Cellular Jeopardy Show me the light! Energy baby! Captain - I’m giving it all she’s got! 10 10 10 10 10 20 20 20 20 20 30 30 30 30 30 40 40 40 40 40 50 50 50 50 50 True or false Everything else Final Jeopardy 10 points During light independent reactions of photosynthesis, light energy is used to split water molecules generating protons and oxygen molecules. 10 points False, in light Dependent a water splits into H+, Oxygen, and an electron 20 points C4 plants keep their stomata open during hot days to allow for sufficient uptake of Carbon Dioxide to minimize water loss 20 points False, C4 keep their stomata open either at night or on cooler days to minimize water loss 30 points The first stage of cellular respiration is called glycolysis 30 points True! It does not need oxygen 40 points Glycolysis is an anaerobic process, which means it does not need oxygen to occur 40 points True, no oxygen is needed for glycolysis to occur, and it happens in ALL organisms – bacteria, yeast, animals, plants, and you! 50 points A prokaryote that grows and reproduces without oxygen is called aerobic 50 points False, without oxygen is called Anaerobic 10 points This is the energy currency of the cell 10 points ATP 20 points Flattened saclike membranes that are arranged in stacks in the chloroplast 20 points Thylakoids 30 points The study of the flow and transformation of energy in the universe 30 points Thermodynamics 40 points The second law of thermodynamics states that energy cannot be transformed without this being lost to the environment 40 points Heat energy is lost to the environment, called entropy 50 points The photosynthetic pathway used by the saguaro cactus 50 points CAM 10 points the final electron acceptor in photosynthesis 10 points Ferrodoxin 20 points Energy is transferred from Light dependent reactions to the light independent reactions by these two molecules 20 points ATP and NADPH 30 points True or false: Thylakoid membranes have a large surface area that provides the space needed to hold large numbers of electron-transporting molecules 30 points True! Thylakoids have a large surface area needed to hold many electron carrying molecules 40 points The 2 molecules that are created in the thylakoids and are then consumed by the reactions in the stroma? Need 2 answers 40 points ATP and NADPH 50 points Light absorbing molecules that are found in the thylakoid membrane of photosynthetic organisms 50 points Pigments that includes Chlorophyll a and b, and carotenoids 10 points A corn plant is an example of this type of plant 10 points C4 20 points The final electron acceptor for the electron transport chain during cellular respiration 20 points oxygen 30 points If oxygen is available after glycolysis, aerobic respiration will occur in this organelle 30 points mitochondria 40 points If you place an aerobic organism in an anaerobic environment, what process will be the first to stop working? 40 points An aerobic organism in an anaerobic environment will have the electron transport chain stop, this will then stop the Kreb cycle/citric acid cycle (and lactic acid fermentation will now occur) 50 points Where does the oxygen used in cellular respiration end up? 50 points Oxygen ends up in water 10 points The first stage in the breakdown of glucose in all organisms 10 points glycolysis 20 points What do cells use as their main source of chemical energy 20 points ATP 30 points Where does glycolysis occur? 30 points Glycolysis occurs in the cytoplasm, along with fermentation 40 points This waste product of photosynthesis is released into the environment 40 points oxygen 50 points Which process, photosynthesis and/or respiration, utilize the actions of enzymes 50 points BOTH photosynthesis and respiration need ENZYMES to occur Final Jeopardy In humans, Explain all possibilities of the steps that may follow glycolysis (include both with and without oxygen) Final Jeopardy Answer If oxygen is not present, lactic acid fermentation will occur creating a yield of only 2 ATP’s and replenishing the NAD+ so glycolysis can continue. If oxygen is present, then the pyruvate enters the mitochondria and aerobic respiration will yield 36 ATP’s
