Preparation: Please review the notes from D2L as well as the presentations provided in the unit plan to complete this assessment.    Visual Representation: Please choose a few diagrams from the presentation, online or D2L that clearly illustrates the processes of cellular respiration. You would need an annotated diagram to explain the processes of cellular respiration which include the following: glycolysis, pyruvate oxidation, krebs cycle, electron transport chain, anaerobic fermentation. Your diagram can be presented in any way that you choose.    Recording: Using your diagram as a reference, please explain each of the processes in your own words using the key vocabulary learned in class. The major concepts have been highlighted in the presentation as well. You can use the screen recording feature, loom, canva and many more digital tools. In your recording, please make connections and relate concepts to real life examples.    Checklist:    Include steps in glycolysis, pyruvate…

CELLULAR RESPIRATION AND FERMENTATION Name: Date: Instructor: Section/Group: POST-LAB QUESTIONS 1. Both cellular respiration and fermentation ordinarily begin with which molecule? ves 2. What role does cellular respiration play in the metabolism of an organism? 3. Glucose breakdown results in the breaking of C-H bonds and stored energy is released. Compare and contrast the end products of fermentation and cellular respiration in terms of their energy produced. 4. Fermentation results in the net production of only 2 ATP, while cellular respiration results in the production of at least 36 ATP. Explain these results with reference to the end products of both of these processes. Cellular Respiration and Fermentation 93

IDENTIFICATION 1. A type of reaction that occurs when an energy absorbing reaction requires an input from an energy releasing reaction. 2. What does ATP stands for? 3. What does ADP stands for? 4. When a phosphate bond is broken energy is released from ATP. This type of reaction is 5. To reconnect the phosphate with ADP energy must be absorbed from the breakdown of glucose during cellular metabolism. This type of reaction that occurs with glucose is 6. A biochemical process that involves the addition of phosphate to an organic compound. 7. How many kilojoules is released with ADP is reduced to ADP? 8. ATP is also formed from the process of cellular respiration in the mitochondria of a cell through 9. ATP is also produced in bacteria in the absence of oxygen called 10. A method in food processing which can produce small amounts of ATP is called
