The first stage of cellular respiration is called ____________________________ 3. Glycolysis occurs in the cell’s _________________(organelle). It does not require oxygen to power it so the process is called a(n) __________________one. 4. The glucose molecule undergoes a series of chemical reactions to produce 2 molecules of a highly reactive chemical called _________________. 5. __________ (number) of ATP are used to rearrange the glucose molecule using a process called ____________________. 6. A total of__________ (number) molecules of ATP and 2 molecules of ______________ (coenzyme) are also produced during glycolysis. 7. The ______________ are a series of chemical reactions that take place in the mitochondrial matrix. 8. During this complete cycle, each _______________ molecule will go through a series of 9 reactions to produce ___________ ATP, ____________H2O, and __________CO2. 9. The electron transport chain occurs in the _____________ of the mitochondrion. 10. Here the high energy electrons from the ____________ molecule are released to help produce the maximum number of ATP molecules. 11. The final electron acceptor is a(n) _______________ molecule. 12. The total number of ATP molecules produced for each section of the energy making process are: a. Glycolysis ___________ ATP b. Kreb’s Cycle __________ ATP (once around) c. ETC ____________ ATP 13. One molecule of glucose, in the presence of oxygen, will produces a total of __________ ATP. 14. What is another name for fermentation? _________________________ 15. What are the products of plant fermentation? __________________________________ 16. What are the products of animal fermentation? ________________________________ 17. Where does fermentation take place in cells? _______________________________ 18. What happens to lactic acid after it reacts with oxygen? _____________________________ Graph Assignment: (16 marks) Temperature and pH have an effect on how fast glycolysis and respiration can occur. Below is a chart with data concerning an experiment carried out on the rate of glycolysis at various temperatures. Create one graph with two lines depicting the data provided. Ensure that it show trends (not a line of best fit) by connecting the dots. The graph must have consistent intervals, titles, and scales for each axes, a overall legend, and a title for the graph. Then answer the following questions regarding the graph. Temperature (°C) 5 10 15 20 25 30 35 40 Pyruvic Acid Production (mg/ml) Organism A Organism B 12 6 16 12 25 22 28 29 32 35 36 45 35 47 34 49 1. What would be a good hypothesis for the above data? 2. What is the dependent (responding) variable? 3. What is pyruvic acid? 4. How does knowing the amount of pyruvic acid help determine the rate of glycolysis? 5. Looking at the above data, which organism would one expect to function the best in cold weather? 6. Based on the graphed data, what conclusions can be made about temperature and the rate of glycolysis?
