Cellular Respiration POGIL Answers_2023.
Cellular Respiration POGIL Exam: Spring 2023. What is represented by the hexagon? How many carbon atoms (C) are in one molecule of glucose? How many carbon atoms (C) are in one molecule of pyruvic acid? In the process of glycolysis, what happens to glucose after it crosses the cell membrane into the cytoplasm of the cell? - Thinking about the number of carbon atoms in glucose and in pyruvic acid, explain why there is one molecule of glucose on the left side of the arrow and two molecules of pyruvic acid on the right side of the arrow. How many ATP molecules are produced during glycolysis? Hydrogen-carrying molecules are also produced during glycolysis. What is the symbols of these hydrogen-carrying molecules? Does glycolysis occur inside or outside the mitochondria? According to Model 2, what happens to pyruvic acid during the Kreb's cycle? According to Model 2, where does the change identified in the previous question occur? Note the number of atoms of carbon in pyruvic acid and explain why three molecules of carbon dioxide are produced. Considering the glycolysis produces 2 pyruvic acid molecules per glucose molecule, how many total CO2 molecules will be produced from the complete breakdown of each glucose molecule? Show a mathematical equation to support your answer. What 2 hydrogen carrying molecules are formed during the Kreb's cycle? Glycolysis Kreb's cycle (1st pyruvic acid) Kreb's cycle (2nd pyruvic acid) - What cell structure is the site for the electron transport chain? What substance do the carrier proteins transport across the inner mitochondrial membrane? - What high energy molecules are formed by the electron transport chain? - What atom accepts the hydrogen ion at the end of the electron transport chain? - What molecule is formed as a product of that acceptance? - Formulate an explanation for why the events of the ETC constitute an aerobic process rather than an anaerobic process (like glycolysis) - Glycolysis - Kreb's Cycle - ETC - Total ATP Produced - Grand Total ATP Produced (Add all 3 columns above) - C6H12O6 - 6O2 - 6CO2 - 6H2O - 38 ATP Compare the ATP available to cells when oxygen is present versus when it is absent. How might this help explain why brain and heart functions are so quickly affected when a person cannot breathe? What are the two substances that may be formed in anaerobic respiration? Recall that two molecules of ATP are formed during glycolysis. Neither fermentation process shown above creates any more ATP. Knowing this, what would you Predict about the cellular energy available to organisms that carry out fermentation? Research the relationship between overexertion of muscles and the formation of lactic acid. How does this relate to "the burn" felt during strenuous activity? What common foods involve the process of fermentation? Use your text or other resource to make a list of the foods and the specific organic organisms used.
