Question
What is the name of the enzyme involved in controlling the rate of cellular respiration? Which two molecules inhibit this enzyme? Under what circumstances do these control mechanisms occur? When is, ATP consumed during respiration? What is the end product of glycolysis? The beginning substrate of the Krebs cycle? How many Carbon atoms does each have? In what molecule is most of the energy in glucose stored before it is used to make ATP? Describe how ATP is produced during oxidative phosphorylation. How is it produced in Substrate level phosphorylation? How is the H+ gradient achieved by the electron transport chain? Where do the H+ ions come from? How are electrons passed through the Electron transport chain? What happens to the electrons at the end of the chain? Describe in general what is happening in Electron transport and Chemiosmosis. At which stages are CO: released during respiration? How arc fats broken down so they can be used for energy? Where in cellular respiration do, their constituents enter? Why are fats such good energy sources? What happens to proteins before they are used in cellular respiration? Where does each stage of cellular respiration take place in the cell? Describe what happens in a muscle cell when there is a lack of oxygen from strenuous exercising. What are the 5 Energy investment steps in Glycolysis? What are the 5 Energy yielding steps in Glycolysis? At which steps is energy being transferred? What are the steps in the Krebs cycle? When is energy being transferred? What happens in the Bridge step between Glycolysis and the Krebs cycle? What is a redox reaction? What role do NADH and FADH2 play in cell respiration? How much ATP is generated from theoretical maximum yield? What happens in Fermentation pathways? How muchExplanation / Answer
2. ATP is consumed during the glycolysis respiratory phase, during phosphorylation of glucose and fructose 6 phosphate , and thus 2 ATP are consumed from the cytoplasm.
3. End product of glycolysis is pyruvate. Beginning product of kreb's cycle is acetyl CoA that is produced from the pyruvate of glycolysis. Pyruvate is a three carbon atom molecule.
5. Substrate level phosphorylation takes place during the preparatory phase of glycolysis, and the during kreb's cycle. In oxidative phosphorylation, ATP is generated after there is oxidation of NADH and FADH2, and electrons are transferred and protons are pumped. In substrate level phosphorylation, , ADP is directly phosphorylated with a phosphate group and energy is provided from a coupled reaction.
6. The H+ gradient is achieved by chemiosmosis across a selectively permeable membrane. The H+ ions pass through the inner mitochondrial membrane using ATP synthase. The hydrogen ions are present in the surrounding medium.
8. CO2 is produced during the stage of cellular respiration.
