Section 4-1 ATP Section 4-1 ATP Write everything that is BLACK
4.1 Chemical Energy and ATP 4.1 KEY CONCEPT: All cells need chemical energy.
4.1 Chemical Energy and ATP The chemical energy used for most cell processes is carried out by ATP (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 food molecules to cell functions.ATP transfers energy from the breakdown of food molecules to cell functions. –Energy is released when a phosphate group is removed. –ADP is changed into ATP when a phosphate group is added.
4.1 Chemical Energy and ATP Organisms break down carbon-based molecules to produce ATP Carbohydrates are the most commonly broken down to make ATPCarbohydrates are the most commonly broken down to make ATP –not stored in large amounts –up to 36 ATP from one glucose molecule triphosphateadenosine diphosphate tri=3 di=2
4.1 Chemical Energy and ATP Fats store the most energyFats store the most energy –80 percent of the energy in your body –about 146 ATP from a triglyceride Proteins are least likely to be broken down to make ATP.Proteins are least likely to be broken down to make ATP. –amino acids not usually needed for energy –about the same amount of energy as a carbohydrate
4.1 Chemical Energy and ATP Chapter 4 Booklet 1.You are going to get 2 pieces of paper and fold them in half like a book! 2.The front page is the title page! Write on this page CELLS & ENERGY. Come up with some type of picture for the title page. 3.Open the book up and number the pages 1-7. 4.We will staple the spine to keep it all together.
4.1 Chemical Energy and ATP Page 1 & 2 1.Page 1: Title: ATP (write down the following then transfer on to your booklet on page one.) -Define ATP -Define ADP -How are ATP & ADP alike? -How are they different? 2.Page 2: Title: ATP & ADP -Draw, Label, & COLOR Figure 4.2 on page 101
