2 types of metabolic reactions. Have you ever known someone who can eat tons of food but never gains any weight? Anatomy and Physiology, Chapter 4, Cell Metabolism.
All metabolic reactions occur in steps, in which compounds are gradually built up or broken down. Published by Houghton Mifflin Company.The American Heritage® Science Dictionary Anabolism Definition Anabolism or biosynthesis is the set of biochemical reactions that construct molecules from smaller components. Overview of metabolism Cells are constantly carrying out thousands of chemical reactions needed to keep the cell, and your body as a whole, alive and healthy. These include processes that break down substances to yield energy and processes that build up other substances necessary for life.Sum of chemical and physical changes occurring in tissue, consisting of anabolism (those reactions that convert small molecules into large), and catabolism (those reactions that convert large molecules into small), including both endogenous large molecules and biodegradation of xenobiotics. Copyright © 2002, 2001, 1995 by Houghton Mifflin Company. metabolism the sum total of the chemical processes occurring in cells by which energy is stored in molecules (ANABOLISM) or released from molecules (CATABOLISM), life being maintained by a balance between the rates of catabolic and anabolic processes.
Metabolism (/ məˈtæbəlɪzəm /, from Greek: μεταβολή metabolē, "change") is the set of life -sustaining chemical reactions in organisms. These chemical reactions are often linked together in chains, or pathways.
Metabolism consists of anabolism (the buildup of substances) and catabolism (the breakdown of substances). Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012The American Heritage® Stedman's Medical Dictionary a reaction that breaks down larger molecules to release energy.

Based on the Random House Unabridged Dictionary, © Random House, Inc. 2020Collins English Dictionary - Complete & Unabridged 2012 Digital Edition Metabolismis defined as the sum of all of the chemical reactions within the human body. We often blame metabolism for these two phenomena.

Metabolism is the sum of all catabolic (break down) and anabolic (synthesis) reactions in the body. Anabolic reactions are endergonic , meaning they require an input of energy to progress and are not spontaneous.
Or, how about someone who tries to lose weight, yet cannot seem to drop the pounds? In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.The functioning of a specific substance, such as water, within the living body.The chemical processes by which cells produce the substances and energy needed to sustain life. [ mĭ-tăb ′ə-lĭz′əm ] The chemical processes by which cells produce the substances and energy needed to sustain life.

Published by Houghton Mifflin Harcourt Publishing Company. ncjp19. As part of metabolism, organic compounds are broken down to provide heat and energy in the process called catabolism. 22 Terms. All of the chemical reactions that take place inside of a cell are collectively called the cell’s metabolism.
The term metabolism is commonly used to refer specifically to the breakdown of food and its transformation into energy.
