undertaking an appropriate cool down that ensures a rapid and continuous supply of oxygen to the muscles.
The aerobic energy system utilises fats, carbohydrate and sometimes proteins for re-synthesising ATP for energy use.
The aerobic system produces far more ATP than either of the other energy systems but it produces the ATP much more slowly, therefore it cannot fuel intense exercise that demands the fast production of ATP.
While the aerobic system doesn’t produce nearly as much power as the other systems, a major feature is its capacity which is virtually limitless, as it just keeps on producing ATP. This is why it is good for long distance events such as a marathon runner like Mo Farah.
The aerobic system consists of three processes each of which produce ATP. These stages involve more complex chemical reactions than the other energy systems which is why ATP production is much slower. These stages are; Aerobic glycolysis (slow glycolysis), Krebs cycle (also known as the citric acid cycle) and the Electron transport
gars. These are then split into two three-carbon sugar phosphates and then these are split into two pyruvate molecules. This results in four molecules of ATP being released. Therefore this process of respiration in cells makes more energy available for the cell to use by providing an initial two molecules of ATP.
In this lab, we explored the theory of maximal oxygen consumption. “Maximal oxygen uptake (VO2max) is defined as the highest rate at which oxygen can be taken up and utilized by the body during severe exercise” (Bassett and Howley, 2000). VO2max is measured in millimeters of O2 consumed per kilogram of body weight per min (ml/kg/min). It is commonly known as a good way to determine a subject’s cardio-respiratory endurance and aerobic fitness level. Two people whom are given the same aerobic task (can both be considered “fit”) however, the more fit individual can consume more oxygen to produce enough energy to sustain higher, intense work loads during exercise. The purpose of this lab experiment was performed to determine the VO2max results of a trained vs. an untrained participant to see who was more fit.
Aerobic energy system is a type of energy system and we use it when we are exercising at a low intensity and this is when your body has finished using both our apt-pc system and lactic acid, therefore it lasts longer then both of them and it kicks off after lactic acid which about the 3 minutes into exercising.
Do you know how you are able to run long distances or lift heavy things? One of the reasons is cellular respiration. Cellular respiration is how your body breaks down the food you’ve eaten into adenosine triphosphate also known as ATP. ATP is the bodies energy its in every cell in the human body. We don’t always need cellular respiration so it is sometimes anaerobic. For example, when we are sleeping or just watching television. When you are doing activities that are intense like lifting weights or running, your cellular respiration becomes aerobic which means you are also using more ATP. Cellular respiration is important in modern science because if we did not know about it, we wouldn’t know how we are able to make ATP when we are doing simple task like that are aerobic or anaerobic.
It is the slowest working metabolic pathway for the production of energy in the body. This cycle, unlike the energy consumption in sprinting, allows the body to maintain its energy level during endurance activities. The citric acid cycle, or the Krebs cycle, allows humans to sustain long-term energy (long running) because it produces more energy than the other pathways. The Krebs cycle uses lots of enzymes, which reduce the amount of energy required for a chemical reaction. These enzymes help the body use less and create more energy. By using enzymes in the absence of more energy, the Krebs cycle is different from other metabolic pathways. Through the catabolism of fats, sugars, and proteins, an acetate is created and used in the citric acid cycle. The Krebs cycle converts NAD+ into NADH. These are then used by another system called the oxidative phosphorylation pathway to generate
However, in anaerobic respiration (glycolysis and fermentation) only two (2) adenosine triphosphate (ATP) can be obtained. Now, for photosynthesis it is actually a carbon-fixation which is 3CO2+9ATP+6NADPH+H2O--- glyceraldehyde3phosphate+8Pi+9ADP+6NADP which turns out to just be eight-teen (18) ATP per glucose molecules in
Humans, and all animals, use adenosine triphosphate (ATP) as the main energy source in cells. The authors of Biological Science 5th edition said that “In general, a cell contains only enough ATP [adenosine triphosphate] to last from 30 seconds to a few minutes”. It is that way “Because it has such high potential energy, ATP is unstable and is not stored”. They also state that “In an average second, a typical cell in your body uses an average of 10 million ATP molecules and synthesizes [makes] just as many”. In the human body trillions of cells exist. The average human body uses and makes 10,000,000,000,000,000 molecules of ATP every second. In one minute the human body uses 600,000,000,000,000,000 molecules of ATP. In one day the human body uses 864,000,000,000,000,000,000 molecules of ATP. In one year, this is equivalent to 365.25 days; the average human body uses and makes a huge amount, 315,576,000,000,000,000,000,000 molecules of ATP. For this example one mile is equal to one molecule of ATP. Light travels at approximately 186,000 mi/sec. It would take light roughly 53,763,440,860 years to travel that many miles. The sheer amount of ATP made in the cells of people is amazing! This essay will explain somewhat the main way of making all of those ATP molecules in aerobic organisms, aerobic cellular respiration. There are four steps that take place in aerobic cellular respiration, and they are: 1.Glycolysis; 2. Pyruvate Processing; 3. Citric Acid Cycle; 4. Electron Transport and Oxidative Phosphorylation (Allison, L. A. , Black, M. , Podgoroski, G. , Quillin, K. , Monroe, J. , Taylor E. 2014).
