Photosynthesis and Cellular Respiration Worksheet

NAME______________________ Photosynthesis and Cellular Respiration Worksheet Part A. Write the correct term from the list below in the space next to the definition. ATP Autotroph/ Producer energy-carrying molecule that cells use to power their metabolic processes organism that makes its own food Cellular Respiration process in which cells break down glucose and make ATP for energy Glucose simple carbohydrate with the chemical formula C6H12O6 that is the nearly universal food for life Heterotroph/ Consumer Photosynthesis organism that consumes other organisms for food process of using the energy in sunlight to make food (glucose) Stroma space outside the thylakoid membranes of a chloroplast where the Calvin cycle of photosynthesis takes place Thylakoid membrane in a chloroplast where the light reactions of photosynthesis occur Chlorophyll green pigment in a chloroplast that absorbs sunlight in the light reactions of photosynthesis Chloroplast Organelle in the cell in which the process of photosynthesis takes place Mitochondria Organelle in the cell in which the process of aerobic cellular respiration occurs Part B. Label the following parts of the chloroplast below: thylakoid, granum, stroma ABC- Stroma Thylakoid Granum Part C. Formulas and equations!! 1. What is the chemical equation for photosynthesis? Identify the reactants and the products. 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 2. What is the chemical equation for cellular respiration? Identify the reactants and the products. C6H12O6 + 6O2 → 6CO2 + 6H20 + (energy) 3. How are equations above the similar? How are they different? Products of photosynthesis are the reactants of cellular respiration. The products of cellular respiration are the reactants of photosynthesis 4. What is the chemical equation for alcoholic fermentation? C6H12O6 → 2 C2H5OH + 2 CO Part D. Fill in the diagram showing photosynthesis below using the following terms (NOTE: 1 term will be used twice): Calvin Cycle, ATP, Oxygen, NADH, Thylakoid membrane, Light, Light -Dependent, LightIndependent, Glucose, Water, Stroma, and CO2 Water Sunlight “Light” Reaction also known as Light Dependent Reactions Identify location: Thylakoid Oxygen NADPH ATP “Dark” Reaction also known as Calvin Cycle Or Light-Independent reactions Identify location: Stroma Glucose Using the diagram above, answer the following questions. 1. What are 2 waste products? Oxygen, ATP CO2 2. What are two products that are recycled back to the Light Dependent reaction from the Light Independent reaction? (NOTE: They are not mentioned in the diagram) NADP+ and ADP+P 3. What organism does this process occur in? plants______________________ What specific location within the cell does this occur in? chloroplasts_ Vocabulary to know: Aerobic respiration type of cellular respiration that requires oxygen Anaerobic respiration type of cellular respiration that does not require oxygen Glycolysis first stage of cellular respiration in which glucose is split, in the absence of oxygen, to form two molecules of pyruvate (pyruvic acid) and two (net) molecules of ATP second stage of aerobic respiration in which two pyruvate (pyruvic acid) molecules from the first stage react to form CO2, water, and 2 ATP Third stage of aerobic respiration in which 32 ATP are formed Krebs cycle (Citric Acid cycle) Electron Transport Chain 2. What is cellular respiration? What processes are involved? Which organelle does cellular respiration take place in? Process that releases energy by breaking down food molecules in the presence of oxygen. Processes involved = glycolysis, krebs cycle, electron transport chain. Mitochondria. 3. Understand that glycolysis begins the process of releasing energy from glucose. Where does it take place? Cytoplasm of the cell outside the mitochondria. 4. What is produced during glycolysis? Where does the product go after glycolysis Pyruvic acid; to the Krebs cycle in aerobic conditions/ to fermentation in anaerobic conditions. 5. What type of process is glycolysis: aerobic/ anaerobic? 6. What types of organisms go through cellular respiration: eukaryotes/ prokaryotes? BOTH ☺ 7. Look at the diagram below: What occurs in Boxes A, B, C? How much ATP do each of them produce? What process is taking place? What organelle is shown? A B Box A- Glycolosis produces 2 ATP- cytoplasm Box B- krebs Cycle produces 2 ATPmitochondria Box C- Electron Transport Chain 32 ATPmitochondria C Part E.
