Photosynthesis/Respiration Test Review Answer Key 1/12/16 Page 1 Matching: 1. 2. 3. 4. 5. 6. 7. 8. Thylakoid Calvin cycle Electron transport chain Photosystem Light-dependent reaction Chlorophyll ATP is the product of the light-dependent reactions Glucose is the product of the light-dependent reactions NOTE the light-dependent reactions happen BEFORE the light-independent reactions The Calvin Cycle produces sugars from carbon dioxide Page 2 Stepped out vocabulary 0. ATP = adenosine triphosphate. It is a high energy molecule. It is the currency of energy in living things 1. Aerobic= “with oxygen” It refers to a process that NEEDS OXYGEN 2. Glycolysis= splitting of glucose (lysis=splitting) ATP is formed when this happens. It does NOT need oxygen 3. ADP = adenosine diphosphate, a low energy molecule 4. Fermentation=cellular respiration WITHOUT oxygen. It allows glycolysis (cellular respiration) to continue but it does not make ATP 5. Cellular respiration=the breaking down of sugars to make ATP. In other words it is how energy is made from the food we eat. 6. Anaerobic =”without oxygen” ex: fermentation occurs when there is not oxygen 7. Krebs cycle= breaks down carbon based molecules to move to the electron transport chain (we will talk more about this in the next lesson) 8. Lactic Acid= product of fermentation. It is what makes your muscles feel a “burn” when you are working out. It is a waste product of fermentation and is used to make yogurt. Page 3: Word origins: note that many words come from Latin and Greek. Knowing the origins and what parts of the words mean will help you remember them. 1. 2. 3. 4. 5. 6. Relating to air Relating to no air Light system Put together with chemicals Put together with light Putting ATP together Page 3 1. D2;A1 2. 3. 4. 5. D5;A5 D1;A2 D4;A3 D3;A4 Page 4 3A. reactants photosynthesis: carbon dioxide, water, 3B.products of photosynthesis: sugar, oxygen 3C.Reactants in respiration: sugar, oxygen 3D.products Respiration: water, carbon dioxide 4. They are mirror images. Products of respiration and the reactants for photosynthesis and vice versa 5. Plants produce sugars and oxygen, which animals need to live. Animal wastes are used by plants for the resources they need to live. 6. Diagram: starting with the tree and going counterclockwise (following the arrows) Photosynthesis, oxygen goes to the cow, cellular respiration is what the cow is doing, glucose is what the cow is getting from the grass, ATP is the energy molecule that goes in the “star” box, carbon dioxide is what the plant takes in. Enzymes end in –ase, sugars end in -ose Review the equation for photosynthesis and for cellular respiration Know endocytosis, exocytosis and phagocytosis Know the meaning of the words on page 1. Do not worry about chemosynthesis, photosystems, electron transport chain Know: ****cellular respiration, photosynthesis, cell membrane fluid mosaic model, anaerobic, arerobic, FACULTATIVE ANAEROBE, fermentation, lactic acid, endocytosis, exocytosis, phagocytosis.
