Metabolic Rate Calculator

A basal metabolic rate calculator is not an object as much as an equation or method used to determine one's basal metabolic rate, or the rate at which the body burns calories while sleeping.  There are two main equation systems used for calculating basal metabolic rate, which can be extremely helpful in determining a diet or exercise plan, especially those devoted to either weight loss or optimizing physical fitness. 

Cell Metabolism

Cell metabolism is the name generally given to the variety of metabolic functions that are completed within a cell.  In some ways, cellular metabolism should simply be a synonym for metabolism, and nearly all human metabolism is performed at a cellular level.  Proper cell metabolism functions as a means by which tissues are created an repaired, and by which energy is provided and transported for use throughout the body.

Slow Metabolism

Slow metabolism can result from a variety of causes and conditions.  The term can refer in medical parlance to the body's  below average rate at performing necessary metabolic functions, but in many instances it is used in reference to weight loss.  Metabolic weight loss is easier for some people than others, and those with slower than average metabolism often have to overcompensate significantly to achieve it. 

Glucose Metabolism

Glucose metabolism can refer to many different metabolic functions that relate to glucose.  In one respect, it can refer to complex breakdown of glucose in cellular respiration to generate energy and transport molecules.

Metabolism of Fat


Fatty acid metabolism is one of the most important sources of energy for the body, and is a vital part of maintaining human function.  It can really be used to describe a few different metabolic function: such as fat's metabolism in fatty acids, or the construction of vital tissues and compound from fatty acid, and the creation of energy from the breakdown of triglycerides.

Metabolic Maintenance

There are many ways in which one can maintain and even improve metabolism.  For the large part, metabolic maintenance is best accomplished though consistent exercise, which keeps the amount of energy produced by the body consistent, and maintenance of a balanced diet that does not take in more calories than the body can metabolize.  Hormone treatments, too, can be used for maintaining health metabolic function.

Bilirubin Metabolism

Bilirubin metabolism refers to the various functions that produce and regulate the compound bilirubin.  Bilirubin is something of waste product, but one that requires further metabolic reactions before in can be excreted from the body as waste.  This can be done in a number of forms and fashions, all of which are dependent on where in the body the bilirubin is produced. 

Aerobic Metabolism


Aerobic metabolism is the function by which cellular respiration is performed utilizing oxygen as its primary source of combustion.  Cellular respiration is the process by which glucose is broken down through metabolic functions into usable energy, energy transport molecules, and waster products water and carbon dioxide.  Aerobic metabolism is often accelerated during periods of semi-intense cardiovascular exercise. 

Amino Acid Metabolism

Amino acid metabolism is a blanket term that can be used to describe the many vital metabolic functions that involve amino acids. Amino acids are the most crucial building blocks of organic life, and play a role in every major form of metabolism.  It may specifically refer to protein synthesis, the creation of proteins from amino acids, or amino acid synthesis, where amino acids are created from breaking down proteins.

Anaerobic Metabolism

Anaerobic metabolism occurs when cellular respiration, the conversion of glucose into usable energy, is performed in cells using something other than oxygen for combustion.  In humans, it generally occurs during periods of intense physical stress or exercise.  Cell fermentation is similar to anaerobic metabolism, as it also does not require oxygen, but only completes the first portion of cell respiration, with its byproducts broken down into waste.

Metabolic Bone Disease

A metabolic bone disease is one of many different conditions where an impairment or imbalance in metabolic function causes abnormalities in a patient's bone.  These diseases can be caused by deficiencies in substances such as calcium and vitamin D, or due to genetic metabolic disorders that lead to weakened bones.  Examples include Paget's disease of the bone, and rickets. 

First Pass Metabolism

First pass metabolism is a phenomenon that occurs to certain pharmaceuticals after they have been ingested by the body.  When the first-pass effect occurs, a medication absorbed through the digestive tract, instead of being circulated throughout the body is instead almost entirely metabolized in the liver.  This process allows so little medication to enter the blood that it becomes essentially useless. 

Glycogen Metabolism

Glycogen metabolism refers to two specific metabolic functions: either the breakdown or formation of glycogen.  Glycogen is a complex molecule created from glucose by the body to be used at a later time.  When blood sugar is low, glycogen is metabolically broken down into usable glucose to provide energy for the body. During high blood sugar, the excess glucose is converted to glycogen and stored in the muscles and liver.

Catabolism

Catabolism is one the two main classifications of metabolic function, in which molecules are broken down into either smaller, less complex molecules, or energy.  Catabolic reactions are among the most vital to establishing a stable body metabolism, as cellular respiration and amino acid synthesis, two of the main metabolic functions, are kinds of catabolism.
