Heart cells also store appreciable amounts of oxygen in myoglobin. Metabolism is a balancing act involving two kinds of activities that go on at the same time: building up body tissues and energy stores (called anabolism) breaking down body tissues and energy stores to get more fuel for body functions (called catabolism) Anabolism (pronounced: uh-NAB-uh-liz-um), or constructive metabolism, is all about building and storing. Gastrointestinal tract, pathway by which food enters the body and solid wastes are expelled. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.
