2. Examine the two scenarios below. Scenario A: 100 g of glucose in the presence of unlimited oxygen is metabolized through aerobic respiration. Scenario B: 100 g of glucose in the absence of oxygen is metabolized through anaerobic respiration. Would the mass of products produced in Scenario A be greater than, less than, or equal to the mass of products produced in Scenario B? Justify your answer.

4. Write the overall balanced equation that summarizes glycolysis.

Activity: What's the Difference! Complete the table on the differences of aerobic and anaerobic respiration according to the basis of comparison below: Basis for Aerobic respiration Anaerobic respiration comparison Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives. Definition 1. The overall equation of aerobic respiration is: The overall equation of anaerobic respiration is: Overall equation C2HSOH + C6H1206 + 602 6CO2+ 6H20 + energy C6H1206 CO2 + energy Aerobic respiration takes place in the presence of oxygen 2. Presence of Oxygen The exchange of gases doesn't take place during anaerobic respiration. However, some gases like sulfur and nitrogen gases Exchange of gases 3. are released by some organisms. Aerobic respiration, after glycolysis, occurs in the mitochondria of eukaryotes and cytoplasm of prokaryotes. Location 4.

4. Anammox bacteria are known to obtain energy from the anaerobic autotrophic oxidation of one mole of NH4+ with N02- to form one mole of N2. (1) Develop an electron equivalent energy reaction for the anammox organisms. (2) Calculate ΔGr (kJ/1nol) for this reaction. (3) Calculate fs° for the anammox autotrophic reaction, assuming ε =0.4, N02- is the N source, inorganic carbon is the carbon source and Y is in g VSS/g N.

7. In the ketone body pathway, both acetoacetate and B-hydroxy butyrate are produced and become additional fuel molecules for the organism. a. Define where these molecules are produced (both tissue type and location in the cell) and what tissue they "feed". b. Of these two molecules, which one is considered slightly better in delivering more energy to the target tissue? Why? c. How does acetone, another ketone body, participate in delivering fuel to target tissue? d. If acetoacetate decarboxylase enzyme was mutated and became inactive (zero enzyme activity), how would this affect the ketone pathway during these conditions: į. immediately after a meal, ii. under starvation conditions, iii. during unchecked (not being treated for) type-1 diabetes.

4. You are examining a microorganism that is growing under anoxic conditions with no available terminal electron acceptors for NADH. Describe how this organism will go about catabolizing glucose under this condition.

1. Describe in a step-by-step fashion how cyanide poisoning causes a stop of ATP production in a mitochondria. 2. Describe in detail how cyanide poisoning affects Anaerobic Metabolism

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
