AP Biology Reading Guide Fred and Theresa Holtzclaw Chapter 8: An Introduction to Metabolism Name_______________________Period___________ Chapter 8: An Introduction to Metabolism Concept 8.1 An organism’s metabolism transforms matter and energy‚ subject to the laws of thermodynamics 1. Define metabolism. 2. There are two types of reactions in metabolic pathways: anabolic and catabolic. a. Which reactions release energy? b. Which reactions consume energy? c. Which reactions build up larger molecules

Understanding the functions of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates

physiology of two named body systems in relation to energy metabolism in the body. (P4) In this assignment I will be explaining the physiology of two named body systems in relation to energy metabolism in the body‚ the Respiration system and the Digestive system. I will start off by giving a definition of energy metabolism in the body. Metabolism in the body is a collection of chemical reactions that takes place in the body’s cells. Metabolism converts the nutrients in the food that we eat in to essential

Study of Oxygen Consumption to Measure Energy Metabolism in Mammals Brianne Simonsen Lab Section 8 4 Oct. 2005 Abstract In this experiment the oxygen consumption of a mouse in environments of varying temperatures was studied. The hypothesis behind this experiment was that more oxygen would be consumed at a lower temperature to maintain body heat. To measure the rate of oxygen consumption a mouse was given a specific amount of oxygen. The amount consumed in a specific time was measured and

Analyse how the cardiovascular and the digestive system interrelate to perform energy metabolism. Energy is used up all the time for body processes. Energy starts at conception and continues to carry on until you die. The amount of energy you need depends upon your age‚ sex and your level of activity. Food provides the energy we use; our foods bring us the vital energy that our body is burning throughout the day. Body growth‚ development and functioning are some of the vital and fundamental aspects

of energy for metabolism. With all this energy trapped inside‚ how can the candy bar sit still on the shelf in the grocery store? Indeed‚ candy bars have a significant amount of carbohydrates (mostly simple‚ such as sugar) in their composition. The energy stored within these carbohydrates is chemical potential energy‚ and cannot actually be released or converted into usable chemical energy until it is eaten and taken up into the body‚ where various cells break down the carbohydrate molecules and

cardiovascular‚ respiratory and digestive systems which supply energy to the cells of the body. I will be describing their role of energy in the body system also I am going to explain the physiology of the three named body systems in relation to energy metabolism. Respiratory System The respiratory system consists of tissues and organs in your body which are formed into groups. The system includes airways‚ lungs‚ blood vessels and muscles attached to work together so an individual can breathe. The respiratory
