Metabolic Processes - Making Connections Questions

METABOLIC PROCESSES – Making Connections CURRICULUM EXPECTATIONS: • C1.1 Analyse the role of metabolic processes in the functioning of and interactions between biotic and abiotic systems (e.g., specialized microbes and enzymes in biotechnological applications to treat wastewater in the pulp and paper industry; microbes and enzymes in bioremediation, such as in the cleanup of oil spills; energy transfer from producers to consumers) • C1.2 Assess the relevance, to their personal lives and to the community, of an understanding of cell biology and related technologies (e.g., knowledge of metabolic processes is relevant to personal choices about exercise, diet, and the use of pharmacological substances; knowledge of cellular processes aids in our understanding and treatment of mitochondrial diseases [a group of neuromuscular diseases]) BIOREMEDIATION – Use of Microbes and Enzymes to Clean an Oil Spill 1. What is bioremediation? Bioremediation - __________________________________________________________________ _______________________________________________________________________________ 2. What type of microbes are used to clean up an oil spill? ___________________________________ _______________________________________________________________________________ 3. What is the role of enzymes in bioremediation? _________________________________________ _______________________________________________________________________________ 4. Explain how microbes (biotic) “clean up” the oil (abiotic). Note: Oil is a nonpolar molecule made up of carbon and hydrogen atoms ______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ EXERCISE, DIET AND USE OF PHARMACOLOGICAL SUBSTANCES 1. How does exercise affect the rate of cellular respiration? Increases rate Decreases rate No effect on rate 2. Read the following passage and use the word box to fill in the blanks. Note: Not all words will be used. Some words maybe used more than once. anaerobic aerobic glucose glycolysis long short the Krebs Cycle ATP fats cytosol mitochondria carbohydrates proteins presence absence Aerobic respiration occurs in the ______________________ of oxygen, while anaerobic metabolism occurs in the ______________________ of oxygen. The type of respiration you use depends on the intensity and duration of your exercise. In both types of cellular respiration, the first thing that occurs is breakdown of ______________________ through a process called ______________________ . This process occurs in the ______________________ of the cell. ______________________ respiration takes place at the onset of exercise for up to 90 seconds. ______________________ and intense exercise increases the rate of anaerobic respiration. If you exercise beyond 90 seconds, the cells rely on ______________________ respiration to make energy in the form of ______________________. Diet also plays an important part in creation of energy for your body. The nutrients we consume such as ______________________, ______________________ and ______________________ provide fuel for our cells to carry out cellular respiration. The anaerobic process relies solely on ______________________ to make energy. The aerobic process uses ______________________ and ______________________ to produce energy. 3. Place a check mark beside each activity that relies only on anaerobic respiration. o Running a 100 m sprint o Running a marathon o Taking a 30 minute dance class o Power lifting o Box Jumps o Playing a soccer game 4. What is creatine? ________________________________________________________________________________ ________________________________________________________________________________ 5. Why do people take creatine supplements when weightlifting? ________________________________________________________________________________ ________________________________________________________________________________ 6. How does your body use creatine? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 7. What are the side effects associated with creatine use? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ MITOCHONDRIAL DISEASES 1. What are mitochondrial diseases? ____________________________________________________ ________________________________________________________________________________ 2. What causes mitochondrial diseases? _________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________ 3. What are common symptoms of mitochondrial diseases? ________________________________________________________________________________ ________________________________________________________________________________ 4. Is there a cure for mitochondrial diseases? Yes or No 5. Treatment for mitochondrial disease varies depending on the type of disease and symptoms. What are common treatments for mitochondrial diseases? ________________________________________________________________________________ ________________________________________________________________________________ ________________________________________________________________________________
