Energy Metabolism: Cardiovascular and Digestive Systems

1. When we say that something gives us “energy,” what does that mean? What is a biological definition of energy?

Energy keeps all living organisms alive, as they need a continual supply of energy to function in order to survive. Some of these processes are continuous such as, metabolism, which is the chemical reactions which occur in the body, these occur by using or releasing energy from chemical substances. Another continuous process which use energy is the transporting of molecules in order for them to break down, and to build new ones. The breakdown of large molecules into their simpler forms to release energy is known as catabolism, for example, when glucose is used in a cell to release energy. And the opposite reaction, is called anabolism. This is when energy is used to build complex structures from simple cells, for example, tissue growth and

Explain the physiology the cardiovascular and the digestive system in the body in relation to energy metabolism in the body. Discuss the role of energy in the body and analyse how those two body systems interrelate to perform a named functions. For distinction analyse

Energy metabolism comes in different types such as Anabolism and Catabolism energy. They all make sure that energy breaks down

This report will discuss the work of the energy interplay system in relation to a subject’s result in the 20 metre beep test . Energy system interplay refers to the work done by the three energy systems (ATP-PC, Anaerobic and Aerobic) to provide the body with the necessary amount of adenosine triphosphate (ATP) to complete certain physical activities depending on their intensity and duration.

Explain what they are, their functions and where they are found. Then go into detail about two organs, with their functions, what tissues they are made of and where they are found in the body.

Energy metabolism is where the nutrients oxygen and glucose are took in and delivered the organs. Energy is needed in order for our body to be able to function. Energy helps break down molecules and to build new molecules.

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.

Energy is expended in a number of different ways such as the stated above; resting metabolic rate, thermic effect of activity, thermic effect of feeding and adaptive thermogenesis. An individual’s energy balance is the balance of calories consumed through eating and drinking compared to calories burned through physical activity, what an individual drinks and eat is energy in. what an individual burns though physical activity is energy out. Body weight is maintained and stable in the state of energy balance, the chemical bonds of carbohydrates, proteins and fats in food contain chemical energy which is then transformed in the human body in multiple metabolic processes to cellular energy, heat or stored energy. An individual’s burns a certain number of calories just by breathing air and digested food. They also burn a certain number of calories through their daily routine, an important part of maintaining energy balance is the amount of physical activity an

Introduction: Cellular respiration and fermentation are used in cells to generate ATP. All cells in a living organism require energy or ATP to perform cellular tasks (Urry, Lisa A., et al. , pg. 162). Since energy can not be created (The first law of thermodynamics) just transformed, the cell must get its energy from an outside source (Urry, Lisa A., et al. , pg.162). “Totality of an organism’s chemical reactions is called metabolism” (Urry, Lisa A., et al., pg. 142). Cells get this energy through metabolic pathways, or metabolism. As it says in Campbell biology, “Metabolic pathways that release stored energy by breaking down complex molecules are called catabolic pathways” (Urry, Lisa A., et al. pg.

These can include carbon dioxide and water as well as the breakdown from proteins which

All of these systems work together in the body in this essay I am going to write about the digestive system, cardiovascular system and the respiratory system and I'm going to write about how they work together in the human body.

All of the chemical processes of the cell are called metabolism. The breakdown or degradation of complex organic molecules to yield simple molecules and energy is called catabolism. Anabolism is the total biosynthetic processes where large complex molecules are made from small simple molecules. Anabolic processes require energy because order is being created and thus work must be done. Overall, both processes of metabolism must occur concurrently because catabolism provides the energy necessary for anabolism.

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.

“Metabolism is the set of chemical reactions that happen in living organisms to maintain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments” (Metabolism). Metabolism breaks down the food that we eat, transforming it into energy for our bodies. Metabolism is broken down into two categories Anabolism and Catabolism, which help aid in the chemical reaction process. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions (Dowshen). Metabolism is a constant process that begins when we're born and ends when we die. It is a vital process for all life not just humans, and