As previously mentioned, enzyme catalyzed reactions are a large contributing factor to many biological systems. In regards to metabolic pathways, ATP Synthase is a necessary enzyme that uses a concentration gradient to attach a phosphate group to an ADP molecule. This process is called phosphorylation. The bond that is created between the ADP and the phosphate group is formed by dehydration synthesis. This enzyme appears at the end of the electron transport chain in cellular respiration and at the end of the light dependent reactions in photosynthesis. Regardless of where the enzyme is found, the purpose remains the same; create useable energy in the form of ATP. In cellular respiration, the ATP can be used for several different objectives.
Pathway: The Adenosine triphosphate / Creatine Phosphate Energy pathway: It is the energy pathway that provides anaerobic source of phosphate bond energy. The energy librated from splitting of CP rebounds ADP and Pi to form ATP. ATP is the energy source for all human movement. The release of one phosphate molecule provides the energy for the human movement. CP is the hi-energy
During the first one or two minutes of exercise, before the heart has pumped enough oxygenated blood to the working muscles, the muscles are powered by anaerobic energy. In order for these muscles to continue exercise, the body must supply them with continuous supply of oxygen, the more efficiently this is done, the better the cardiovascular fitness level. During cardiovascular conditioning, a program such as interva...
These results make sense because the heart beats faster in order to keep the body’s cells well equipped with oxygen. For one to continue exercising for long amounts of time, cells need to create ATP in order to use energy. Oxygen must be present for the process of creating ATP, which not only explains why higher respiratory rates occur during exercise but also faster heart rates. When the heart is beating rapidly, it is distributes oxygenated blood as fast as the body n...
If cells are denied energy, they will die. The second law of thermal dynamics says energy is lost in the form of heat whenever energy changes form. ATP is stored in the c. Glucose produced by C02, water and ATP. Respiration may be said to be a controlled breakdown of glucose that produces ATP for cell activities to be carried out. The purpose of the lab was to show the effect of temperature on the rate of respiration.
Aerobic requires oxygen and takes place inside the mitochondria of iving cells. The energy is stored as adenosine triphosphate (ATP) Aerobic respiration produces 2890KJ/Mole or 38ATP. This is much more than anaerobic. The
Aerobic exercise involves improving the cardiovascular system. It increases the efficiency with which the body is able to utilize oxygen (Dintiman, Stone, Pennington, & Davis, 1984). In other words, aerobic exercise means that continuous and large amounts of oxygen are needed to get in order to generate the amount of energy needed to complete the workout. The most common type of aerobic exercise is long-distance running, or jogging. While running, the body requires large amounts of energy in order for the body to sustain energy. “During prolonged exercise, most of the energy is aerobic, derived from the oxidation of carbohydrates and fats” (Getchell, 1976).
Why do we need to rely on renewable sources? Most of the energy that we use today come from fossil fuels such as natural gas, coal, and oil. All of these resources are non-renewable, it can finish one day. In order to have a better world and a healthy environment for the future, people are trying to obtain energy from natural resources instead of non-renewable sources. In the lecture “Renewable energy resources” (2014), Mistry focuses on some advantages and disadvantages of renewable energy. There are different kind of resources that we can use in order to produce renewable energy. Solar power, wind power, hydroelectric power are just some of the kinds of renewable energy that might be the best options to obtain energy because they come from
