Organic Molecules What atoms make up the 4 organic molecules? (see the elements row above) Carbon,hydrogen,oxygen,nitrogen,phosphorus and sulfur are the atoms that make up these 4 molecules. Organic Molecules What are the 4 organic molecules and their monomers? (Use previous slide for help) Carbohydrates-Monosaccharides Proteins-Amino acids Nucleic acids-Nucleotides Lipids-fatty acid Elodea Lab Plants perform photosynthesis using the energy from sunlight. Fill in the yellow boxes with the reactants and products of photosynthesis sun 6CO2 6H2O C6 H12 O6 6O2 Carbon dioxide Water Sugar/gluc Oxygen ose Elodea Lab The more sunlight the plant receives, the __more_________ photosynthesis it performs. Plants performing more photosynthesis produce ___more________ oxygen. Mealworm Lab. All living organisms perform cellular respiration to release the energy in glucose. Fill in the yellow boxes with the reactants and products of cellular respiration. Sugar Oxygen Carbon water ATP dioxide Mealworm Lab The mealworms ate the potato, Mealworm Lab transferring ____energy_____ from the potato to the mealworm. We knew this because the mealworms _increased_in__ weight and potato ____decreased in ___weight. Cellular respiration rearranged the C6 , ___H12 _____ and ___06______ in the glucose and oxygen and created ATP, CO2 and H20. We know ____carbon dioxide ____ was created because the BTB turned yellow. Yeast Demonstration (Anaerobic Respiration) How do we know the glucose was rearranged and Carbon Dioxide was produced? We know that glucose was rearranged because the sugar from glucose was being used with the yeast that produced carbon dioxide. Yeast Demonstration (Anaerobic Respiration) Why might the yeast that was given 0 sugar still have been able to perform some anaerobic respiration? Yeast can sometimes store energy from previous sugars in the form of glycogen. This can help it contact without the need for direct contact with sugar. Yeast Demonstration (Anaerobic Respiration) Yeast perform ____anaerobic______ ____ respiration and produce things like wine, beer and bread. They produce ___carbon dioxide___ as a byproduct. Yeast Demonstration Bacteria like aspergillus and lactobacillus also perform _________anaerobic respiration_____ (Anaerobic respiration and help make soy sauce and yogurt Respiration) But some bacteria perform _____aerobic_________ respiration, like the bacteria that create dead zones (recall our Chesapeake Bay and Oyster lessons). Recall that there was an overgrowth of algae due to less oysters and extra nutrients like nitrogen. Then the bacteria decompose the algae (providing _____organic matter______ for the bacteria). They also use _____oxygen____to fuel the cellular respiration process. Using up all of the ___oxygen_ ______ creates the dead zones where animals like oysters, fish, crabs cannot survive.
