Ch. 5 Define metabolism and describe the fundamental difference between anabolism and catabolism -Metabolism is involved with the buildup and breakdown of macromolecules within a cell; these chemical reactions provide energy and create substances that sustain life -Catabolism: breaks down complex molecules; provides energy and building blocks for anabolism; EXERgonic -Anabolism: uses energy and building blocks to build complex molecules; ENDERgonic Ch. 5 Identify the role of ATP as an intermedi...

What is metabolism? Metabolism is all of the chemical reactions in an organism. What are the major classes of metabolic reaction? Catabolism: All of the decomposition reactions in an organism taken together. Anabolism: All of the synthesis reactions in an organism taken together. What is oxidation and recucition reaction? What does is comprise of? Any metabolic reaction involving the transfer of electrons from an electron donor to an electron acceptor. Reactions when electrons are accepted are...

I. Enzymes and coenzymes. Regulation of metabolism. 1. Enzymes: definition, structure and properties of enzymes. - Enzymes definition are biological catalysts, which determine the rate and pattern of chemical transformations in biological systems that underlie the meta- bolic pathways. According to their chemical nature, all the enzymes are pro- teins. Shortly speaking, enzymes are designated as biological catalysts of a protein nature. Under the catalytic action of enzymes biomolecules (s...
