Metabolism.
metabolism
The process by which individual nutrients are used by cells in the body is called metabolism. Metabolism encompasses the chemical reactions that break down nutrients for energy or convert them into substances needed for cellular function.
Nutrients are needed by body cells.
The process by which nutrients and oxygen are oxidized in cells is cellular respiration. It involves the oxidation of nutrients usually by oxygen.
The movement of nutrients within cells is called intracellular transport. This process involves the movement of molecules and substances within the cell to where they are needed for cellular functions.
Cells take in nutrients through a process called endocytosis, where the cell membrane surrounds and engulfs the nutrients. Once inside the cell, the nutrients are broken down and used to support the cell's functions and growth.
Think of nutrients as fuel and building materials. They are necessary for a process called metabolism, which means building up and tearing down.
Bone cells receive their food and oxygen through blood vessels that supply nutrients to the bones. These blood vessels deliver nutrients and oxygen to the bone cells through a process called vascularization.
Nutrients enter the body through a process called absorption, where they are taken in by the cells for energy and other functions. Waste leaves the body through a process called excretion, where it is removed from the body to maintain a healthy internal environment.
Cellular metabolism is the process by which the body's cells are nourished and energized through the breakdown of nutrients and production of energy. This process involves various biochemical reactions that allow cells to function and carry out their basic functions.
The release of energy inside cells is called cellular respiration. It is a process that converts nutrients into adenosine triphosphate (ATP), the cell's primary energy source.
The process of respiration that uses oxygen is called aerobic respiration. During aerobic respiration, cells use oxygen to break down glucose and other nutrients to produce energy in the form of ATP. This process takes place in the mitochondria of cells.
