The rate at which the body converts food to energy.
The chemical process in which food is broken down into useful forms to be used by the body.
the sum of all chemical processes taking place in our cells, and the rate at which these proceed Humans as organisms
Metabolism refers to the series of chemical changes that occur in an organism, by which means of which food is manufactured and utilized and waste materials are eliminated. Metabolism also refers to the rate at which your body burns calories to sustain life.
The chemical and physical processes that occur to maintain the body and produce energy.
The sum total of all chemical processes in the body that result in growth, energy, waste elimination and other body functions following food digestion and the distribution of nutrients in the blood.
The biochemical processes that sustain a living cell or organism.
The sum of the biochemical processes involved in the maintenance of life.
The process of cells burning food to produce energy. This is similar to a car's engine burning gasoline to produce the energy that is used to rotate the car's wheels. The cell's mitochondria acts as the car's engine, the food we eat acts as the gasoline, and the energy we need to move and think is similar to the energy used to move the car. Also referred to as energy metabolism.
the sum of the chemical and physical changes occurring in tissue.
Physical and chemical processes that sustain a living organism by producing, storing, and using energy.
A sequence of biochemical reactions in living organisms that converts food into energy used to drive other biological processes. Also, the sequence of transformations foreign compounds undergo inside a living cell.
Physical and chemical processes by which food is transformed into energy and tissues are broken down into waste products. It is a two-part process: One part is called catabolism -- when the body uses food for energy. The other is called anabolism -- when the body uses food to build or mend cells.
The sum total of all of the chemical reactions involved in living organisms. Refers to the body processes involved in digesting, absorbing, and excreting human nutrients and in supplying energy for the growth and development of cells.
the physical and chemical changes that nutrients undergo after their absorption from the gastrointestinal tract; the use of simple sugars, amino acids, and glycerol by the body cells.
The rate at which the body turns food into energy.
The sum of all physical and chemical changes that take place within the body. It involves anabolism ("building up" processes) and catabolism ("tearing down" processes). All metabolic processes are driven by energy derived from the major nutrients in food.
Metabolism (from Greek μεταβολισμός "metabolismos") is the biochemical modification of chemical compounds in living organisms and cells. It is through the process of metabolism that organisms process nutrients into the biochemical tools and structures they need to maintain a living state. Metabolism has two distinct divisions: anabolism, in which a cell uses energy and reducing power to construct complex molecules and perform other life functions such as creating cellular structure; and catabolism, in which a cell breaks down complex molecules to yield energy and reducing power.
