Energy plays a crucial role in the body, as it is required for all of the body's functions and processes. The body uses energy to perform physical activities, such as exercise and movement, as well as to carry out all of its metabolic processes, such as digestion and the synthesis of hormones and enzymes.
The body obtains energy from the food we eat, which is converted into a form of energy called ATP (adenosine triphosphate). ATP is produced through the process of cellular respiration, which occurs in the mitochondria of cells. This process involves the breakdown of glucose and other nutrients to release energy.
In addition to ATP, the body also uses other forms of energy, such as the energy stored in fat cells. When the body is at rest or performing low-intensity activities, it primarily relies on fat stores for energy. However, during high-intensity activities, such as exercise, the body needs to access energy more quickly, and thus relies on ATP as its primary energy source.
The body has several systems in place to regulate energy production and utilization. For example, the endocrine system produces hormones, such as insulin and cortisol, which help to regulate the metabolism and use of energy in the body. The nervous system also plays a role in energy regulation, as it controls the body's response to physical activity and stress.
Overall, energy is essential for the body to function properly. It is required for physical activity and all of the body's metabolic processes, and is regulated by various systems in the body. Ensuring that the body has a sufficient supply of energy is important for maintaining good health and well-being.

Evidence submitted for assessment has been authenticated and accompanied by a signed and dated declaration of authenticity by the learner. The cardiovascular system transports simple molecules and materials to the liver and the body cells via the blood stream. Trillions of cells are found in the human body. It serves two fundamental purposes in living organisms: first is the removal of the electrons generated during catabolism and second, is generation of ATP adenosine triphosphate. Cellular respiration is an example of an catabolic reaction as it is the breakdown of larger molecules to Mooresville smaller ones. Common forms of energy in our world include heat, light, electrical energy, sound, mechanical energy, and chemical energy. This process normally uses heat but it can be done with other forms of energy as well such as light and electrical.

Cellular respiration takes place mainly in the mitochondria and the reactants in this process are oxygen and glucose and the main product in this process is ATP as well as waste products which include carbon dioxide and water. . Obesity results from an imbalance between foodintake and energy expenditure, which leads to an excessive accumulation of adipose tissue. Alcoholic fermentation is identical to glycolysis except for the final step. BMI is calculated by your weight and heights squared then multiply by 703. Biochemistry Sample Questions 944 Words 4 Pages How are these electron carriers reoxidized in anaerobic bacteria? Energy Homeostasis and Obesity Terrencia Rucker Saint Leo University Fried this, sugar that! As warm blooded people we can only digest food and function if our bodies are at a certain temperature and have enough energy, and energy is required for this. Human muscles will not be able to function as they are energy-less, preventing them from performing simple everyday tasks Moonie, 2010.
