Lectures 1/24,29. Respiration Make a "black box" diagram showing the inputs and outputs of the three main reaction blocks in aerobic respiration; give stoichiometric relationships. Cite the locations of the glycolytic system, the citric acid cycle, and the electron transport system in the cell. Compare respiration with the simple combustion of glucose, and explain the advantage of respiration over combustion in living cells. Describe how a cell maintains its energy supply when it runs out of oxygen. Explain why aerobic respiration is more efficient than fermentation. Describe the arrangement of electron carriers in a mitochondrial electron transport chain. Identify the reaction block in respiration that yields the greatest proportion of the ATP that is produced in respiration. Identify the point in respiration where O 2 enters, and describe what will happen if O 2 is prevented from entering. With diagrams, show what happens to the hydrogen ions and electrons brought in by NADH + H + and FADH 2 as they pass along the electron transport system. Identify "cytochromes" and state what happens if they are prevented from working. Explain the role of chemical/electrical ("chemiosmotic") gradient and describe the effect if these gradient are lost. Indicate which of these groups—prokaryotes, fungi, plants, protists, and animals—have members that can perform respiration and rely on it for the production of metabolic energy. Lectures 1/30-31. Photosynthesis Indicate which of these groups--prokaryotes, fungi, plants, protists, and animals—have members that can perform photosynthesis. Identify the site in the cell where photosynthesis occurs (for both prokaryotes and eukaryotes). Write the structural formula for glucose. Write the overall equation for photosynthesis in green plants; make a "black box" diagram showing the inputs and outputs of the light and dark (light-independent) reactions in green plant photosynthesis; give stoichiometric relationships. Cite the locations of the light and dark reactions within the chloroplast.
