Cellular Respiration/Fermentation Review Game Question 1 The process that releases energy from food when oxygen is present? Cellular Respiration Question 2 Which organisms can undergo cellular respiration? Autotrophs and heterotrophs Question 3 By the end of glycolysis, glucose is broken down into? 2 pyruvates (pyruvic acid) Question 4 What is needed in order for glycolysis to take place? 1. glucose 2. ATP 3. NAD+ 4. ADP Question 5 Where does cellular respiration take place in a cell? Mitochondria Question 6 What is the relationship between cellular respiration and photosynthesis? They are opposites of each other. They depend on each other. What is produced in one is used in the other and vice versa. Question 7 What is the first step in the catabolism of glucose called? Glycolysis Question 8 What are the steps of cellular respiration? 1. Transition Reaction 2. Kreb’s Cycle/Citric Acid Cycle 3. Electron Transport Chain (ETC) Question 9 Type of organism that needs to eat other organisms in order to get their energy? Heterotroph Question 10 The process that releases energy from food when oxygen is not present? Fermentation Question 11 Where does fermentation take place? Cytoplasm Question 12 How many ATP are generated from 1 glucose molecule as a result of glycolysis and cellular respiration? 36 ATP Question 13 What is a “waste product” that is produced during the transition reaction? CO2 Question 14 What is needed in order for the Kreb’s Cycle to take place? 1. Acetyl Co-A 2. NAD+ 3. FAD 4. ADP Question 15 How many times must the Kreb’s Cycle occur for every molecule of glucose? 2x Question 16 How many ATP are generated from glycolysis and fermentation? 2 ATP Question 17 Name the types of fermentation. 1. Lactic Acid Fermentation 2. Alcoholic Fermentation Question 18 Which of the following best describes the energy conversion in cellular respiration? A. Light energy is converted to chemical energy in food B. Chemical energy in food is converted to usable energy C. Heat energy is converted to food energy D. Light energy is converted to heat energy B- Chemical energy in food is converted to usable energy Question 19 What is the food molecule that is being broken down in cellular respiration? Glucose Question 20 What molecules are needed for cellular respiration to take place? Glucose and Oxygen Question 21 What is produced as a result of cellular respiration? Carbon dioxide, water and energy (ATP) Question 22 A process that requires oxygen is referred to as? Aerobic Question 23 Which of the following is NOT produced during glycolysis? A. ATP B. Pyruvate C. FADH2 D. NADH C. FADH2 Question 24 Which step of cellular respiration generates the MOST ATP? Electron Transport Chain Question 25 How many net ATP are generated in glycolysis? 2 ATP Question 26 The two electron carriers that are involved in cellular respiration and travel to the ETC are called? NADH and FADH2 Question 27 How many ATP are generated in each step of cellular respiration? 1. transition reaction- none directly 2. Kreb’s Cycle-2 ATP 3. ETC- 32 ATP Question 28 What process takes place at #2? glycolysis Question 29 What molecule is waiting to accept electrons at then end of the electron transport chain? Oxygen Question 30 Which of the following is TRUE of lactic acid fermentation? A. Produces carbon dioxide B. Needs oxygen C. Occurs in muscle cells D. Does not help the cell in any way C-occurs in muscle cells Question 31 What molecule is made into lactic acid or ethanol when oxygen is NOT present? Pyruvate Question 32 Which of the following is a difference between photosynthesis and cellular respiration? A. Photosynthesis uses light energy B. Photosynthesis only occurs in heterotrophs C. Cellular respiration makes oxygen D. Cellular respiration makes glucose A. Photosynthesis uses light energy Question 33 Which of the following is TRUE of alcoholic fermentation? A. Produces carbon dioxide and ethanol B. Produces oxygen C. Occurs in muscle cells’ D. Helps make yogurt A. Produces carbon dioxide and ethanol Question 34 Where does glycolysis take place? Cytoplasm Question 35 Is glycolysis aerobic or anaerobic? Anaerobic Question 36 Is cellular respiration aerobic or anaerobic? Aerobic Question 37 During which phase/step of cellular respiration is oxygen needed? ETC Question 38 What is represented by #12? ATP Question 39 What is the chemical equation for cellular respiration? C6H12O6 + O2CO2+ H2O+ ATP Question 40 What is represented by #5? ETC Question 41 What is the MAIN function of cellular respiration? A. To make water B. To turn glucose into ATP C. To produce carbon dioxide D. To break down ATP B. To turn glucose into ATP Question 42 What is represented by #4? Kreb’s Cycle Question 43 What number would represent carbon dioxide? 10 Question 44 Which process (aerobic or anaerobic) is more efficient at converting the energy stored in food molecules into ATP? Aerobic (cellular respiration) is more efficient because it produces 36 ATP as opposed to 2 ATP from glycolysis + fermentation (anaerobic) Question 45 What would be leaving #2 and heads to #5? NADH Question 46 True or False: Breathing and cellular respiration are the same process? FALSE-they are related to each other. Breathing is the exchange of gases and cellular respiration is how organisms break down food to release energy. Question 47 By the end of the Kreb’s Cycle, how much of the original glucose still exists? All of the Carbons and Oxygen have been removed in the form of CO2. The Hydrogens are being carried by NADH and FADH2 to the ETC.
