Question

Photosynthesis and Cell respiration Worksheet Photosynthesis: lWrite the general reaction for photosynthesis. Are the chemical reactants and products balanced? 2) Prepare a rough drawing of a chloroplast labeling the following: chloroplast, grans, thylakoid membrane, stroma 3) What links photosystem I and photosystem 11? What is the purpose of this link? 4) Consider what happens when light is absorbed by the pigments of photosystem ll; How are electrons affected by the light absorption? Where do the excited electrons go? 5) In just 3-4 sentences summarize the light-dependent reactions. What are the two most important products? 6) What is the overall purpose of the Calvin Cycle? 7) Where does CO2 enter the cycle? 8) How are ATP and NADPH used? 9) G3P (also called PGAL) can be used to from glucose, but most is recycled. Why? Cell Respiration: 1) Write out the overall equation to cell respiration compare it to the equation for photosynthesis List four phases of cell respiration 3) 2) What are the starting and ending products of glycolysis 4) 4) In what situation is pyruvic acid reduced to lactic acid? 5) What happens to animal cells when too much lactic acid accumulates n muscles? How the muscle cells solve the problem? 6) In aerobic respiration, pyruvic acid continues on to cell respiration. Where doe this dccur? How is pyruvic acid changed prior to entry in the Krebs cycle? 7) In what part of the mitochondrion do the events of the Krebs cycle occu4r? 8) What molecule actually enters the cycle? 9) What is the role of enzymes in the Krebs cycle? 10) Where is CO2 removed? What becomes of it? 11) What molecule accepts the electrons after they pass through the electron transport chain? 12) How much ATIP is produced in cell respiration overall, and in each of the stages? 13) Prepare a drawing of a mitochondrion, labeling the following: outer membrane, inner membrane, and where the different stages occur
