Compare And Contrast The Three Energy Systems

Energy is defined as the capacity for vigorous activity, and to ensure a continuous and sufficient supply of energy for all daily activities, there are three energy systems that work together. These systems are the ATP-PC system, the anaerobic glycolytic system and the aerobic system. Each system produces a different chemical energy from different sources at different speeds. Both the ATP-CP system and anaerobic glycolytic systems are anaerobic systems, meaning oxygen is not used to synthesise ATP. As a result, these systems produce energy quicker however they do not last very long. Comparatively, the aerobic system heavily relies on oxygen to synthesise ATP. As the chemical process uses oxygen to produce energy, it is more complex than the anaerobic processes. The aerobic system takes longer to produce energy

The initial burst of speed and subsequent 5 seconds in the 100m sprint, is fuelled by the Phosphagen ATP- PC system as there is 4-5 times more Phosphocreatine (PCr) readily available in the skeletal muscles compared to that of ATP (1). The initial ATP stored is used within 2 seconds of maximal activity by the Myosin ATPase enzyme to cleave energy, leaving Adenosine Diphosphate (ADP)

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

In this task I will be examining how the different body systems use energy and why the body needs energy. I will also be analysing cellular respiration which is the process in which energy is made, along with the by-products and anabolism and catabolism. Later on in this task I will be analysing how ATP is used in muscle action, protein production and how we as mammals use the energy released as heat.

As stated before the three energy systems used by the body are the ATP-PC, anaerobic glycolysis and aerobic system. The ATP-PC and anaerobic glycolysis system (also known as lactic acid system) are anaerobicly based meaning that they don’t need a sufficient amount of oxygen to produce ATP. The aerobic system requires oxygen to produce ATP hence its name. All three system have fuels’ which produce energy. The ATP-PC uses phoso creatine and creatine phosphate, the lactic acid system uses glycogen and the aerobic system uses glycogen and triglycerides . Glycolysis refers to the breaking down of glycogen to from glucose which is used in ATP.

The energy for all physical activity comes from the conversion of high-energy phosphates (adenosine triphosphate—ATP) to

Your body requires energy in order to be able to perform tasks. Energy comes in many different forms. They are chemical, light, sound, heat and mechanical. You can get energy from different food substances i.e. glucose, fatty acids, sugars and amino acids. To be able to get the energy from these food substances energy needs to be released with oxygen. This is known as aerobic respiration. The role that energy plays in our body is the process of moving molecules in and out of our cells while breaking down the larger molecules and building new molecules. The cardiovascular system transports oxygenated blood around the body and to the cells. It will then collect the deoxygenated blood which is ready for the excretion from the cells. The cardiovascular system will deliver the nutrients oxygen and glucose via the blood stream. Oxygen is need for aerobic respiration to occur. The cardiovascular system will pump oxygen and nutrients carrying blood throughout the body. The glucose molecules that are carried by the blood are transported into the cells. Along with the oxygen that is diffused into the cells they are used in respiration to produce ATP. The respiratory system is responsible for bringing in oxygen as well as using it to burn the nutrients that we need for energy. The respiratory system contains alveoli which allow the diffusion of oxygen into the blood stream

Metabolism comprises of a vital set of biochemical reactions that all living organisms require to sustain life. For a marathon runner, their physiological response to strenuous exercise depletes both their fats and carbohydrate storage in order to supply energy in the form of Adenosine Triphosphate (ATP). ATP is the energy form that the human body uses for biological processes such as movement and synthesis of biomacromolecules. In regards to running a marathon, the athlete is capable of using a combination of both anaerobic and aerobic pathways, but these different systems predominate at different intervals in order to increase the energy allowed for the muscles.

Energy is stored within the bonds in the body that hold atoms and molecules all in one place, the cells can break down the glucose molecules, this is done through a chemical reaction. This can take place within the cytoplasm and it is then finished within the mitochondria, this is known as cellular respiration.

Our body produces energy called ATP. ATP is the renewable energy source for our cells that consists of 3 phosphates, a sugar and an adenine ring. ATP can be produced in two ways, through aerobic respiration or anaerobic respiration. Aerobic respiration occurs when there is oxygen, and anaerobic occurs when oxygen is not available. Also there are normally 3 phases in respiration, glycolysis, krebs cycle, and the electron transport chain. During glycolysis the glucose splits into two

There are three main energy systems in the human body: ATP-PC, glycolytic and oxidative. They can often overlap, but one will clearly dominate depending on need.

However, if intense physical demands such as cycling, swimming or running are placed on the body, the systems respond by producing much higher levels of ATP to ensure that our immediate energy needs are met. When doing these exercises ATP then becomes ADP, as there is a loss in the phosphate molecules. The body has two main energy systems, the aerobic energy system which utilises fats, carbohydrate and sometimes proteins for re-synthesising ATP for energy use.

Anaerobic is the main training for athletes in strength and endurance sports. The ATP-PC (adenosine triphosphate phosphocreatine) and the lactic acid systems are the two main energy chains comprised for these events.

All three of your energy systems ultimately run on ATP: It’s the fuel source for all your physical functions, from eating to breathing to running hill sprints. Your glycolytic and oxidative systems (which we’ll cover shortly) make most of this ATP to order, cobbling it together from the food you eat and the air you breathe as need arises.

An athlete needs to ensure that they consume enough fuel to complete activities undertaken. The amount of energy required depends on many factors including size and weight of the athlete, level and intensity of the training, and due to this the amount of energy required varies from person to person. However if more energy is consumed than required, the excess is stored as fat and weight will increase, on the other hand if insufficient energy is consumed the body calls upon its stores to meet the demand and weight will be lost.
