Getting energy to make atp part 2 (pp.232-233) answer key

  1. 1. CENTRO ESCOLAR SOLALTO 9th Pre-IB Biology Teacher Javier Aguirre, B.A. NAME_____________________________________ Date: 07/14/10 Getting Energy to Make ATP Part 2 (Section 9.2) Materials: • Notebook • “Biology – The Dynamics of Life” textbook Instructions: • Paste and complete today’s handout in your notebook • Read pages 232 and 233 of your textbook and answer the following questions. 1. What is the other name for the citric acid cycle? Krebs cycle 2. Why is the citric acid cycle a cycle? It is called a cycle because a four-carbon molecule of oxaloacetic acid is used in the first reaction of the cycle and it is also one of its end products. 3. How many molecules of ATP and CO2 are produced each time the cycle turns? One molecule of ATP and two molecules of CO2 are produced each time the cycle turns. 4. What are NAD+ and FAD? How many molecules of NADH, FADH 2 and H+ ions are formed during the citric acid cycle? They are electron carriers. A total of three NADH molecules, three (3) H +, and one FADH2 molecule are formed. 5. How many energized electrons do each electron carrier pass to the electron transport chain in the inner membrane of the mitochondrion? Each electron carrier passes two (2) energized electrons along to the electron transport chain in the inner membrane of the mitochondrion. • Please reproduce Figure 9.10 and answer the critical thinking question in your notebook.
