Section 4-1 Section 4-1 “ATP “ATP ” ” Write everything that is Write everything that is BLACK BLACK 4.1 Chemical Energy and ATP 4.1 KEY CONCEPT: 4.1 KEY CONCEPT: All cells need chemical energy. All cells need chemical energy. 4.1 Chemical Energy and ATP The chemical energy used for most cell The chemical energy used for most cell processes is carried out by ATP processes is carried out by ATP (adenosine triphopshate) (adenosine triphopshate) Starch molecule Glucose molecule • Molecules in food store chemical energy in their bonds. Molecules in food store chemical energy in their bonds. 4.1 Chemical Energy and ATP phosphate removed • ATP transfers energy from the breakdown of ATP transfers energy from the breakdown of food molecules to cell functions. food molecules to cell functions. – Energy is released when a phosphate group Energy is released when a phosphate group is removed. is removed. – ADP is changed into ATP when a phosphate ADP is changed into ATP when a phosphate group is added. group is added. 4.1 Chemical Energy and ATP Organisms break down carbon-based Organisms break down carbon-based molecules to produce ATP molecules to produce ATP • Carbohydrates Carbohydrates are the most commonly are the most commonly broken down to make ATP broken down to make ATP – not stored in not stored in large amounts large amounts – up to 36 ATP up to 36 ATP from one from one glucose glucose molecule molecule triphosphateadenosine adenosine diphosphate tri=3 di=2 4.1 Chemical Energy and ATP • Fats Fats store the most energy store the most energy – 80 percent of the energy in your body 80 percent of the energy in your body – about 146 ATP from a triglyceride about 146 ATP from a triglyceride • Proteins Proteins are least likely to be broken are least likely to be broken down to make ATP. down to make ATP. – amino acids not usually needed for energy amino acids not usually needed for energy – about the same amount of energy as a about the same amount of energy as a carbohydrate carbohydrate 4.1 Chemical Energy and ATP Chapter 4 Booklet Chapter 4 Booklet 1. 1.
