Cellular Respiration: Done by all organisms Aerobic Cellular Respiration: C6H12O6 + 6O2 --> 6CO2 + 6 H2O (makes 34-38 ATP) Take place in the mitochondria Reactants: Sugar and Oxygen Products: Carbon Dioxide and Water (and ATP) The purpose of cellular respiration is to make ATP- which is used for immediate energy by the cell when a bond is broken and one phosphate leaves...turning ATP to ADP. Aerobic Cellular Respiration (with oxygen) makes 34-38ATP The 3 stages of Aerobic Respiration are Glycolysis, Kreb Cycle, and Electron Transport Chain. Glycolysis takes place in the cytoplasm. It splits glucose into pyruvate and makes 2 ATP. The Kreb Cycle takes place in the mitochondria. It makes some ATP and uses oxygen. It makes NADH and FADH2 to transport to the elecrton transport chain. The electron transport chain makes LOTS of ATP. It uses oxygen to and causes ATP Synthase (enzyme) to add a phosphate onto ADP to make ATP. This takes place in the mitochondria. Law of Conservation of Matter: Matter (atoms) cannot be created or destroyed...they can be rearranged to make new molecules. Law of Conservation of Energy: Energy cannot be created or destroyed. It can be transferred from one type of energy (chemical energy) to another (mechanical energy) Anaerobic Respiration (without oxygen) makes 2 ATP Animals do Lactic Acid Fermentation (without oxygen)- makes lactic acid. Lactic acid causes cramps in muscles that have used up their oxygen supply. Bacteria and Yeast do Alcoholic Fermentation (without oxygen- makes alcohol and carbon dioxide) or Lactic Acid fermentation Anaerobic respiration takes place in the cytoplasm. Glucose is broken apart to make pyruvic acid. The pyruvic acid is then converted either into lactic acid or ethanol and CO2. It takes 2 ATP for the process to go and makes a total of 4 ATP. The Net Gain is 2 ATP for Anaerobic respiration. Photosynthesis Notes for quiz: Tropism: Movement of plant towards or away from a stimulus phototropism- movement towards light gravitropism- movement away (stem) or towards (roots) the pull of gravity Parts of a Plant: Water enters a plant through the ROOTS, travels through the XYLEM on the way to the leaves. The path of water is soil, roots, stem, leaves. Carbon Dioxide and Oxygen enter and exit a plant through the STOMATA on the undersides of the leaves. Sugar is made in the chloroplast in the leaves of a plant. Sugar travels in the PHOLEM throughout the plant. The transport tissues in plants are the xylem (water) and the pholem for sugar. Photosynthesis: Done by Producers 6CO2 + 6 H2O (+ light) --> C6H12O6 + 6 O2 Photosynthesis uses light energy, carbon dioxide and water to make sugar and oxygen. Reactants: Carbon dioxide and water (light needed as energy source) Products: Sugar and Oxygen Photosynthesis takes place in the chloroplast of plant cells and some other producers. Autotrophs/Producers do photosynthesis (Plants, some protists and some bacteria) The purpose of photosynthesis is to make food (glucose- organic molecule) for the producer. Sugar that is not used in cellular respiration is used to build the biomass of the plant. Adding light, or CO2 will increase the rate of photosynthesis in plants. You can measure this by the amount of oxygen bubbles given off in an aquatic plant, or by the growth (biomass) of the plant. Stages of photosynthesis: Light Reactions-- Takes place in the Grana in the chloroplast. The Chlorophyll (pigment) uses light to split water and release oxygen. ATP and NADPH is made and used in the Calvin Cycle. Calvin Cycle-- Takes place in the Stroma of the chloroplast. Sugar is made from CO2 molecules and the H from the water. Cycles and Energy Matter Cycle (atoms/molecules- such as water, carbon, and nitrogen). Energy flows from the sun to producers, to primary consumers and up the food chain. Abiotic: Nonliving factor...such as gas in the atmosphere, evaporation, precipitation, water, carbon dioxide, nitrogen gas Biotic: Living factors...photosynthesis from plants, cellular respiration, decomposition, bacteria Cycle vocabulary: Geosphere: Sediment (soil) and Rocks. Lots of carbon is stored in the geosphere. It is released through burning fossil fuels. Decomposers can add carbon to the geosphere. Biosphere: All living organisms. Plants do photosynthesis which removes carbon from the atmosphere. All organisms do cellular respiration which adds carbon to the atmosphere. Decomposers recycle carbon back into the sediment (geosphere). Atmosphere: Gases around the earth. Increased CO2 in the atmosphere leads to global warming. CO2 is removed from the atmosphere by photosynthesis. It is added to the atmosphere by cellular respiration, and burning of fossil fuels. Hydrosphere: Water CO2 can dissolve into the oceans. It can also be released from the ocean back into the atmosphere. Carbon Cycle: Carbon Dioxide in found as a gas in the air. Carbon molecules make up the backbone of all organic molecules. Photosynthesis: Takes Carbon Dioxide in the air and changes it into sugar in producers. Biosynthesis: Organisms use the sugar to build their biomass (make larger molecules to build cells). Biosynthesis creates polymers from monomers. Builds lipids, proteins, carbohydrates and nucleic acids. Cellular Respiration: Animals/Plants (all organisms) use sugar to make ATP. Carbon Dioxide is released back into the atmosphere Decomposition: When organisms die the carbon is recycled back into the ground Burning Fossil Fuels takes carbon that has been stored in the ground and releases it into the atmosphere. This can lead to increased greenhouse gases and global warming. Water Cycle- Transpiration: Water evaporating from the leaves of plants Evaporation- Water changing from liquid to gas Condensation- Water changing from gas to liquid (forms clouds) Precipitation- Water falling from the sky (in any form) Runoff- Water moving over the surface of the ground. Plants decrease runoff. Nitrogen Cycle: Nitrogen is found as a gas in the atmosphere. Nitrogen is an important part of living organisms proteins and nucleic acids. Nitrogen Fixation: Nitrogen is moved from the atmosphere to the soil by Nitrogen Fixing Bacteria in the Root Nodules of Legumes. Bacteria are important in changing the form of nitrogen in the soil so that they can be used by plants Denitrification: Bacteria take nitrogen from the soil and release it back into the air as a gas. Eutrophication: Too much nitrogen in the water (from runoff) can lead to algae blooms. When the algae dies and decomposes the bacteria use all the oxygen in the water and lead to dead zones in the water where nothing can live or grow. Animals: Consumption- Takes in water, carbon dioxide, and nitrogen (eating) Biosynthesis- Animals build up polymers from monomers to make complex carbohydrates, protein, lipids and nucleic acids. Cellular Respiration- Animals do aerobic cellular respiration in the mitochondria to release energy from sugar. Circulatory System- Animals transport gases, food, and waste in the circulatory system. (similar to xylem and phloem in the plant) Digestive System- Animals break down polymers into monomers in the digestive system. |
