Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine. The body needs lots of haemoglobin because it will combine with the gases; oxygen and carbon dioxide. The red cells carry the oxygen in the arteries and capillaries to cells of the body. One function of the blood is to transport materials within plasma and hemoglobin around the body. Plasma contains hormones, nutrients and waste substances.
This happens inside of the mitochondria. • What is the role of the electron transport system? Include the reactants and the products. Where does it occur? The role of the of the electron transport system is to turn the electrons given off from the other two processes and turn them into ATP.
P4- Explain the Physiology of two named body systems in relation to energy metabolism in the body. In this essay I am going to be explaining how energy is made in the body and two body systems that help to produce this energy. “The metabolic systems are responsible for the chemical reactions within the body. These reactions are involved in the maintenance of the living organism and may be involved in reactions that break compounds down catabolic reactions or reactions which build compounds up anabolic reactions”. (King R 2012) They all require energy to work.
M1: Discuss the role of energy in the body The best way to describe energy is to describe what it does. Energy is the ability to do work or cause movement. Common forms of energy in our world include heat, light, electrical energy, sound, mechanical energy, and chemical energy. Most metabolic processes in the body use chemical energy, which is held in the bonds between the atoms of molecules and is released when these bonds are broken. “The muscles are no different.
The cart causes the supporting structure to flex, bend and vibrate and producing kinetic energy but not on the cart but on the track. The conservation of energy illustrates work and energy relationships. It states that the work done by external forces changes the amount of mechanical energy. Energy cannot be created or destroyed and it remains constant. The conservation of energy in the case of a roller coaster demonstrates that when a cart reaches its initial summit only force is gravity.
Energy is the capacity of a physical system to perform work. Energy exists in several forms such as chemical, electrical, heat, sound, light and mechanical. http://physics.about.com/od/glossary/g/energy.htm Energy can be defined in a variety of different ways. However, the most common way to define energy is ‘the ability to work’. All living organisms need energy to survive, all the basic functions of a human to survive need energy, to maintain them from not stopping.

P4: Explain the physiology of two named body systems in relation to energy metabolism in the body. M1: Discuss the role of energy in the body. Energy laws Energy can be defined as the capacy to do work.
This process is fractional distillation. c) Some properties of hydrocarbons depend on the size of their molecules. These properties influence how hydrocarbons are used as fuels. boiling points viscosity flammability. C1.4.3 Hydrocarbon fuels Additional guidance: a) Most fuels, including coal, contain carbon and/or hydrogen and may also contain some sulfur.
The sum of all chemical reactions in the body is? Metabolism 27. Polysaccharide that serves as a storage form of energy in muscle and liver cells? Glycogen 28. Two organ systems that regulate and maintain homeostasis are the Nervous and endocrine systems 29.
* An electrogenic pump is a transport protein that generates voltage across a membrane * Animal- sodium/potassium * Plants- proton pump Understand how a co-transporter works. Where you likely find one? Understand how large molecules and particles are transported across membranes including the role of Vesicles. What is meant by endocytosis? There are several types – what are they and how do they differ?
