Question

Shown here is a diagram of a mitochondrion showing four processes that were discussed in class. W, X and Z involve movement of solutes (arrows) across one or both membranes, and Y is a series of reactions in a cycle. Use this diagram to answer the following four questions. Oxygen directly participates here: A) Z. B) Y and Z. C) X. D) W. E) Y. CO_2 is produced here: A) W. B) X and Y. C) X and Z. D) X. E) Y. Electron carriers get reduced here: A) Y. B) W, X and Z. C) Y and Z. D) W. E) X and Y. Electrons originally in glucose will flow in this order: A) X rightarrow Y rightarrow Z B) W rightarrow Z rightarrow Y C) Y rightarrow W rightarrow Z D) X rightarrow W rightarrow Z E) X rightarrow Y rightarrow W

Explanation / Answer

answers:

11) A

Explanation: Oxygen join with protons and electrons to form water

12) E

Explanation: Acetly coA converted to 2ATP and C02 molecule occur in cytosol (Krebs Cycle)

13) B

Explanation: Electrons provide energy to pump protons across the membrane

14) C

Explanation: glucose occur in the cytoplasm> Pyrruvate then has to come across the membrane. Glucose converted to carbon dioxide and ATP
