Learning Targets 1. _______________________________________________________________________. 2. ________________________________________________________________________ _______________________________________________________________________. Preview What is ATP compared to? What process converts glucose into energy? a. Dehydration Synthesis b. Respiration c. Photosynthesis Describe ADP: a. High energy carrier, 2 phosphates b. Lower energy carrier, 2 phosphates c. Both are correct What are the three parts of an ATP molecule? Why is ATP able to remove a phosphate group so easily? When is energy released? a. When the bond is broken. b. When the water molecule is added. Note Taking Guide What is energy? What three things do living things depend on energy for? 1 What is Adenosine triphosphate used for? What is ATP made up of? How can cells store extra energy? How do cells release energy stored in ATP? ATP is used to carry out active transport. What is an example of active transport? Give two examples of how ATP powers movement. True / False. ATP is not needed to make proteins. True / False. The blink of a firefly on a summer night comes from an enzyme powered by ATP. What is the difference in heterotrophs and autotrophs? Which type of organism uses photosynthesis to convert the energy of sunlight to sugars that are used as food? 2 Study Adenosine triphosphate (ATP) is the energy molecule used by all cells to do work. It is a nucleotide consisting of a nitrogen-containing base (adenine, thymine, cytosine, or guanine), a 5-carbon sugar, and 3 phosphate groups. ATP is able to store and transport chemical energy within cells. The LAST TWO phosphate groups (PO4), are joined by HIGH-ENERGY bonds. When these bonds are broken, energy is released for cells to use and ADP forms. Enzymes help to break and reform these highenergy bonds. What does ATP stand for? What three main things make up an ATP molecule? How many high-energy bonds does ATP contain? Where are these high-energy bonds found in ATP? What helps weaken these bonds so energy can be released and then later help reform them? When ATP loses a phosphate group __________ is released for cells and a molecule of _________ forms. In the image below, COLOR the 5-carbon sugar RED and LABEL it RIBOSE. COLOR and LABEL the nitrogen-base DARK BLUE. COLOR and LABEL the 3 phosphate groups YELLOW, and COLOR & LABEL the 2 high-energy bonds GREEN. 3 Practice At the end of this packet you will find shapes and words representing each part of the ADP/ATP cycle. You will need to color the adenosine blue, the ribose red, and the phosphates yellow. Next, cut out all of the shapes and labels and rearrange them below showing the ATP/ADP cycle. Start with ATP at the top. Glue the shapes and then ADD ARROWS to show that this process is a continuous cycle. All shapes and words will be used to build the ATP/ADP cycle.
