The liver is the most metabolically active organ in the body. After nutrients have been absorbed, the liver determines the metabolic fate of these nutrients. Metabolic processes in the liver convert amino acids, monosaccharides, glycerol, and fatty acids to usable or storable forms of energy.
Where does metabolism occur in the body?
The liver is the primary site for metabolism. Liver contains the necessary enzymes for metabolism of drugs and other xenobiotics.
What is metabolism quizlet?
Define metabolism. Metabolism refers to the chemical reactions in the body that build and breakdown molecules. Describe an example of metabolism. Cells need energy to function. If a person is eating something that has sugar, the sugar molecules get broken down into simpler molecules and that releases energy.
What has the greatest effect on metabolism?
Don’t be too quick to blame a ‘slow metabolism’ for weight gain as better food choices and exercise have the biggest impact. The biggest component of your metabolism, (50-80%) of the energy used, is your basal metabolic rate (BMR), which is the energy your body burns just to maintain functioning at rest.
Which of the following is a anabolic pathway that synthesizes glycogen?
In these tissues it is stored as glycogen, a highly branched macromolecule consisting of thousands of glucose monomers held together by chemical bonds. The glucose monomers are joined together by an anabolic pathway called glycogenesis. For each molecule of glucose stored, one molecule of ATP is used.
What is metabolism rate of human body?
An average man has a BMR of around 7,100 kJ per day, while an average woman has a BMR of around 5,900 kJ per day. Energy expenditure is continuous, but the rate varies throughout the day. The rate of energy expenditure is usually lowest in the early morning.
What is metabolism in the human body?
Metabolism is a term that is used to describe all chemical reactions involved in maintaining the living state of the cells and the organism. Metabolism can be conveniently divided into two categories: Catabolism – the breakdown of molecules to obtain energy.
What is metabolism process?
Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. … Specific proteins in the body control the chemical reactions of metabolism. Thousands of metabolic reactions happen at the same time — all regulated by the body — to keep our cells healthy and working.
What is metabolism example?
An example of a metabolic reaction is the one that takes place when a person eats a spoonful of sugar. … Once inside the body, sugar molecules are broken down into simpler molecules with the release of energy.
What is metabolism health quizlet?
Metabolism is the sum of the processes by which a particular substance is handled in the living body. Metabolism is the sum of all anabolic and catabolic cellular reactions. You just studied 288 terms!

When glycogen is broken down into glucose The process is called?
Glycogenolysis is the biochemical pathway in which glycogen breaks down into glucose-1-phosphate and glycogen. The reaction takes place in the hepatocytes and the myocytes. The process is under the regulation of two key enzymes: phosphorylase kinase and glycogen phosphorylase.
Where does Glycogenesis occur in the body?
Glycogenesis, the formation of glycogen, the primary carbohydrate stored in the liver and muscle cells of animals, from glucose. Glycogenesis takes place when blood glucose levels are sufficiently high to allow excess glucose to be stored in liver and muscle cells.
How is glycogen broken down in muscle?
The Cori cycle states that skeletal muscles glycogen is broken down during adrenaline stimulation and released as lactate, and converted to glucose in the liver.
