Unit Test Review: Photosynthesis and Cellular Respiration

Master photosynthesis and cellular respiration!

Chemical Reactions: Reactants are what go into a chemical reaction and products are what come out of a chemical reaction Photosynthesis (6) Occurs in the chloroplast Reactants = Carbon Dioxide and Water Products = Glucose and Oxygen Occurs in plants only Converts Solar Energy Into Chemical Energy Uses NADPH Has two stems Light reactions Light indenpendant reactions turns light energy into chemical energy Makes food for all living organism Cellular Respiration (6) Occurs in the Mitochondria Occurs in both plants and animals Reactants = Glucose and Oxygen Products = Carbon Dioxide and Water Is an aerobic process Converts Chemical Energy into ATP (usable Energy) has three steps uses NADH Glycolysis Krebs Cycle Electron Transport chain Both Use a membrane for ETC Make ATP Use an electron carrier Match the terms with their correct definition Aerobic Requires oxygen; More ATP produced Anaerobic Does NOT require oxygen; Less ATP produced Fermentation Happens after Glycolysis when oxygen is not present Aerobic Krebs cycle aerobic Electron Transport Chain Fermentation Lactic acid Fermentation Alcoholic Fermentation When oxygen is not present, cells will carry out fermentation in place of cellular respiration. There are two types of cellular respiration; Lactic Acid Fermentation and Alcoholic Fermentation. Complete the sorting activity below to deepen your understanding of the processes: Lactic Acid Fermentation (3) Occurs in humans Causes sore muslces Products are Lactic acid and NAD+ Alcoholic Fermentation (3) Occurs in yeast Used to make bread and yogurt Products are carbon dioxide Both (4) Anaerobic Occurs in the cytoplasm reactants are pruvatic acid and NADH Follows Glycolysis Compare and Contrast Mitochondria and Chloroplast Mitochondria (6) Found in both plants and animals Carries out cellular respiration Takes in oxygen and glucose and produces carbon dioxide and water Makes energy in the form of ATP center of organelle is called matrix folds in the inner membrane are called criste Chloroplast (6) Found in plants but NOT animals Carries out photosynthesis Takes in carbon dioxide and water to produce glucose and oxygen Makes energy in the form of Carbs (C6H12O6) Uses thylakoid membrane for light reactions space surrounding the thylakoids is called stroma Both (3) Have a double membrane contain DNA Contain ribosomes Photosynthesis and Cellular respiration act as a cycle. Use this information to label the picture and complete the sentence below: What organelle is represented by A? ChloroplastWhat process is represented by B? PhotosynthesisWhat product is represented by C? ATPWhat organelle is represented by D? MitochondriaWhat process is represented by E? Cellular RespirationCellular respiration and photosynthesis are considered a cycle because the products of one reaction serve as the reactants for the other reaction. Use the text box to fill in the blanks. Fermentation happen when there is no oxygen in the cell. Fermentation follows the first stem of cell respiration called glycolysis. Fermentation and glycolysis are called anaerobic respiration because oxygen is not required. There are two types fo fermentation Lactic Acid and Alcoholic fermentation . The reactants of fermentation are pyruvateand NADH. The products of Lactic acid fermentation are lactic acid and NAD+. The products of alcoholic fermentation are Alcohol, carbon dioxide and NAD+. There is no ATPmade during fermentaton, the purpose of fermentation is to empty the electron carrier NADH so glycolysis can continue. Light reactions Happens in Thyladoids uses water uses sun light Turns light energy into chemical energy produces oxygen happens only in day produces ATP Produces NADPH Light independant reactions happens in stroma uses Carbon dioxied uses RuBisCo to fix carbon dioxide produces sugar uses ATP Uses NADPH stores chemical energy in carbohydrates happens any time Glycolysis happens in cytoplasm uses 2 ATP Produces 4 ATP Produces Pruvatic Acid Produces NADH splits glucose anaerobic process All organism carry out this process Krebs cycle Happens in the matrix uses pyruvtic acid produces 2 ATP Produces NADH FADH requires oxygen produces carbon dioxide also called citric acid cycle ETC Happens in the inner membrane uses NADH and FADH Produces 34 ATP final electron acceptor is oxygen aerobic process produces water Uses transport proteins to carry electrons creates a h+ ion concentration gradient
