Chapter 7 Notes- Metabolism Chemical Reactions in the Body 1. Plants use the sun’s energy to make carbohydrate from CO 2 and H 2 O. 2. This is called photosynthesis. 3. Humans and animal eat the plants and use the carb as fuel for their bodies. 4. During digestion, the energy-yielding nutrients are broken down to monosaccharides, fatty acids, glycerol, and amino acids. 5. After absorption, enzymes and co-enzymes can build more complex compounds. 6. In metabolism, they are broken own further into energy (ATP), water and carbon dioxide. 1. Metabolic reactions take place inside of cells, especially liver cells. 2. Anabolism is the building up of body compounds and requires energy. 3. Catabolism is the breakdown of body compounds and releases energy. 1. The Transfer of Energy in Reactions- ATP a. A high-energy compound called adenosine triphosphate (ATP) is made. b. Coupled reactions are 2. Enzymes and coenzymes are helpers in reactions. a. Enzymes are protein catalysts that cause chemical reactions. b. Coenzymes are organic molecules that function as enzyme helpers. c. Cofactors are organic or inorganic substances that facilitate enzyme action. 1. The breakdown of glucose to energy starts with glycolysis to pyruvate.
