EOC Review: Photosynthesis, Cellular Respiration & ATP

Master Photosynthesis & Cellular Respiration! Understand ATP, organelles, and energy flow.

Photosynthesis and Cellular Respiration Use the review video and your notes from earlier this year, to help you answer the questions below. The review questions cover the most important content from this unit. Fill in the Blanks:Choose the correct term to fill in the blanks below.Chemical Reactions: Reactants are what go into a chemical reaction and products are what come out of a chemical reaction Sort each term into the correct part of the T-Chart below. Photosynthesis (6) Occurs in the chloroplast Reactants = Carbon Dioxide and Water Products = Glucose and Oxygen Makes food for plant cells Occurs in plants only Converts Solar Energy Into Chemical Energy 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) Compare and Contrast Mitochondria and Chloroplast Mitochondria (4) 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 Chloroplast (4) 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) 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 interrelated because the products of one reaction serve as the reactants for the other reaction. ATP Fermentation Match the terms with their correct definition Aerobic Requires oxygen; More ATP produced Anaerobic Does NOT require oxygen; Less ATP produced Fermentation Glycolysis when oxygen is not present 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 (2) Occurs in humans Causes sore muslces Alcoholic Fermentation (2) Occurs in yeast Used to make bread and yogurt Both (2) Anaerobic Occurs in the cytoplasm Photosynthesis Cellular Respiration Interrelatedness How are cellular respiration and photosynthesis related, in terms of energy? The energy transformed in photosynthesis is used to power cellular respiration. The energy transformed in cellular respiration is used to power photosynthesis. Photosynthesis and respiration perform the same task in terms of energy transformation. Energy is not involved in either photosynthesis or cellular respiration. In which way are photosynthesis and cellular respiration different? Cellular respiration stores ATP, while photosynthesis releases ATP. Cellular respiration produces oxygen, while photosynthesis uses oxygen. Photosynthesis releases energy, while cellular respiration stores energy. Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide. The diagram below shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur.Which statement describes how photosynthesis and cellular respiration are interrelated? Oxygen is produced during cellular respiration and stored during photosynthesis. Carbon dioxide and water released by cellular respiration are used in photosynthesis. Photosynthesis releases the energy that is stored during the process of cellular respiration. Glucose is used during cellular respiration to produce food that is broken down duringphotosynthesis. Which of the following structures is where cellular respiration occurs in the cell below? nucleus cytoplasm mitochondria vacuoles Mike has four aquatic plants of the same size and the same species. He submerges the plants in a separate beaker filled with 200 ml of water. He then sets each beaker under a different intensity of light.Mike observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 minute period.Which of the following statements best explains Mike’s observations? Cells decompose most quickly under the most intense light. Water evaporates from plants faster under the most intense light. Photosynthesis occurs at the highest rate under the most intense light. Gases in the leaves of plants expand most under the most intense light What function does ATP carry out in living things? aids in protein folding and coiling used to capture and transfer energy identifies DNA start sequences for transcription helps maintain the fluidity of cell membranes Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations? Only species Y is aerobic. Only species Y is anaerobic. Both species X and Y are aerobic. Both species X and Y are anaerobic. A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles.Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event? As the cells run out of oxygen they switch to anaerobic respiration, which allows the cell to make small amounts of ATP in the absence of oxygen. As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells. The cells will never run out of oxygen if the weightlifter is breathing. As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP. Which process do animals use to convert energy from food into ATP? osmosis photosynthesis cellular respiration transcription Which process takes place in the presence of oxygen and produces nearly 20 times as much as ATP as glycolysis alone? photosynthesis lactic acid fermentation alcoholic fermentation aerobic respiration
