1 1 Which pathway for aerobic cellular respiration is located in the cytoplasm of the cell? glycolysis citric cycle 2 Which of the following statements is NOT correct regarding aerobic cellular respiration? Cells would lose too much energy as heat if they used glucose directly for individual reactions. Cells would lose too much energy as nonusable heat if they used glucose directly. Cells are able to utilize all the energy from glucose when released in one burst. 3 Gradual glucose breakdown releases energy slowly. Gradual glucose breakdown allows for the simultaneous build-up of many ATP molecules. Which of the following pathways does NOT occur in aerobic cellular respiration? glycolysis 4 Which of the following statements is correct? NAD is reduced and becomes NADH 2 when it accepts hydrogen atoms. NAD is oxidized and becomes NADH when it accepts hydrogen atoms. NAD is reduced and becomes NADH 2 when it releases hydrogen atoms. NADH 2 is reduced to NAD when the hydrogen atoms are passed to another acceptor.
2 5 Which of the following statements is NOT correct about glycolysis? Glycolysis takes place within the cytoplasm. Glycolysis uses two ATP but forms four ATP, resulting in a net gain of two ATP molecules. During glycolysis, two NADH are produced as substrate oxidation occurs. 6 Glycolysis begins with glucose and ends with four pyruvate molecules. Pyruvate is the end product of the reactions. glycolysis 7 Glycolysis can be used in both aerobic cellular respiration and fermentation. True 8 False Which of the following pathways will use coenzyme A during aerobic cellular respiration? glycolysis 9 fermentation Which of the following pathways will result in carbon dioxide and NADH 2 being released but not ATP? glycolysis
3 10 How many times does the turn per glucose molecule? once twice three times four times 11 five times Which pathway will result in the production of four carbon dioxide molecules, two ATP molecules, NADH 2 and FADH 2? glycolysis 12 Which molecule is the final acceptor of electrons at the end of the in aerobic cellular respiration? oxygen carbon dioxide lactate citrate 13 pyruvate Based on chemiosmosis, hydrogen ions accumulate in the of the mitochondrion to create a large electrochemical gradient for aerobic cellular respiration. intermembrane space
4 intramembrane space cristae matrix 14 stroma What molecule will form when hydrogen ions flow down the electrochemical gradient through ATP synthase complexes in mitochondria? water ATP ADP carbon dioxide 15 oxygen Which of the following pathways and reactions will result in the production of the most ATP molecules during aerobic cellular respiration of one glucose molecule? glycolysis 16 fermentation is a series of enzymatic reactions by which glucose is incompletely metabolized to lactate or carbon dioxide and alcohol. Fermentation Aerobic cellular respiration The The Glycolysis
5 17 and are two conenzymes of oxidation-reduction that are active during cellular respiration. NAD+, FAD ATP, FAD ATP, NAD+ 18 FAD, ADP A total of ATP molecules are produced per glucose molecule in cellular respiration The and are located in the of the mitochondria. intramembrane space matrix cristae 20 outer membrane Fermentation is essential to humans because it. produces lactate produces alcohol provides a rapid burst of ATP provides a continuous supply of ATP
3. Distinguish between aerobic and anaerobic in terms of cell respiration. Outline the general process of both.
3.7 Cell Respiration 1. Define cell respiration. Cell respiration is the controlled release of energy from organic molecules in cells to form ATP. 2. State the equation for the process of cell respiration.
