Written by tutor John M. This cycle involves a series of reactions involving a 1 a substrate, Oxaloacetate, that is modified in every reaction, 2 Acetyl—CoA, from which energy is extracted, 3 energy transport reactants, which collect the extracted energy, and 4 the controlling enzymes, which regulate the steps of the cycle. This cycle is ubiquitous in living organisms, single and multi-celled, both plants and animals — including humans.
Metabolism is a term used to refer to the Metabolism outline of food and its subsequent transformation into energy the persons body needs. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments.
The word metabolism can also refer to all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells, in which case the set of reactions within the cells is called intermediary metabolism or intermediate metabolism.
Metabolism is something that consists of both,' Catabolism,' and, 'Anabolism;' which are the buildup and breakdown of substances. In the field of Biology, Metabolism refers to all of the body's chemical processes, the digestion of food, and the elimination of waste.
Every living cell in a person's body has a metabolism, referred to as, Cell Metabolism. Metabolism outline organisms such as animals and plants do as well.
People have an overall metabolism that differs from the metabolism of individual cells. There are metabolic pathways which form a two-part process; the first part is the one mentioned called, 'Catabolism,' during which the body processes food to use for energy.
The other part is called, 'Anabolism,' where the person's body uses food in order to either repair or build cells. The metabolic process ceases only when a person dies. The term, 'Catabolism,' comes from the Greek word, 'Cata,' which means, 'down. An example of this process is the digestion of protein which is then broken down into amino acids that a person's body can absorb and use through the metabolic process, storing glycogen in their liver for energy.
Chemically, this process is known as an, 'Oxidation Reaction. The term, 'Anabolism,' comes from the Greek word, 'Ana,' which means, 'up. An example of this is the assembly of amino acids into larger proteins and the subsequent synthesis of fat and glycogen for the person to use as energy.
Chemically, this synthetic process is known as a, 'Reduction Reaction. Chemical energy is something that is measured in calories, or the amount of energy that will heat one gram of water by one degree Celsius.
It is easier to measure calories by kilo-calories, or, 'kcal's'. One kcal is 1, calories; something that both food labels and Dietitians refer to as a calorie with a capital, 'C.
A person's metabolic rate is commonly expressed in terms of kcal's per hour or day. One way to measure someone's metabolic rate is through the use of a, 'Spirometer,' which is a device that measures their rate of oxygen consumption.
For every liter of oxygen a person breathes, they use about 4. A person's metabolic rate is dependent on certain variables such as whether or not they have been fasting, their hormone levels, physical activity, their mental state, and their thyroid hormone in particular.
A person's metabolic rate rises due to physical activity, anxiety, eating, pregnancy, fever or other factors. There are factors that can reduce a person's total metabolic rate as well, such as apathy, depression, or prolonged starvation.
Children have a higher TMR than adults. As people near middle-age they gain weight many times, even though they may not change their eating habits.
People who pursue diets can become frustrated in part because initial weight lost is from water that is rapidly regained, but also because their TMR declines over time.Fatty Acid Metabolism.

The major classes of inborn errors of metabolism (IEM) and their characteristic clinical and biochemical features are described below. The epidemiology, pathogenesis, clinical presentation, evaluation, and initial management of IEM are discussed separately, as are specific disorders.

Your Genes. Metabolism is how your body changes food into energy. If your body is slow at burning calories while you rest or sleep, you probably got that from your parents, through your genes.
Sydney dietitian and nutritionist Lyndi Cohen revealed the simple lifestyle tweak you can do to speed up your metabolism to help you lose weight.
Energy Metabolism. Facebook. Twitter. Linkedin. Pinterest. Google+. StumbleUpon. Utilization of energy involves the metabolism of carbohydrates and lipids. Normally, carbohydrate metabolism dominates, but in states of negative energy balance, lipid metabolism becomes dominant. Section outline. Lipid overview: Information on lipemia. Glucose Metabolism. Energy is required for the normal functioning of the organs in the body. Many tissues can also use fat or protein as an energy source but others, such as the brain and red blood cells, can only use glucose.
