Document Summary
Nutrients from ingested foods are provided and stored as carbohydrates fats and proteins: theses 3 fuels (cid:862)su(cid:271)strates(cid:863) (cid:272)an (cid:271)e (cid:271)roken down in the (cid:272)ells to release stored energy. Bioenergetics: chemical pathways in cells, convert substrates to energy. Metabolism: all the chemical reactions in the body. The process of producing energy (atp) in a biological system and using atp to do work: ex. Power myosin-actin bridge cycling, power many enzymes and ion pumps. Types include thermal, chemical, mechanical, electrical, radiant and atomic/nuclear: energy reactions: energy releasing reactions, endergonic reactions: energy-consuming reactions. Total of all the catabolic (break down) /exergonic and anabolic (build up) /endergonic reactions in a system. Catabolic: breakdown of larger molecules into smaller molecules. Anabolic: synthesis of larger molecules form smaller molecules. Atp is the metabolic currency in biological tissues. Atp consists of three phosphate groups, ribose and adenine.
