Cellular Respiration in Three Acts
Act I: Glycolysis 1. Tell us where this happens. 2. Tell what the purpose of glycolysis is (what is/are the ultimate products?) 3. Identify each actor and tell us who they represent. You should have at least the following players (some people may have to play more than one role; all people should have a sign to indicate who they are): a. Glucose b. 2 ATP (consumed or produced?) c. Pyruvate d. Enzymes (don’t worry about identifying individual enzymes, just discuss that they are used to make the final product) e. 4 ATP (consumed or produced?) f. 2 NADH (consumed or produced?) g. Pyruvate 4. Describe what happens—each actor must ACT OUT their part, not just stand there and smile. 5. Be sure to also address/define the following in your discussion: a. Is glucose oxidized or reduced to make the final products? b. Where does the NADH go next? c. Where does pyruvate go next? Cellular Respiration in Three Acts
Act II: Krebs Cycle 1. Tell us where this happens. 2. Tell what the purpose of the Krebs Cycle is (what is/are the ultimate products?) 3. Identify each actor and tell us who they represent. You should have at least the following players (some people may have to play more than one role; all people should have a sign to indicate who they are): a. Pyruvate b. Acetyl CoA c. Citrate d. Isocitrate e. Alpha‐ketoglutarate f. Succinly CoA g. Succinate h. Fumarate i. Malate j. Oxalocaetate k. NADH l. ATP m. FADH2 n. CO2 (comes from the break down of what?) 4. Describe what happens—each actor must ACT OUT their part, not just stand there and smile. 5. Be sure to also address/define the following in your discussion: a. As each intermediate molecule becomes the next molecule, is it being oxidized or reduced? b. Where does the NADH and FADH2 go next? c. What are all the final products of the Krebs Cycle? d. Where does the CO2 come from?

Act III: The Electron Transport Chain 1. Tell us where this happens. 2. Tell what the purpose of the Krebs Cycle is (what is/are the ultimate products?) 3. Identify each actor and tell us who they represent. You should have at least the following players (some people may have to play more than one role; all people should have a sign to indicate who they are): a. Complex I b. NAD
NADH c. Complex II d. FADH
FADH2 e. Q f. Complex III g. Complex IV h. ATP Synthase i. H+ j. Proton gradient (on the other side of the ?) k. O2 l. H2O m. ATP 4. Describe what happens—each actor must ACT OUT their part, not just stand there and smile. 5. Be sure to also address/define the following in your discussion: a. Where the proton gradient is created? b. Why the proton gradient is created? c. Where is oxygen consumed and WHY it is consumed? d. What does oxygen become after it is consumed?
