The process that occurs when an organism's body uses nutrients it takes in is called metabolism. Metabolism encompasses all the biochemical reactions that convert food into energy and building blocks for growth, repair, and maintenance of body tissues. It includes catabolic reactions, which break down nutrients to release energy, and anabolic reactions, which use that energy to synthesize necessary compounds. This overall process is essential for sustaining life and supporting various physiological functions.
Engestion is the process of taking in or consuming food or nutrients. It involves the ingestion of food, breakdown of nutrients in the digestive system, absorption of nutrients into the bloodstream, and elimination of waste products. The process is essential for providing the body with energy and essential nutrients for growth and maintenance.
Cellular respiration takes place in all cells. However, aerobic cellular respiration does not take place in all cells. Many cells undergo anaerobic cellular respiration.
Both Aerobic and Anaerobic cell respiration occurs in the Mitochondria.
Transcription occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. In eukaryotic cells, the process takes place in the nucleus where the DNA is located, while in prokaryotic cells, transcription occurs in the cytoplasm where the genetic material is found.
The part of the plant that conducts water and mineral salts to the leaves is called the xylem. Xylem vessels transport these essential nutrients from the roots upward through the stem to the leaves, where photosynthesis occurs. This process is crucial for maintaining the plant's hydration and nutrient supply.

Absorption is the process that takes nutrients through the small intestine wall. These nutrients then enter the circulatory system, which carries the nutrients to all body cells.
The longest part of the digestive process occurs in the small intestine. This organ takes several hours to digest food and absorb nutrients, as it is where most digestion and absorption of nutrients takes place. The small intestine's complex structure, with its villi and microvilli, maximizes nutrient absorption, contributing to the extended time required for this stage of digestion.
It is a process by which diffusible nutrients transfered from the gut into the blood or lymph by physico-chemical process and active transport. No absorption occurs in buccal cavity and very little absorption takes place in the stomach e.g. of alcohol. Particullarly all absorption takes place through the small intestine.
Cellular Respiration.
Active transport in plants occurs mainly in the root cells, where the uptake of essential nutrients from the soil takes place. This process requires energy to move molecules against their concentration gradient, ensuring that plants can absorb the necessary nutrients for growth and development.
process of re-uptake takes place
Assimilation in the human body primarily occurs in the small intestine. Nutrients from food are broken down and absorbed through the intestinal wall into the bloodstream, where they are transported to cells for energy, growth, and repair. The process of assimilation involves converting nutrients into forms that can be used by the body for various functions.
most of it takes place in the small intestines
The circulatory system picks up nutrients from the digestive system and takes them to the cells. Absorption is the process of moving the nutrients from the digestive system to the circulatory system.
Oxidation occurs in various parts of the body, primarily in the mitochondria where cellular respiration takes place. During this process, nutrients are oxidized to produce energy in the form of ATP. Oxidation also occurs in the cytoplasm during metabolic reactions that involve the breakdown of molecules for energy production.
Digestion is the biological process through which food is broken down into smaller, absorbable components, such as nutrients and energy. This process begins in the mouth, where mechanical and chemical breakdown occurs, and continues in the stomach and small intestine, where enzymes and acids further decompose food. Absorption of nutrients primarily takes place in the small intestine, while waste is eventually eliminated through the large intestine.
