Pyruvate split into 2Carbon Molecule, CO₂ released, NADH formed 4. Citric acid breaks into 5-carbon molecule CO2 released NADH formed 3. 2-carbon molecule joins with 4-carbon molecule to form 6carbon citric acid CoA goes back to step 2 2. Coenzyme A (CoA) bonds to 2carbon molecule 5. 5-carbon breaks down to 4-carbon NADH formed ATP formed CO2 released 6. 4-carbon molecule rearranged NADH formed FADH2 formed Question 11 A flattened sac in the chloroplast where the reactions of photosynthesis occur: Thylakoid Chlorophyll Stroma Answer 11 Thylakoid Question 12 carbon dioxide + water + energy → sugar + oxygen Aerobic cellular respiration Photosynthesis Fermentation Answer12 Photosynthesis Question 13 The process in which electrons are transferred from one carrier molecule to another in photosynthesis and cellular respiration; results in production of energy in ATP molecules. Krebs cycle Electron transport system Glycolysis Answer 13 Electron transport system Question 14 What type of carbon-based molecules are most often broken down to make ATP? Sugars Carbohydrates Proteins Answer 14 Carbohydrates Question 15 What is broken down to create Lactic Acid? O₂ Glucose Pyruvate Answer 15 Pyruvate Question 16 What next step does Glycolysis take when it has O₂? When it does not have O₂? Answer 16 Question 17 What are the reactants needed for Cellular Respiration? O₂ & Glucose CO₂ & H₂O Carbon & C₆H₁₂O₆ Answer 17 O₂ & Glucose Question 18 Where do the chemical reactions occur in Cellular Respiration? Calvin Cycle Krebs Cycle Fermentation Answer 18 Krebs Cycle: in the Matrix of mitochondria, breaks down carbonbased molecules Question 19 In Fermentation, the recycling of this allows glycolysis to continue. NADH NADPH NAD⁺ Answer 19 NAD⁺ Question 20 What is added to form NADPH and used to transport H⁺ ions in Photosynthesis? Energized electrons ATP synthase Carbon molecules Answer 20 Energized electrons Question 21 Identify the missing parts of the ETC. 1. 3. 2. 4. 1. H ions transported across membrane. 2. 3. 4. H₂O formed when O₂ picks up electrons & H⁺ Question 22 Why is water important in Photosystem II? Answer 22 H₂O is broken up: O₂ released as waste & H⁺ transported to ETC. Question 23 What is this making? P + ADP Answer 23 ATP Question 24 Define this term: A process by which some organism use chemical energy instead of light energy to make energy-storing carbon-based molecules. Answer 24 Chemosynthesis Question 25 What kind of organism makes its own food? Answer 25 Autotroph Question 26 What are Grana? Answer 26 Stacks of Thylakoids Question 27 Label the products & reactants in Photosynthesis. Where do they take place? Answer 27 Products Reactants sunlight 6H₂O 6O₂ 6CO₂ Sugar Question 28 Cellular respiration needs this unofficial 1st step to start. Answer 28 Glycolysis Question 29 What takes place in and across the inner membrane of a mitochondrion? Answer 29 ETC in CR Question 30 In alcoholic fermentation what is the pyruvate broken down into? Answer 30 CO₂ & alcohol Question 31 How much ATP is produced in fermentation? Answer 31 None, it allows glycolysis to continue which creates 2 ATP.
